When you have counted and recorded your answers perhaps you could use them to solve some problems.
How many altogether? (Choose two objects to count altogether)
Can you write a number sentence e.g. 5+3=
What is 1 more than ....?
What is 1 less than...?
Can you put the answers in order from smallest to largest?
Which numbers are more than...?
Which numbers are less than...?
As a challenge you could use your 100 square to find out 10 more than some of the answers.
