Do choose worksheets that are appropriate for the childs level, since children can get discouraged easily, if they are unable to perform the activity. Well illustrated worksheets with cartoons are also more likely to appeal to children. Worksheets that use common situations children come across at home, school, in the market place etc and that use common objects known to children would be more relevant.
One activity that is a wonderful math lesson for preschoolers is called "A New Kind of Basket Ball". For this activity, line up five baskets or bins in front of the children and label them with the numbers one through five. These number labels should not only have the written number digit, it should also have dots that represent the corresponding number. Place fifteen balls in front of the children as well. Ask them to put the right amount of balls into each basket; one ball should be in the basket with the number one on it and so on. This activity teaches math appropriately to preschoolers. Children not only need to experience math with concrete objects but also visually and symbolically through abstract activities. The concrete objects in this activity are the balls. The balls represent materials that the children can see and touch and use to visualize and verbalize their thoughts. The number labels on the baskets represent visualization. The children should be given illustrations or pictures that represent the concept you are teaching them. The dot on the number one card, two dots on the number two card, and so on, illustrates each number for the children. The dots also represent the symbol of the numbers they are working with.
