## Lesson: Fractions and Wholes

Introducing the Concept

Begin by giving children opportunities to practice identifying and using fractions. Have children practice coloring given parts of shapes and then identifying what fraction of each shape is colored and not colored. Offer different types of shapes divided into different numbers of parts to give children practice with many different fractions. Encourage them to use fractions in their conversation and class discussion. Have children practice looking at groups of different shapes and identifying, for example, what fraction of the group are circles. Provide enough experiences that children feel comfortable talking about and identifying simple fractions and recognizing how fractions are written.

**Materials:** set of solid shapes including 3 spheres, 4 cubes, 1 cylinder, 2 cones, and 2 rectangular prisms; two blank color wheels for each child—one divided into fourths, one into sixths; red, blue, yellow, and green crayons for each child

**Preparation:** Arrange solid shapes in a 3-across-by-4-down arrangement. Do not place all like shapes together. Prepare and cut out blank (uncolored) color wheels as indicated above.

**Prerequisite Skills and Concepts:** Children should be familiar with the names of solid shapes and with the concept of fractions. Children should also have practiced methods of identifying fractional parts.
