Sorry everyone, the activity won’t copy and paste on properly, so I have tried to take pictures of it, let me know if this does not help.

Activity: I can count on and back. 

Fill in the missing numbers into the box (verbally or written)

Challenge: I can create my own Q.

I can use the numbers given to form an addition or subtraction calculation.

I can solve the calculation and show the count on/ count back method.

Finisher: Explain verbally or written, how to use the count on/ back method and why this might be helpful.
