Lesson objective: Solve division problems involving grams, liters, and kilograms.

This lesson provides an opportunity for students to apply their knowledge and understanding of division to a mathematical situation. Students are asked to help figure out which box is which after an order form gets smudges on it.

Key Concept students will use:

- We can use division to solve problems involving measurement quantities (including liquid volumes and masses of objects).

Skills students will use:

- Using arrays for foundations for multiplication (Grade 2, Unit 13)
- Exploring equal groups as a foundation for multiplication and division (Grade 3, Unit 1)
- Understanding the relationship between multiplication and division (Grade 3, Unit 7)
- Developing strategies for multiplication and division (Grade 3, Unit 9)

Students engage in Mathematical Practice 4 (Model with mathematics) as they with model the math using multiple strategies like tape diagrams, number lines and equations.

**Key vocabulary: **

- division
- grams (g)
- kilogram (kg)
- liter (L)
