Teach your child to count. Frequently, sing songs and recite rhymes that feature numbers or emphasize counting, like "One, Two, Buckle My Shoe" or "Ten in the Bed." While interacting with the children during the day, make counting aloud a habit. When taking a walk with your child, count how many steps it takes to get to the sliding board, or count the number of forks being passed out at dinner.
Work on number recognition with them. Read number picture books to your child, so she can see the numbers, as well as the equivalent number of objects. Point out numbers in their environment. Show children numbers on signs, clocks, mailboxes and houses. Find numbers in books, on toys and in stores.
Practice sorting objects with children. For example, gather up some blue socks and white socks. Have children put the white socks in a pile and the blue socks in another pile. Tell them to count the white socks. Then count the blue socks. Have them add the white socks to the blue socks pile and count the total number of socks they have. Repeat this activity with different types of objects.
Give children five apples. Tell them to put a certain number of apples in a bowl. Ask them to count how many apples are not in the bowl. Repeat this activity with different objects like crayons and balls.
