Happy Thanksgiving! & Math Activeness Thursday: 4.Md.A.3

I promise everyone is having a wonderful Thanksgiving!  I receive got thence many things I am grateful for--family, friends, a home, food, as well as many to a greater extent than blessings.  I promise nosotros tin laissez passer on the sack all accept a infinitesimal or 2 as well as intend virtually all nosotros receive got to locomote grateful for.

Now fourth dimension for MaTh activity Th alongside CCSS 4.MD.A.3: Apply the surface area as well as perimeter formulas for rectangles inwards existent globe as well as mathematical problems. For example, discovery the width of a rectangular room given the surface area of the flooring as well as the length, yesteryear viewing the surface area formula every bit a multiplication equation alongside an unknown factor.

I dandy majority for this is Spaghetti for All yesteryear Marilyn Burns.  It covers perimeter (setting upwards chairs) alongside the same total of surface area (tables).  It's a clever book.


I produce receive got an activity for today.  I honey doing to a greater extent than opened upwards ended activities than worksheets (as you lot powerfulness receive got gathered if you lot read my spider web log really often).  So hither it goes.

What's the missing value?
Supplies: 2 groups of 3x5 cards (one grouping has the numbers 2-10 as well as the other grouping has 12-25), grid newspaper for the children to locomote alongside as well as depict out the answers.
Lesson: Discuss the 2 formulas of surface area as well as perimeter as well as produce a few samples together.  Area= length x width, Perimeter= (length x 2) + (width x 2)
Instructions: For this activity you lot volition locomote picking 1 carte du jour from each of the 2 piles.  The carte du jour from the 2-10 pile volition locomote the length as well as the carte du jour from the 12-25 carte du jour volition locomote the surface area or perimeter (depending on which 1 you lot are working on).

You tin laissez passer on the sack larn the surface area freebie here.

as well as the length activity here.

as well as if you lot postulate grid newspaper to locomote alongside you lot tin laissez passer on the sack impress this

Sometimes the numbers you lot alternative powerfulness challenge the students because they volition receive got to role a fraction, merely I know they tin laissez passer on the sack figure it out.  You tin laissez passer on the sack ever alternative a unlike carte du jour if you lot know the children postulate it to locomote simpler.

If are doing surface area as well as you lot alternative 3 x ? = 22 they should depict out that length as well as and thence figure that they know 3x7 is 21 thence they postulate to split upwards 1 to a greater extent than block 3 ways ?= seven 1/3.

And if they are doing Perimeter as well as They larn an strange reveal they are going to postulate to receive got 1 distance locomote something as well as a half.

Let me know how it goes...  You tin laissez passer on the sack link upwards whatever math post service you lot receive got alongside Math activity Th until adjacent Wednesday.

Late Math Action Thursday: 5.Oa.A.1

I got busy the concluding distich of days together with didn't larn unopen to to my post, but improve belatedly than never...

5.OA.A.1 states: Use parentheses, brackets, or braces inwards numerical expressions, together with evaluate expressions amongst these symbols.

I felt that mathisfun.com explains the piece of work of these good on this page.  Basically, each pupil should already know the guild of operations (remember "Please excuse my dear Aunt Sally" ?).

1. Parenthases
2. Exponents
3. Multiplication or Division  (working left to right)
4. Addition or Subtraction  (working left to right)

As an activity for this CCSS I advise making an equation together with and hence throwing inwards some parentheses together with and hence some parentheses and brackets.  Then utter close how the braces gibe sets of numbers.

If you lot wanted you lot could accept set out cards to direct from together with and hence attain sum inwards the blanks.
Here's my sample.

9 + 10 - 5 ÷ 7  x four = ?

With no parentheses you lot piece of work left to correct amongst whatever G or D you lot find...

9 + 10 - 5/7 x four = ?

9 + 10 - 20/7 =

then larn out equally fraction or honor the decimal form.  2 6/7 or 2.857  I prefer fraction if it's non a overnice decimal...

9 + 10 - 2 6/7 =

Then piece of work left to correct amongst H5N1 or S.

19 - 2 6/7 = 16 1/7 or 16.143

Now the same occupation amongst some parentheses placed turns out differently.

9 + (10 - 5) ÷ 7  x four = ?

9 + 5 ÷ 7  x four = ?

9 + 5/7 x four =  9 + 20/7 = 9 + 2 6/7= 11 6/7

Now the same occupation amongst parentheses together with brackets turns out differently too.

[9 + (10 - 5)] ÷ 7  x four = ?

[9 + 5] ÷ 7  x four = ?

14 ÷ 7  x four = ?

2 x four = 8

How close i to a greater extent than parentheses?

[9 + (10 - 5)] ÷ (7  x 4) = ?

[ 9 + v ] ÷ 28 = ?

14 ÷ 28 = 14/28 = 1/2 or 0.5

It's form of fun seeing the dissimilar answers only because of a parentheses or 2 together with the math looks all complicated but it's truly quite slow : )

See you lot side yesteryear side week!  Have you lot done whatever math posts lately?

Kindergarten Math (Math Activeness Thursday)--Sorting Too Counting

Today I'm focusing on K.MD.B.3  which states Classify objects into given categories; count the numbers of objects inwards each category as well as kind the categories past times count.  You tin link upwardly amongst whatever Kindergarten post service you've posted inwards the past times or brand 1 inwards the side past times side span of days to add together your link.


Here's a fun action for sorting as well as counting.

Bring items to cast or lead keep pictures of about objects that lead keep ii or iii obvious categories.

The children kind the objects into categories they see.  In my illustration they powerfulness write or say: cars, route signs, as well as cookies.  
Then they count how many objects are inwards each category.  2 cars, iv roads signs, 2 cookies.

That's it.  I intend it would hold upwardly actually fun to lead keep a lot of diverse pictures for the kids then they could practise amongst lots of dissimilar objects as well as amongst dissimilar quantities.

Here is about other illustration that powerfulness lead keep dissimilar category choices fifty-fifty amongst the same picture.

It could hold upwardly considered vi circle things as well as vii foursquare things OR iv circle foods, vii crackers, & 2 plates OR they powerfulness only divulge xi foods as well as 2 plates.

There are belike to a greater extent than ways too!

Is in that place anyone who thinks they would purchase a pack of 50 pictures like to this for their classroom?

Math Action Thursday: Ccss.2.Nbt.A.1

Hey, it's that fourth dimension again...MaTh time

I'm actually looking forrad to afterward on today because I am going into my son's minute aeroplane class to read my storey Trouble alongside Monkeys: Influenza A virus subtype H5N1 house value storey together with create an action alongside CCSS.2.NBT.A.1

Just inwards illustration y'all haven't seen it yet, I'll embed it again.  Here is the storey I'll last reading : )

Then nosotros volition utter most the bottom of the house value nautical chart together with how it is inwards the story.

• The ones house is unmarried oranges, the tens are bags, the hundreds are boxes...

I made cards from my 1-100 cards I made for TpT together with added about to a greater extent than cards alongside only the hundreds place.  I'll essay together with update the cards on those sites ASAP.

We are going to accept ii students each choice a bill of fare from the hundreds bill of fare pile together with ane from the ii digit bill of fare pile.  We volition notice the number, write the numeral for the represented pose out together with thus tell which ane is greater or less than the other.

We mightiness too accept a grouping of students create this together with thus accept them draw of piece of job upwardly inwards ascending order.

I volition last continuing to accept the same linky each week.  You tin laissez passer on notice add together equally many sec aeroplane math posts equally y'all want.   Have a bully week!

Just an update!  It is official.  I volition last participating inwards the Influenza A virus subtype H5N1 to Z blogging Challenge in ane lawsuit again this year!  So during the calendar month of Apr I volition last having a novel weblog postal service Mon through Saturday, each alongside a topic together with the missive of the alphabet of the twenty-four hours : )  Wish me luck!

Math Amongst Guild (O Inward The A-Z Challenge)--Making Fraction Strips!

I know, I get got been skipping my MaTh activity Th due to the Influenza A virus subtype H5N1 to Z challenge, only I'm dorsum for today amongst a focus on 3rd flat (hip, hip, hooray)!  Add your link at the cease if it applies to 3rd grade.

So, my O post service for today volition live almost ordering (no, non ordering pizza--ordering numbers) 3.NF.A.2 as well as 3.NF.A.3

Most 3rd graders should live able to guild numbers actually well--putting a handful of numbers inwards to the lowest degree to greatest or greatest to least, only they may take away a picayune chip of do amongst fractions.  Actually, fifty-fifty some older flat students cope amongst fractions.

This is hands-on... Have the kids create fraction strips to larn almost how to guild fractions.  Yes, do non gear upwards anything else other than strips of newspaper (but they all get got to live the same length).  Have the kids plough the strips into halves, thirds, fourths, sixths, eights, nineths ( as well as mayhap twelvths as well as eighteenths if you lot want) yesteryear alone folding.  I advise you lot accept each fraction i at a time.

Into halves.

That i should live easy, only notwithstanding you lot should inquire a pupil how they did it.  How did they know it was half?

Then thirds.

Was this tricky?  What makes it difficult?

Fourths.

My 2d grader did it the fastest means amongst folding inwards one-half as well as thus inwards one-half i time again although my 5th grader brought both ends to the center, thus folded each side, as well as folded the middle last.  How do your students do it?

Sixths.

Is it hard?  How did you lot do it? (They volition respect out--or they mightiness already know that they flexure the thirds inwards half)

Eights.

Was this similar to whatever other way?  Maybe similar the fourths?

Just to run across if I could do it--I made a strip into fifths.  If some students desire to eyeball it, they can.  I folded the newspaper thus the 2 sides looked or thus the same every bit the interior section, thus finished the other 2 folds.

Here are the fractions strips!

Just doing this activity your students volition get got a ameliorate feel of how big fractions are as well as some of their equivalents 4/8 is the same every bit 2/4 as well as 1/2.  Seeing a slice of newspaper amongst fraction bars on it isn't every bit memorable every bit making the strips yourself.  You could select to extend this activity to get got the students solve/answer questions amongst them.

Do you lot do this type of activity inwards your class?

Don't forget to operate into my giveaway!  You tin operate into at the I as well as K post service here.

2Nd Class Math: Ccss 2.G.A.2 Stone Oil Expanse Of A Rectangle

Hi!  It's Th too thence fourth dimension for Math activeness Thursday!

All this calendar month has a sec grade focus.  Today's activity/lesson teaches CCSS.2.G.A.2 which reads...
Partition a rectangle into rows too columns of same-size squares too count to discovery the full position out of them.

Activity Name: Squarin' Up Rectangles!
Concepts: Area, shapes, measurement--Partitioning anything into squares is actually all nigh area.
Supplies: Easy--blank paper, ruler (recommend amongst cm measurement), pencil, too 2 colors (either 2 crayons or markers)
Time needed: xxx minutes for a class, but if doing at habitation it tin give notice last every bit lilliputian every bit 15.
Instructions:

1. Have educatee manus describe a rectangle on their blank page.  You may desire to remind the kids that rectangles corners are ninety grade angles (like an L shape), too thence when they describe their rectangle they create the best forthwith edges they can. (I used a pen, but students volition operate a pencil)
   
2. Using a ruler commencement at 1 of the corners too brand a grade at each centimeter. On each of the parallel sides (BTW y'all should operate these price amongst the kids--it's of import to learn math vocabulary early on) brand certain to commencement measuring at the same place.  For example, on the vertical lines I started measuring at the transcend too on the horizontal lines I started measuring on the left. (You could create this whole do amongst graph newspaper but your students wouldn't get got the challenge of making a grid inward their free-hand rectangle).
   
3. You volition in all likelihood discovery that non all the corners are just L shaped (90 grade angles) too thence y'all volition take away to redraw closed to of the sides to brand them straight.  Use the ruler to describe a business betwixt the ii measured points.
   
4. Explain that the columns become upward too downward (vertical) too rows become across, side to side (horizontal).  Most probable the rectangle volition non last an an exact cm mark--just operate the closest cm grade to a consummate cm)
   
   
5. Count the position out of squares downward each column too position out them (that is how many rows at that spot are).  In this instance at that spot are half dozen squares for each column.  Kids powerfulness non last able to count yesteryear 6s (or yet many rows they get got amongst their rectangles), too thence nosotros count the columns yesteryear 2s (you tin give notice count yesteryear 1s but it simply takes longer too y'all could create 3s too).  Each fourth dimension y'all brand a slash through the blocks y'all write the position out y'all are counting upward to (I drew a business nether each grouping of 3 numbers since that is 1 whole column).
   
   Keep going until y'all fill upward inward the whole thing--finding the expanse within the rectangle.
6. Now, to double banking concern tally that nosotros did the expanse correctly nosotros volition also count the squares inward the rows.  Label that--those are the position out of columns. Mine were slowly to count since at that spot were 10 squares inward each row.  Then I simply skip counted 10 every bit I marked the counting.
   
7. You powerfulness desire to inquire the kids which agency was easier for their rectangle--Counting yesteryear columns or counting yesteryear rows?  Explain to the students that they simply constitute the expanse of a rectangle.  It powerfulness get got been difficult to create it this way, but every bit they progress through math their volition last shortcuts to discovery the area.  Once they know multiplication it is simply the summit (vertical measurement) times the width (horizontal measurement).  In this instance nosotros had half dozen rows of 10 (6 x 10) or 10 columns of half dozen (10 x 6), but equal the same lx squares.

I promise y'all enjoyed Squarin' Up Rectangles!

Now it is your plough to portion a math activeness if y'all want.  Here is the template too y'all tin give notice link upward your sec grade activeness whatever fourth dimension this month.  In other months nosotros volition get got other grades too.

I can't expect to consider what kinds of activities y'all have!

2Nd Class Math: Autumn Rekenrek For 2.Oa.B.2 (Adding & Subtracting Inside 20)

Hey everyone!  Just a reminder that my house value items are on sale (20% off) until this evening on Teachers Notebook, thus if you lot haven't gotten them already, banking enterprise lucifer it out.

Today for MaTh we'll brand a fun autumn Rekenrek to practise adding as well as subtracting inside 20.  You tin laissez passer notice bring together inward the linky MaTh political party for a few to a greater extent than days (this is our concluding calendar week on s grade--next calendar month 3rd).

Okay, here's or thus of the supplies...

 and this is what it looks similar afterward it is set together.

Kids tin laissez passer notice decorate as well as set their cite on their personal Rekenrek leaf.

Instructions:  Once you lot accept assembled the Rekenrek yesteryear stringing all the beads as well as tying the ribbon inward the dorsum it is fourth dimension to play!

• Have students practise a few problems of their ain (9+8=_, or 7 +3=_) proverb it quietly to themselves.
• Then accept them practise amongst flash cards equally a class, pocket-size groups, or individually.

Rekenreks are keen because it helps the children run into how unmarried digits relate to the v as well as 10.  They tin laissez passer notice run into that 8 is genuinely 5+3 as well as when they are adding or thus other break to that, such equally 3, they tin laissez passer notice visualize as well as motion the beads to run into that 2 to a greater extent than makes 10 as well as and thus at that topographic point is however ane to a greater extent than bead for a full of eleven.

What kinds of activities are you lot doing amongst your students?

You tin laissez passer notice add together your s bird MaTh today or until the halt of the calendar month : )

See you lot Sat amongst a particular invitee weblog post!

3Rd Assort Math: Fractions On A Reveal Trouble Ccss 3.Nf.A.1-3

Hi!  It's Th together with it is the concluding calendar week of the calendar month doing a 3rd degree math activity!  Today I'm focusing on CCSS 3.NF.A.1, 3.NF.A.2, together with 3.NF.A.3 which is all nigh identifying fractions together with plotting them on a release business (halves, thirds, fourths, sixths, together with eighths).

So I made an slow freebie for you!

When it is filled inwards it looks similar this...

Essentially, kids are cutting out business office of the release business (on page2) together with folding them into release bars together with labeling them!

Get your re-create HERE.

I'm ever a piffling lean on the instructions, simply it genuinely is a hands-on activity you lot tin produce equally the students are doing theirs.

Have a smashing weekend!

How produce you lot similar to learn fractions?  Do you lot purpose release lines at all?

Money Freebie Which Volition Ever Hold Upwards Free! Plus, Math Alongside A Play Store! 4.Md.A.2

How oft is coin ever free?  Well, I believe kids should live able to play amongst pretend money every bit much every bit they want!  It's groovy exercise amongst math skills.

So, I desire to brand certain everyone knows that on kidsmenubooks.com you lot tin impress play #MenuMoney whenever you lot require to.  It lasts longer if you lot set it on cardstock together with it looks actually cool when the cardstock is brilliant together with colorful!

While the coin is meant to live played amongst the books I am publishing, it tin also live used anytime to attention you lot every bit your students exercise amongst money!  I don't convey the penny shown here, exactly at that spot is 1 on the site.

I promise you lot savour them together with tin set them to skillful use.  Here is an activeness you lot tin create amongst your students!

I'd honey to come across what MaTh things you lot tin part too.  You tin link upwards each calendar month every bit nosotros rotate through the degree levels K-5 every 6 months : )

Here's your template if you lot desire to brand upwards a Math activity!

See you lot side past times side time!

Two Invitee Weblog Posts For My Mass : )

I was then excited to live highlighted past times a duad blogs lastly week.  I've been then busy, I finally larn to write a fleck close it!

The Pen & Ink weblog is mainly followed past times writers.  I am happy to know most of the authors of that grouping weblog as well as they are swell people as well as amazing writers.  The link to that post service is correct here: My Journey to Kickstarter as well as Self Publishing

I got to portion close why I chose to run a Kickstarter to help me give away my mass likewise every bit roughly of the sources as well as plans of how I volition live publishing independently.

The side past times side weblog I was featured inwards is a instructor who constitute me on Twitter @KidsRead09 .  She made a pocket-size Q&A weblog post service entitled: The Pancake Menu: Engaging Math Games.

The business office I dearest most close that invitee post service is she asked which Common Core standards tin plough over the sack live taught amongst The Pancake Menu.  The respond is... SO MANY!!!  Check out that post service as well as run into all the CCSS I identified tin plough over the sack live taught using my book--K-5!

If you lot desire a re-create of the book, hurry as well as jump on Kickstarter to pledge for a hard-cover book.  Please spread the give-and-take then it tin plough over the sack live funded.  Thanks!
