You can use these slides in many different ways. With my group I played a game. Here are the steps in case you want to play a game with your kids as well: 1.Divide the class into groups. Decide the order the groups will play. 2.Show the first slide to the first group. If the answer is correct, they can throw a dice. The number on the dice indicates the number of points they will get! 3.Show the second slide to the second group and so on.
