UNIT PLAN
Crunch the Numbers

# Snack Time

In Lesson 1 below, students crunch the numbers by practicing critical math operations, and find out how they can stay fueled to learn by making smart fruit & veggie snack choices.

OBJECTIVE

Students will learn to add and subtract two- and three-digit numbers; and understand that fruits and vegetables are healthy options for a snack.

MATERIALS

SET UP AND PREPARE
Time Required: One 40-minute class

DIRECTIONS

1. Review the place values of two- and three- digit numbers. Ask: In the number 123, what does the 1 digit represent in the hundreds place? (100) What about the 2? (20) And the 3? (3) Remind students that the value of each digit depends on what place it’s in.
2. Next, review rules about adding and subtracting two- and three-digit numbers, including carrying and borrowing tens.
3. Explain to students that just like in adding numbers, eating healthy foods like fruits and vegetables adds up to a whole, healthy person. Eating fewer healthy foods subtracts from our good health. When we reach for a healthy snack, we are making a choice to add nutrients to our bodies. Nutrients provide us with energy and help build or repair parts of our body. Because our bodies cannot make all the nutrients we need to be healthy, we get important nutrients from the food we eat.
4. Make copies and distribute Worksheet 1: Snack Time (PDF). Have students complete the activity, then work on their “More Is Better” goal.
