## Functional area questions

I put together the following as an activity for a low-attaining year 8 class coming to grips with area. They’ve done area of rectangles and triangles last lesson and so I’m trying to link it to real world contexts this lesson. The idea is they cut out the shape for which they need to find the area, they then choose...

## Triangle constructions tangram

A colleague of mine, Claire Nealon wanted to adapt a resource I made a while ago of a triangle constructions tangram (see previous post). She wanted to make it more accessible for lower attaining students. Claire simplified the constructions so that the triangles are all right angled with side lengths that are Pythagorean Triples. This made the activity more accessible...

## The Chaos Game- a very surprising result

Created by Michael Barnsley, The Chaos Game is a deceptively simple idea, but the results are astonishing. Start with an equilateral triangle, a pencil, a ruler and a die. Label one vertex of the triangle “1 and 2”, the next “3 and 4” and the final one “5 and 6”. Mark a dot on one of the vertices of the...

## Area and Perimeter Follow Me Cards

If you have never seen www.mrbartonmaths.com then you are seriously missing out! Mr B’s website is packed full of great maths teaching resources. These include some excellent ‘follow me cards’ for area and perimeter of squares, rectangles and triangles. I took this resource and slightly changed it so that the question and answers are not adjacent to each other on...

## Tangram Constructions Fun

A huge thank you to Mr S for this wonderful idea! Make a lesson on triangle constructions much more interesting by getting the pupils to create triangles that form parts of a tangram puzzle that they then go on to solve. Wonderful idea! Click here to download the resource

## The Area Song…

How do you teach kids to remember how to calculate areas of shapes? Here’s one method… Sing the following song to the tune of Pop Goes The Weasel: Verse 1: Multiply the length by the width Gives the area of a rectangle. Base times height divided by two Now gives a triangle. Verse 2: Half the sum of the parallel...
