## Angles in parallel lines- FUN

I’ve seen lots of mnemonics for remembering the angles in parallel lines facts; “Cangles, Fangles and Zangles” etc. A student I teach who recently arrived from South Africa told me he’d been taught it as “FUN”. I like š

The nodes are connected by 935 links. Each link represents a connection between two topics whereby one is the prior...

## Volume of a sphere to calculate the capacity of your lungs

Just a quick idea here… To make a lesson on calculating the volume of a sphere contextually meaningful how about using a balloon to calculate the capacity of your lungs? Get a pupil to take a deep breath and then fully exhale into a balloon. Then measure the radius of the balloon and calculate the volume. You’ll need too get...

## Numberphile- videos about numbers and stuff

Numberphile.com is a website your pupils simply must know about. It describes itself as “videos about numbers and stuff” which is a pretty good summary in my opinion. The videos are not tutorial skill-based offerings, but engaging adventures into interesting mathematical concepts and problems. I really like them as they show maths at its best: interesting problems andĀ fascinatingĀ results, rather than...

## 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...

## Surface area of spheres- an apeeling lesson…

How do you give pupils a beautiful visual picture of why the surface area of a sphere is 4 pi r squared? A super lesson idea I heard recently involved an orange! Give pupils an orange and a blank sheet of paper. They have to draw circles around the orange onto the paper. The idea is that the circles on...
