## Angles Unit Test - Section 2: Angles Unit Test

# Angles Unit Assessment

Lesson 6 of 6

## Objective: Students will be able to solve problems and justify their reasoning by applying their understanding of vertical pairs, linear pairs, corresponding, and alternate interior angles.

I use this Warm-Up because it provides students with extensive angle relationships review. In the first problem, students solve for angles and use their solutions to answer a bigger question: what kinds of special quadrilaterals can they identify by their angle properties?

The third question gives students additional practice with applying angle relationships on parallel lines, and the fourth question asks students to write a proof to show the alternate exterior angles in the diagram are congruent.

I give more time than usual for this Warm-Up because it is students' last opportunity to review before taking the assessment. I circulate the room while students work to make sure that their questions are answered. I have student volunteers present the answers to the Warm-Up, emphasizing that taking the risk to present really gives them the chance to test their thinking and to get feedback.

#### Angles Unit Test

*60 min*

The test features a variety of fill in the blank, true/false, and multiple choice problems to test students' foundational understanding of angle relationships. There are several problems for which students need to apply angle relationships to solve for variables or angles (**MP1**).

On problems 10, 12, and 14, students focus on justifying their reasoning. On these problems, students must explicitly state the given information and then show how they have used that information to draw logical conclusions (**MP3 **and **MP6**).

When I return this test to students, I explain Mastery Reform [details in this video], which is a process that allows them to learn from the mistakes they made on the assessment to then demonstrate deeper understanding about the concept.
