I can’t take all the credit for this maths game, as I adapted it from one we play in Maths club at school. The game in school has 4 tunnels with numbers 1-4 on them, the idea being that you take turns to roll a marble through the tunnel’s adding up the numbers as you go, the winner is the first to 10.
We made more than 4 tunnels, used higher numbers and added a ‘minus’ tunnel. Z wanted to play that the winner was the first to 40.
We had to use bigger balls too, as marbles are a bit small for Baby H.
This game has been brilliant for practising mental arithmatic with Z, and practising number recognition with S.
