Count with your child. Look for things to count and count them aloud with your toddler. You can count her toes, her fingers, building blocks and books. Remember to tell your toddler the name of the item you are counting so she learns what different items are called.
Play rhyming games with your child. Recite rhymes or song lyrics that contain number concepts and themes. For example, "This Little Piggy" and "Five Little Monkeys" are frequently used children's poems that incorporate counting. Your child will not only enjoy the rhyming sounds, but also will learn addition and subtraction concepts.
Use vocabulary that demonstrates mathematical importance. For example, use phrases like "a lot," "a few," "a little smaller," and "a little bigger." Your child will begin to understand the concept of sizes and group numbers through repetition and constantly hearing these phrases used in different situations.
Teach your child her shapes. Most toddlers will not sit still long enough to be interested in shape flash cards, so find shapes around the house that your child can help you identify. Use a ball to talk about circles and compare it with the circle shape of a dinner place. Select a book to show your child the shape of a rectangle and compare it with a DVD case.
