The interactive math worksheet has been designed to help your child to learn to add and subtract numbers up to 10.
Addition and subtraction to 10 is a key skill that children need to learn to progress further with their mental math.
Pupils have to take the envelope with the addition or subtraction account to the appropriate house to help the postman deliver the mail.
If they make a mistake, they can correct it several times.
The game also provides timekeeping. If students play it repeatedly, they can check how much progress they have made in adding and subtracting to 10.
