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.
There are many good workbooks available for kindergarten children. However with a regular workbook, a child can do each activity or worksheet only once. A good option is to use printable kindergarten worksheets. These are basically digital versions (like ebooks) of worksheets that can be bought and downloaded to your computer from the internet or from CDs and then printed out. The advantage is that you can print out whichever sheet you wish. If you need to re-inforce a certain concept more you can usually print out that sheet again. Of course you will therefore need to have a computer and a printer.
Here are a few ideas for such activities: The alphabet song: This remains a lovely way to practise the alphabet. Sing it slowly and sing it often. If you have a large alphabet chart and point out to each letter while you sing, it will be of great value. You can give all children letter cards in order (alphabet flashcards); they can hold up each letter as it is sung. Show a magazine or picture book to children. Ask them to identify all instances of the given letter in any page. Hand out letter cards to all children. Call out a letter. The child with that card has to come in front of the class and display the letter. Divide the class into two groups. Give one group letter cards. Give other group various objects. The first group will hold up a letter. The second group should hold up an object that starts with that letter.
