Egg Ratios
Essential Question
What are ratios and how can they be used to compare quantities effectively in real-world situations?
Grade(s):
- 6
Subject(s):
Recommended Technology:
Other Instructional Materials or Notes:
Materials: 2 dozen plastic eggs, egg fillers (optional)
Preparation: Print out copies of egg ratio recording sheet. Seat students in groups of 6. At each table, place 6 eggs in a basket or container.
Lesson Progression
1. "Hide" eggs around the classroom. as students enter in, instruct them to find one egg and take it with them to their seats.
2. Introduce a ratio as something that compares two quantities. Hold up 1 red egg and 2 blue eggs. Record the ratio 1:2 on the board. Ask students what each number represents.
3. Ask the students what the ratio of red eggs to total eggs would be (1:3). Repeat this same investigation once more with green, yellow, and purple eggs.
4. Explain to students that the value of a ratio is simply dividing the first quantity by the second quantity. This can be written as a fraction. Complete an example as a class.
5. Give students recording sheets and have them work in groups of 6 to complete.
Teacher Notes
Differentiation: Pull students for small group remediation as necessary. Work with smaller, single digit numbers prior to increasing to the double digits. Stick with ratio values less than one. Manipulate groups of eggs and have students record numerically.
Extension: Give each student an increased number of eggs. Have students create real world scenarios to match found ratios.
