Mid Winter Maths Challenge

On your topic reports you have been given your next steps.  We       
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?
