Notice and discuss the fractions in your child's world! When eating pizza or a pie, count the pieces of an eight piece pie, 1/8, 2/8, etc. Help your child cut their sandwich in half, fourths, thirds. Discuss with your child what part of the family they are: if you are one of six members of a family, you are 1/6th of the family. Let your child divide the dessert among your family members, i.e. if we have 5 brownies and four people, each person gets 1 and 1/4 of a brownie. Include your child in baking that asks for measurements that require fractions. Some books to read: "The Door Bell Rang" by Pat Hutchinson, "Eating Fractions" by Bruce McMillan, and the "Half Birthday Party" by Charlette Pomeranz.
If your child does not show an interest in fractions, wait until another time.
