Welcome! In this module focus session, we will examine Grade 3 – Module 4. This is an exciting and interesting unit because it provides a nice application of Modules 1 and 3 as students learn about area concepts.

2 Grade 3 – Module 4 Module Focus Session
November, 2013 Network Team Institute TIME ALLOTTED FOR THIS SLIDE: 1 minute MATERIALS NEEDED: X Session Objective Prepare to implement Module 4 by examining mathematical models and instructional strategies in the lessons. The objective for this session is to help you prepare to implement Module 4 by examining the mathematical models and instructional strategies in the lessons. To achieve this objective, we’ll be looking at the specific models used within each Topic to see how it moves the learning forward.

3 Curriculum Overview of A Story of Units
Grade 3 – Module 4 Module Focus Session November, 2013 Network Team Institute TIME ALLOTTED FOR THIS SLIDE: 1 minute MATERIALS NEEDED: X Curriculum Overview of A Story of Units The fourth module in Grade 3 is Multiplication and Area. The module includes 16 lessons and is allotted 20 instructional days. This module builds on understandings established in Modules 1 and 3 with multiplication and division and creates authentic contexts for relating these prior understandings. It seeks to build a conceptual understanding of area through the lens of multiplication instead of merely establishing the “formula” for area.

4 Grade 3 – Module 4 Module Focus Session
November, 2013 Network Team Institute TIME ALLOTTED FOR THIS SLIDE: 7 minutes MATERIALS NEEDED: M4 Overview Narrative Read the descriptive narrative and underline key phrases. Summarize the major learnings of the modules in 1-2 sentences. In Module 4, students explore area and relate it to their prior understanding of multiplication. As you read the module overview, hopefully you will see how the concepts from Modules 1 and 3 are used to support the students’ understanding of area. Take a few minutes to read the Module Overview. As you read, highlight key phrases that help build a picture of what the learning in this Module will look like. After you finish reading, gather your thoughts by jotting down 1-2 sentences that summarize the major learning of the module. (Allow 1 minute for jotting.) Turn and talk with others at your table. Share observations about what is new or different to you about the way these concepts are presented. (Allow 2 minutes for discussion.)

5 Moving Towards the Area Model
Grade 3 – Module 4 Module Focus Session November, 2013 Network Team Institute TIME ALLOTTED FOR THIS SLIDE: 1 minute MATERIALS NEEDED: X Moving Towards the Area Model This model shows how students will progress from using arrays in Modules 1 and 3 to using the area model in Module 4. Turn and talk to a partner about how this model shows the progression from arrays to the area model. Module Overview, Terminology: New or Recently Introduced Terms

6 End-of-Module Assessment
Grade 3 – Module 4 Module Focus Session November, 2013 Network Team Institute TIME ALLOTTED FOR THIS SLIDE: 6 minutes MATERIALS NEEDED: G3-M4-End-of-Module Assessment End-of-Module Assessment What concepts will students need to master by the end of the module? Now that you know the focus of the module, let’s see how students are assessed on their mastery. Take a look at the problems on the end-of-module assessment. Talk to your neighbor, what concepts will students need to master by the end of the module? What do you find interesting or surprising? Keep these problems in mind as we look at the models in the module and see how it builds up to the students’ level of mastery.

7 Grade 3 – Module 4 Module Focus Session
November, 2013 Network Team Institute TIME ALLOTTED FOR THIS SLIDE: 5 minutes MATERIALS NEEDED: Presenter Problem Set and pattern blocks (for presenter) Topic A Foundations for Understanding Area Topic A provides foundations for understanding area. Students use a variety of manipulatives to concretely support their understanding of area as the amount of space that a two-dimensional figure takes up. Note to presenter: Use the document camera and Problem 1 from Lesson 1’s Problem Set to show how the concept of area is established. Use triangle pattern blocks to cover Shapes A and B and discuss how each shape is covered by the same number of green triangles. Then use Problem 5 from Lesson 1’s Problem Set to show how square units are established as a unit to measure area. Use square pattern blocks to cover the rectangle and discuss how we say the area of the rectangle is 6 square units. Why do we call them square units? Why do we use square units?

8 Grade 3 – Module 4 Module Focus Session
November, 2013 Network Team Institute TIME ALLOTTED FOR THIS SLIDE: 2 minutes MATERIALS NEEDED: X Students start Lesson 2 with a 1” by 12” strip of paper. They use their ruler to mark each inch along the top and bottom of the strip. Then they connect the marks as shown. Finally, they cut the strip along the lines they’ve drawn. These tiles are used to establish the square inch as a unit to measure area. Students discuss the difference between square units and square inches. They repeat this process with a 1 cm by 12 cm paper strip. T: Since the sides of the squares each measure 1 inch, we call one of these squares a square inch. What is the area of your paper strip in square inches? S: 12 square inches! T: Did the number of squares change? S: No. T: Talk to a partner. What changed about the way we talked about the area of the paper strip? S: The units changed.  Before we called them square units, but now we can call them square inches because all 4 sides measure 1 inch.  We named this square unit. A square unit could have sides of any length. A square inch is always the same thing. Lesson 2, Concept Development

9 Grade 3 – Module 4 Module Focus Session
November, 2013 Network Team Institute TIME ALLOTTED FOR THIS SLIDE: 4 minutes MATERIALS NEEDED: Square inch tiles (1 bag per pair) and Selected Problem Set Work with a partner to use the square inch tiles to create 3 rectangles (as outlined in script below). Estimate to draw each rectangle in the chart on your Problem Set. Bags of the square inch units (for each pair) on tables after lunch. T: Now arrange all 12 squares into 2 equal rows. Remember, the squares have to touch but can’t overlap. T: Draw your rectangle in the chart for Problem 1. What is the area of the rectangle? S: 12 square inches. T: Record the area. You can record it by writing 12 square inches, or you can write 12 sq in. T: Rearrange all 12 squares into 3 equal rows to make a new rectangle. Draw it in the chart and record the area. At my signal, whisper the area of your rectangle to a partner. (Signal.) T: Rearrange all 12 squares into 4 equal rows to make a new rectangle. Draw it in the chart and record the area.
