Why play this game?
This game will 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 his/her own or by up to three at once. If there are four, it would be more suitable to play two parallel games.
It could work well by introducing the game to just a few pairs or groups, one at a time. You could sit with the children and play with them until they understand what to do, in particular when they reach "9".
Once a pair understands the game you could give them the task of teaching others by playing with them.
A copy of the game, counters and dice could be made available for children to choose as an activity during appropriate times of the school day.
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.
