I’ve already posted a game involving this snake about the solar system, but there are many ways to use it just to teach basic math.
This snake has 100 squares. The first thing the child needs to notice is that the colours repeat in patterns of 5, so blue is always a multiple of 5. You can have the child place nickels and dimes on the blue sqaures to learn how this works.
Then for practice in counting, place raisins or candies on random squares. Players take turns to draw two numbers out of a bag, say a 3 and a 7. The player counts to the 37th square and/or the 73rd to see if there’s a treat on it. The game ends when the treats are gone. It will take time for the child to recognise that skip counting by 5s makes it easier.
