would like you to practise these at home.
During the holidays we
would like you to challenge yourself and your family.
Start by thinking of a number. (e.g. 10)
Now add 1. (e.g. 11)
Now take away 1. (e.g. 10)
Now add 10. (e.g. 20)
Now take away 10. (e.g. 10)
Can you write each one in a number sentence in
your book?
What is the highest number you can start on and
still be able to add and take away one and add and take away 10?
