Maths Investigation

We have been investigating different problems using number lines in partners. We had to discuss with out partner why we thought our answer was correct and what we had done. 

I jumped on....because....
I know the answer is.....because.

We then had to find out the secret jumps, such as: Miss Stanley makes a jump of 5 and then a secret jump. She lands on 12. How much was her secret jump?

Can you write some of your own?
