## Famous numbers sequences card sort

Here’s a card sort I made to introduce my new year 7s to famous number sequences. The idea is students cut out and group the cards into 6 famous numbers sequences: Square numbers Cube numbers Triangle numbers Fibonacci Sequence Even numbers Odd numbers Each group should contain: Name Pictorial representation The numbers A fact about the sequence An explanation of how...

## Negative number reasoning with patterns

How do you explain that subtracting a negative has the same effect as adding the positive corresponding number? I’ve seen teachers use many analogies including: Thinking of sandcastles as +1s and holes as -1s… a sandcastle and a hole makes nothing (1 + -1 = 0). Playing golf and you score -2 on a hole, taking your score from -4...

## A sequences alternative to ‘how many matchsticks’

You ask them to spot the term-to-term and position-to-term (nth term) rules and feel great if they do. I’ve taught this lesson a few times at differing ability levels this year and the other...

## What does the cube look like?

I created this worksheet based on a problem on the excellent NRich Maths website. The pupils have to use their skills of visualising 3D shapes to draw patterns on the faces of a cube net after deciphering where they should go by looking at 3D views of the cube. To scaffold the task an actual cube net is also included...

## Giving rotational symmetry the ‘wow’ factor

This video is taken from the iTunes Visualiser called Jelly that makes pretty patterns that react in real time to the music that is playing. The patterns produced show rotational symmetry and could be used as an excellent resource in a starter or plenary on the topic. Download this video in 3GP format here.

## Introducing algebra- consecutive numbers addition puzzle

Here’s are really good way of introducing algebra and getting across the idea of what a variable is. The pdf slides that you can use on the interactive white board to run this activity are here. Start by getting the pupils to draw this diagram in their books: They then choose a number between 1 and 10 and write this...
