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.
