Unit 3, Lesson 6
Problems with Equal Groups of Fractions
Grade 4
Preparation
Lesson Narrative
Students may choose to draw diagrams, write equations, or make use of patterns to understand the situations and answer the questions. As students make sense of representations and quantities in context, they practice reasoning quantitatively and abstractly (MP2).
- Engagement
- MLR7
- Explain (orally) strategies for solving problems involving multiplication of a fraction and a whole number.
- Represent situations involving multiplication of a fraction and a whole number, with expressions.
- Let’s solve problems with fractions.
Required Materials
Activity 2
Required Preparation
-
Write the 5 expressions from the activity on separate posters and post them around the room:
Extend the lesson by engaging students in a discussion about where the food that people eat comes from. Ask students to identify the source—animal, plant, or mineral—of each ingredient featured in Activity 1, “Banana Bread Recipe.” (You may need to explain that baking soda is made from compounds found in rocks.)
- banana (plant)
- butter (animal)
- baking soda (mineral)
- sugar (plant)
- eggs (animal)
- flour (plant)

Teacher Reflection Questions
What new mathematical connections did you see students make today as they were solving problems about multiplication of fractions? How can those connections be leveraged in upcoming work?
