# Lesson 6

All Kinds of Attributes (optional)

### Lesson Purpose

The purpose of this optional lesson is for students to use what they know about symmetry and parallel and perpendicular lines to complete or draw figures with those attributes on a grid.

### Lesson Narrative

This lesson is optional because it synthesizes all the sorting and classifying students have done up to this point. Grids are given here to encourage students to support students’ parallel lines, perpendicularity, and measurements and to support also thinking about attributes of figures. In upcoming lessons, students will use these lines of reasoning to solve problems about perimeter and angle measurements.

### Learning Goals

Teacher Facing

• Draw line symmetric figures and identify lines of symmetry.
• Identify two-dimensional figures using an understanding of parallelism and perpendicularity.

### Student Facing

• Let’s use what we know about attributes of figures to create drawings.

### Teacher Reflection Questions

How did you hear students use the vocabulary they have learned in previous lessons as they created and described shapes and figures in today's lesson? What can you do to encourage students to use geometric vocabulary in upcoming lessons and outside of math class?
