MATH POWER: Partition Shapes Into Halves, Thirds, and Fourths
40 MIN
Introduce In this lesson, campers will partition circles and rectangles into equal parts and describe the parts as halves, thirds, and fourths. Distribute classroom materials and Worksheets 1 and 2 to campers. Campers, have you ever shared food by splitting a whole into smaller parts? Give campers a moment to respond, then continue. Pizza is a kind of food that is already split into smaller pieces. Each slice is an equal part of the pizza. Can you think of any other foods that are already split into equal parts? Can you remember a time when you had to split food into equal parts yourself? Invite campers to share their experiences with the class. Inspire
Introduce Introduces the math concept from the lesson.
Two friends want to share their snacks. One friend has a granola bar. The other friend has a slice of watermelon. Look at the illustrations of the granola bar and watermelon on Worksheet 1. What do you notice about the granola bar and the watermelon? What do you wonder?
Inspire Gets campers thinking about questions we can ask about that week’s math topic.
MULTILINGUAL LEARNERS Ask: What shape is the granola bar? Watermelon slice? How can you show splitting a shape? What does it mean to share a snack “equally”? Challenge campers to come up with at least one clarifying question they can ask.
Give campers a few moments to think. Then have them turn and talk with a partner. Give partners a few moments to discuss. Invite campers to share their noticings and wonderings. Encourage them to model belonging by listening respectfully, contributing to the conversation, and being open and accepting of other campers’ contributions. If campers do not mention cutting each snack into smaller, equal-sized pieces, ask these guiding questions to spark their thinking: What is the shape of each snack? How many people need to share each snack? Then explain that in this activity campers will split shapes into equal parts and name the parts. Investigate Guide campers to Problem 1 on Worksheet 1.
Investigate Campers work together to investigate the problems and use strategies to solve it.
RANGE OF LEARNERS Increase Access Place a plastic sleeve over the worksheet. Have campers use a dry-erase marker to try out partitions. Encourage campers to redraw as needed. Increase Challenge For additional challenge, have campers show at least two different ways to partition each snack. Have them tell which way(s) they like best and why.
Let’s explore some math skills together! We can split up, or partition, a snack into smaller pieces to share it. Campers, why might we want to partition the snacks into equal parts? Give campers a moment to respond, then continue. Most people think that equal-sized pieces is the fairest way to share. The first questions we want to answer are: How can each snack be shared equally by two people? What part is each share? Take some time on your own to think about how we might partition
