I'm Eight

Find a great variety of ways of asking questions which make 8.

Month Mania

Can you design a new shape for the twenty-eight squares and arrange the numbers in a logical way? What patterns do you notice?

Magic Plant

On Friday the magic plant was only 2 centimetres tall. Every day it doubled its height. How tall was it on Monday?

What's Left?

Why do this problem?

This problem will help young learners to come to some understanding of factors and multiples leading to a first introduction to the idea of prime numbers. They will need to look at multiples of $2$, $3$ and $5$ up to $20$. For some children just making the table to use will be a useful exercise.

Key questions

Do you know the name of the numbers you have coloured in now you have done the sharing by $2$?
Do you know the name of the numbers you have left out now you have done the sharing by $2$?
Which multiplication table will you find these numbers in?
Which numbers have not been coloured in at all?

Possible extension

Learners could make a grid which goes up to $40$ or even $100$ adding $6$ and $7$ to the "red" numbers.

Possible support

Suggest starting by making the table to use. Then colour in the numbers counting in $2$s omitting $2$ itself.
