How to do it:
You will need:
A number grid to 20 and a car or small toy.
If you don’t have a grid you can make one like this.
If you find it tricky:
Gather 10 objects and ask your child to count out a number, then add one, ask then to say the number sentence
Ask your child to count out 5 object then add 1 more
5 add 1 more more = 6
Repeat with different numbers.
Can you say one more or less to 20?
Write the numbers 1-20 on separate pieces of paper.
Put them face down and mix them up.
Pick a number and work out what is one more and one less than that number.
