__**Title: Complementary and Supplementary Angles - Day 1 **__ 2 Days
 * Author: **Lynne Wilde
 * Subject: **Math
 * Grade Level(s): **6–8 **Duration: **

Students will learn to classify pairs of angles as complementary or supplementary based on the sum of their measures.
 * Unit Description**

Introduce students to basic geometric properties of complementary and supplementary angles.
 * Lesson Description for Day**

(6) Geometry and spatial reasoning. The student compares and classifies two- and three-dimensional figures using geometric vocabulary and properties. The student is expected to: (A) use angle measurements to classify pairs of angles as complementary or supplementary;
 * State Standards**

Students will be able to identify, complementary and supplementary angles based on the sum of their measures.
 * Goals Unit Goals: **

All students will know that complementary angles are equal to 90° and supplementary angles are equal to 180°.
 * Lesson Goals:**

**Anticipatory Set:** Introduce the class to complementary and supplementary angles by reading digital book Angles All Around, and by discussing and locating the angles included in the book's images.
 * Methods**

Students will be asked to give other examples of angles from objects within the classroom. (Activity is recognition and affective)  Explain to the students that they will be learning about the geometric properties of two types of angles.
 * Introduce and Model New Knowledge: **

Introduce key vocabulary - complementary angle and suplementary angle Show video explanation of complementary and supplementary angles from Khan Academy.

<span style="font-family: Arial,Arial;"> (Activity is recognition and strategic)

<span style="font-family: Arial,Arial;">**Provide Guided Practice:** <span style="font-family: Arial,Arial;">Project SmartBoard lesson - Complementary and Supplementary Angles.

Allow students to take turns coming to the SmartBoard to classify angles. <span style="font-family: Arial,Arial;">﻿ (Activity is strategic and affective)

<span style="font-family: Arial,Arial;">**Provide Independent Practice:** <span style="font-family: Arial,Arial;">Students will be asked to classify 12 different pairs of supplementary or complementary angles based on their value. (Activity is strategic)

<span style="font-family: Arial,Arial;">End today's lesson with by reviewing the properties of complementary angles and supplementary angles. Answer any question and clarify any questions brought up by students. (Activity is recognition and affective)
 * Wrap-Up**

Observation during discussion and guided practice will be used as formative assessment.
