Teach counting songs with catchy rhymes to help your child recognize numbers. Because young children learn from games involving singing and movement, songs and rhymes are good tools for preschool or kindergarten-aged students.
Play games with items that help them visualize mathematical problems. So-called manipulatives are helpful for all age groups, and are particularly useful in teaching younger children about addition, subtraction and division.
Find online math games you can play with your child. Many websites divide games and exercises according to age groups, skills and grade levels.
Devise games you can play with your child while grocery shopping. Count out apples or potatoes as you place them in your basket. Demonstrate subtraction with the change you receive from your payment.
Teach math concepts through cooking. Use measuring cups to explain fractions.
Hire a tutor or older student to help your child if you don't understand or no longer remember certain concepts. Your local schools might be happy to match your child with a student who in turn would benefit from teaching math to a younger child.
