## Lesson: Fractions and Probability

Introducing the Concept

Before children learn to partition “wholes” into equal parts, talk about the concept of “fair shares.” Discuss with children when and why they share things that are the same size and shape. Guide them to connect the concepts of equal parts and fair shares.

**Materials:** drawing paper divided into four sections, crayons, three paper squares of the same size for each child, scissors

**Prerequisite Skills and Concepts:** Children should have an understanding of equal parts.

Direct children to draw a picture of themselves in the first section of the drawing paper. Ask them to draw a picture of a friend in the next section. Then give each child a square and ask him or her to pretend that it is a sandwich.
