### Topic 11: Properties of Two-Dimensional Figures

Note: The original dates you set for this unit was January 6-16 (Jan 17 posttest/pretest). However, most of you will be starting this unit soon since your pacing is determined by student understanding.

### Tip of the Week:

- There is a lot of new vocabulary during this unit; therefore, making connections to vocabulary are extremely important. Click here to view some ideas for integrating technology with vocabulary. It can be used as a center activity in math. For some students, you may even ask the home room teacher if there is any time your student could substitute something (such as the morning wake up review) to spend extra time with vocabulary.
- Kim Sutton also has vocabulary ideas too.

### Technology Integration Resources:

- Interactive Geometry 3D Shapes
- Isometric Drawing Tool on NCTM’s Illuminations: Special quadrilaterals include rectangles, squares, parallelograms, trapezoids, rhombi, and kites. Students can use tools such as the Isometric Drawing Tool on NCTM’s Illuminations site to shift, rotate, color, decompose and view figures in 2D or 3D. Note: This will not work on our netbooks because it requires java.

### Mathematical Practices:

When students share their thinking and reasoning about the solutions, they are justifying their solutions (DOK 3), a foundational critical-reasoning skill. The ability to articulate a clear explanation for a process and critique the reasoning of others is the backbone of **Math Practice #3**—*Construct viable arguments and critique the reasoning of others*.

Some question stems for **MP.3** are:

- What strategy will you try to solve …? How did you decide to try that strategy?
- How did you decide what the problem was asking you to find? (What was unknown?)
- Did you try a strategy that did not work? Why didn’t it work? When would it work?
- How could you demonstrate a counter-example?

Have you thought about having the students solve a problem and capture their thought process on an iPad? Then have students pass the iPad to another group to listen and critique their explanation?
