Why play this game?
This game is to help children to understand the tens and units structure of the numbers to a hundred. It can be used as an activity for one child on their own or by up to three at once. If there are four, it would be more suitable to play two parallel games.
You could sit with the children who are to play until they understand what they have to do when they reach "9". Once a pair understand the game you could give them the task of teaching others by playing with them.
What do you do with the second counter when you reach "9"?
What do you do with the first counter when you reach "9"?
How many more tens until you get to "100"?
Learners could use two dice and add the results.
A child who is struggling to understand may need to play the game with an adult first before playing with their friends.
