Number Ping Pong

This is based on a game that my 4 year old daughter loves to play at school with her teacher. The teacher says a number and then the children need to respond as quickly as possible with the correct number that adds up to 10. The aim of the game is to teach children number bonds.
There are 6 games covering numbers 5 to 10 and each game is timed, so not only do the children learn the number bonds, it encourages them to respond as quickly as possible.
There are no adverts or in app purchases so it is safe for children to use.
This game is suitable for children aged 4+
