Unit 3, Lesson 20
Sticky Notes (Optional)
Grade 4
Preparation
Lesson Purpose
The purpose of this lesson is for students to apply their understanding of multiplication of a whole number by a fraction to create sticky-note letter designs.
Lesson Narrative
This lesson is optional because it does not address any new mathematical content standards. This lesson does provide students with an opportunity to apply precursor skills of mathematical modeling (MP4). In previous lessons, students used diagrams, expressions, and equations to represent multiplication of a fraction by a whole number.
In this lesson, students apply their knowledge of multiplying a fraction by a whole number to create sticky-note designs. They create a design given a set of constraints. Students describe their design to others before gaining access to the supplies to make their design.
- Action and Expression
- MLR8
- Ask (orally) questions to gather information to improve an estimate.
- Create a design that follows constraints, based on lengths that include fractions.
- Let’s make a design using sticky notes.
Required Preparation
Activity 1
- Gather rectangular sticky notes with fractional lengths. If this is not possible, then cut from cardstock rectangles with fractional lengths.
Activity 2
- Each student will need a blank piece of paper and enough sticky notes with fractional side lengths to complete their design.
Teacher Reflection Questions
How comfortable were students in making choices? Were your students able to explain their thinking and convince others that their design fit the given constraints?
