A Rainbow of Fruits & Vegetables

In Lesson 2 below, students feed their minds by learning fractions and percents, then learn to feed their bodies for school and play by eating a rainbow of fruits and vegetables.

OBJECTIVE

Students will learn to use a pie chart to identify and add fractions and percents; and understand that antioxidants exist within colorful fruits and vegetables.

MATERIALS

DIRECTIONS

1. Explain to students how to compare fractions using pie charts. On the board, draw three pie charts divided into 2, 4, and 12 equal parts. Color in one piece in each chart and ask students to name each fraction. Then color in pieces on all three charts to represent 1/2, 2/4, and 6/12. Ask: What fraction of each circle did I color?
2. Next, review equivalent forms of fractions (and/or percents). As an example, ask students to try to remember how many differently colored fruits and vegetables they ate yesterday, then to describe how many of each color they ate as a fraction (or percentage) of the total.
3. Explain to students that colorful fruits and vegetables contain special nutrients called antioxidants. Antioxidants (such as beta-carotene, found in orange fruits and vegetables) may help protect a number of one’s organs and body tissues from wearing out.
4. Make copies and distribute Worksheet 2: A Rainbow of Fruits & Vegetables (PDF). Have students complete the activity, then work on their “More Is Better” goal.
