## Intentionality & Unit Overview

### Length of Unit: 5 Days

### Access each lesson from this unit using the navigation links below

Students will multiply fractions leveraging context and an area model.

## Intentionality…

The purpose of the Day 2 activities is to reinforce key concepts from Day 1. Students will engage in a string of related problems through a math talk and will have an opportunity to complete independent purposeful practice.

The math talk and purposeful practice serve to develop a deeper understanding of the following * big ideas*:

**Number:**

- Multiplication can be interpreted as “groups of” or “parts of”, where the first factor is the number of groups, and the second factor is the quota;
- Multiplication can be represented using an array or area model;
- A part of a whole unit can be expressed as a fraction;
- A fraction described the number of parts relative to a whole;
- The fractional unit (the denominator) communicates how the whole is partitioned (number of parts);
- Equivalent values can be represented by different fractional notation (for example, \(\frac{1}{4} \) is equal to \(\frac{3}{12} \));
- The product when multiplying fractions is relative to the whole unit.

## Related String Of Problems

Present the contexts below one at a time. Ask the students to model the context and solve.

There was half of a chocolate bar on the table. Layla ate one third of the remaining chocolate bar. How much of the chocolate bar did Layla eat?
