5 Maths Gems #12

This is going to live on a relatively brusk gems ship service because I'm exhausted from entertaining xix toddlers this afternoon at my daughter's 3rd birthday party. So I'll live on brief today, but facial expression a lengthier ship service side yesteryear side calendar week when I've recovered.

1. Area of a circle (again)
In my seventh gems post I shared an applet that beautifully demonstrates how to derive the surface area of a circle yesteryear cutting it into sectors. This calendar week I establish a vivid gif that shows the same thing.

This gif is taken from the animatics (animations + mathematics) section of @MathsChallenges' website. The thinking behind this method is neatly explained in Geometry: What is the intuition behind the formula for the surface area of a circle? which was shared this calendar week by @GeometryDad.

2. Standard form

'resources library has or too thence corking ideas.

3. H5N1 grade resources

I saw this tweet from @DrTrapezio...

too thence I checked this out too establish that the Cambridge Mathematics Education Project is inviting schools to register every bit affiliates to gain early on access to their gratuitous H5N1 grade maths resources nether development. I'm e'er on the facial expression out for H5N1 grade resources too thence I registered. There's loads of corking materials on the website too I facial expression forrad to seeing the collection develop. 

Some of the CMEP's resources are forthwith featured on NRICH. For example, the question below is vivid (and non every bit difficult every bit it looks...)

I too similar the 'always, sometimes, never' bill of fare form 'Discriminating'.

Extract from Discriminating

And Parabella is a lovely work for your Year 12s studying coordinate geometry.

4. Operation Countdown

H5N1 combination of ideas too inventiveness from @LWmathsmatters, @EJmaths too @taylorda01 led to this first-class 'Operation Countdown'. I frequently role the 'four threes' activeness every bit a plenary inward an monastic say of operations lesson amongst Year 7 but it industrial plant amongst whatever historic menstruum group. I in i lawsuit used it every bit a Year xiii starter too they actually enjoyed it. The version below involves 5 threes but it's the same idea.

This film is from @taylorda01. @EJmaths also made this PowerPoint which includes a dark too white version.

5. #units #ruler #workings 

I read the ship service 'Hashtag closure' yesteryear A identify for gimmicks?'). David's ship service is close using a hashtag to summarise a lesson. 

Then A Frenzy of Marking: 'Progress Over Time' close feedback stickers. When I mark, I create notice that I write the same thing over too over again, too thence stickers would salve me a lot of time. Problem is, I'm non organised plenty to role stickers. I create my mark inward a multifariousness of locations too unremarkably but receive got a reddish pen to hand. Hashtags volition function but every bit good every bit stickers, every bit long every bit my students empathize the important of the hashtags.

When I grade I'm non succinct enough. For lawsuit I frequently write 'please larn to assistance companionship at 1.30pm on Midweek inward Room 111 for assistance amongst this topic'. Instead, I could write #helpclub. I too write things similar 'Look at the enquiry - yous were meant to circular your reply to i important figure'. I could but write #rounding. My students volition larn what I hateful (especially if they receive got this key inward their practise books) too it volition salve me loads of time. "What's the quest inward the # symbol?" I take away heed yous inquire - well, yes, the symbol isn't essential, but #MrsMorganLikesHashtags too they're non doing whatever terms are they? :)

So that's it - 5 quick gems from a busy mathematical mum. I was planning to characteristic or too thence thoughts close the value (or lack of value) of iPads inward maths didactics today but didn't larn fourth dimension to create the enquiry required, too thence volition salve that for my side yesteryear side gems post.

I'm too planning to write a ship service close circle theorems side yesteryear side week. I've got or too thence ideas but if you

receive got an interesting means of teaching circle theorems or whatever amazing resources, delight allow me know.

Also, don't forget to cheque out my other website, prethomework.weebly.com - the extensive collection has grown over half-term.

I'll larn out yous amongst a base of operations eleven abacus which I squall upwards is cute but volition annoy @solvemymaths (see his ship service 'My Base eleven Abacus Bugbear').

5 Maths Gems #30

Hi together with welcome to my 30^th gems post. This is where I percentage only about of the best teaching ideas I've seen on Twitter.

1. Construction Comics
Back inwards Gems 4 I featured Paul Collins' (comic resources for teaching constructions. In his post he suggests only about opportunities to role these resources inwards the classroom.

One of Paul Collins' structure comic strips 

I haven't taught constructions this twelvemonth hence I've non nevertheless had a run a hazard to role these resources, or the awesome Gems 21).

I loved the operate shared yesteryear my namesake Mrs Morgan (@em0rgan) on Twitter this week. She asked her students to do their ain structure comic strips for homework. The results facial expression excellent. I'm non unremarkably a fan of homeworks similar this because they're hence fourth dimension consuming (both for students to gain together with teachers to mark) together with oft they don't add together much value. But inwards this instance I intend at that topographic point is value inwards students learning the procedures yesteryear documenting the steps, inwards improver to practising the constructions.

2. Influenza A virus subtype H5N1 Level Resources

Thanks to @OxfordEdMaths for sharing a gear upwards of excellent A degree assessments for C1 - C4, D1, D2, FP1, FP2, M1, M2, S1 together with S2. It tin endure difficult to honor sources of expert Influenza A virus subtype H5N1 degree questions. These gratis resources are going to endure incredibly helpful adjacent twelvemonth for theme assessments, homeworks or revision.

Speaking of Influenza A virus subtype H5N1 degree resources, do banking concern agree out the website 0a explains: Calculus (with pics together with gifs) -thanks to @mathhombre together with @solvemymaths for sharing this. I dear the pictures together with gifs on this website - they mightiness assistance teachers explicate concepts inwards calculus.

3. Homework Expectations
I've only discovered MathFour.com from Bon Crowder - it's total of creative ideas, only about of which I excogitation to characteristic inwards hereafter gems posts. One persuasion that I spotted was a 'How to Write Your Math Homework' guide. I'm going to brand a version of this for my novel classes inwards September. I can't complain nearly my students' operate non coming together my expectations if I haven't made those expectations clear from the outset.

4. Talk a Mile a Minute
Steve Wyborney (@SteveWyborney) shared his Talk a Mile a Minute Vocabulary Activity. The video below describes the activeness inwards detail. It involves students describing sets of words to their partner together with and hence discussing what those words relate to. I intend this would endure a cracking activeness for an terminate of twelvemonth lesson. Have a facial expression at Steve's post for resources. If you're looking for words for this activeness together with hence try this Vocabulary Checklist for Key Stage 3.  

5. Activities

I've seen only about lovely activities together with questions on Twitter this week.

@MathedUp shared this 'Negative numbers code-breaker activeness amongst a twist'.

Gems 29.

@DJUdall shared this activeness which links solving equations amongst expanse together with perimeter.

@DJUdall likewise shared a query he made which combines Pythagoras' Theorem together with Standard Form. 

The latter 2 resources were shared during concluding Sunday's #mathsTLP. This is a cracking identify for maths teachers to collaborate. Do bring together inwards on Sundays at 7pm to enquire for assistance amongst lessons or to offering ideas.

Update
Because my examination classes are directly on report acquire out I had fourth dimension to excogitation only about actually prissy lessons this week. With my Year 10s I did a lesson on similar triangles using resources from the Mathematics Assessment Project. They had to kind 8 pairs of triangles into 'similar', 'not similar' or 'can't tell', drawing on their cognition of angle facts. This project is a lot harder than it sounds together with takes nearly 45 minutes to complete. I actually recommend it - here's an instance of the operate they produced hence you lot tin see what it involves.

I talked to all my students nearly palindromic numbers this calendar week (I remembered to yell it every fourth dimension I wrote the appointment on the board, because the dates were palindromic when written inwards the format m/dd/yy). Although many of my students could plough over me an instance of a discussion that is the same frontward together with backward (eg racecar), most were non familiar amongst the discussion palindrome.

Those of you lot who role Gems 10) for formative assessment volition endure pleased to listen that you lot tin directly insert pictures. For instance you lot mightiness desire to insert questions from www.diagnosticquestions.com.

That's it from me for now, but at that topographic point volition endure only about other gems post presently because there's been loads of cracking materials on Twitter lately. Wish me luck amongst my concluding calendar week at my electrical flow school! My novel project starts afterward half-term.

I'll acquire out you lot amongst this GCSE resource by thornn on TES (shared by @eggarsmaths on Twitter) which you lot mightiness honor useful for concluding infinitesimal examination tips over the coming weeks.

5 Maths Gems #34

Hello in addition to welcome to my 34^th gems post. This is where I percentage 5 educational activity ideas I've seen on Twitter. The summertime holidays are survive here! Let's live honest though - although it's lovely to conduct maintain the chance to remainder in addition to play, the bulk of us practise a fair amount of schoolhouse operate over summertime - creating resources, organising in addition to tidying, preparing for September, catching upward on reading... Have yous read all 34 of my gems posts? Now's a skillful fourth dimension to start!

1. Magnitude
Standard Form is all nigh actually large numbers in addition to actually pocket-size numbers. It's overnice to set the theme into context - I've written a few times nigh The beauty of the real very large in addition to the real very pocket-size – Standard form' by @mhorley. Thanks too to the lovely @MissBLilley who shared this video which puts size into context - she used it to innovate Standard Form in addition to her students were amazed!



2. Prime Time
@MathedUp shared a overnice activity on prime number element decomposition. I actually similar this because it makes it hence clear that every set out is either prime number or composed of primes.

I honey this prime clock from the vivid Minimal Math Concepts. Influenza A virus subtype H5N1 few tweeters were unhappy to reckon the set out i on it though!

Whilst on the dependent area of primes, banking concern gibe out this first-class primes in addition to factors puzzle from @LearningMaths:

@LearningMaths ever produces first-class resources. Here's to a greater extent than or less other twosome of examples:

Fractions starter by @LearningMaths

Number machines by @LearningMaths

3. Alphabet Lesson
In a Twitter news nigh commencement lessons of the year, the ever creative @missradders shared an thought for a Maths Alphabet lesson. In this lesson, students come upward up with the best news they tin for each letter. They need to live able to tell yous what it agency - for instance for the missive of the alphabet Influenza A virus subtype H5N1 they mightiness define add, angle, area, average, astute or adjacent... As Hannah says, "this is a skillful estimate of prior knowledge/ability ... in addition to gives yous fourth dimension to chat to them". What a lovely thought for a commencement lesson with Year 7.

If yous desire to conduct maintain this thought further, your class could blueprint in addition to attain a maths alphabet poster similar the examples shown below.

Last twelvemonth I wrote a post 'Your First Maths Lesson with Year 7' which has lots to a greater extent than ideas for September.

4. Influenza A virus subtype H5N1 Level Prompts
@dannytybrown has been busy developing a serial of pre-teaching prompts for Influenza A virus subtype H5N1 score topics. These are designed to live given to students a few days earlier a theme is taught. They are intended to prompt shape news in addition to potentially trim back the variation inwards prior noesis alongside students. Influenza A virus subtype H5N1 few examples are shown below. Do go on an optic on Danny's weblog squeaktime.com for to a greater extent than on this.

 5. Maths with Pizzazz
Thank yous to @japleen_kaur1 for sharing a prepare of resources I've never seen earlier - Maths with Pizzazz worksheets. Hundreds of topics are covered. Many of the activities involve practising skills in addition to using answers to operate out riddles in addition to jokes. Here's a twosome of extracts:

Extract from Page 211 - Algebra with Pizzazz!

Extract from Page 159 - Pre-Algebra with Pizzazz!

I could pass days looking through these resources! Thankfully there's an index. What I actually need to practise is split upward the PDFs into separate worksheets, labelled in addition to grouped past times topic. But that would conduct maintain weeks. Any volunteers?!
