Introducing Geometry Review and Group Test - Section 2: Group Test

This year, I decided to incorporate some of the common errors I have seen in student work into the group test to really force students to discuss their ideas with each other. I think my favorite problem on the group test is problem #5e, which provides students with an isosceles triangle with vertex B and asks them to decide whether B is a midpoint. This particular problem forces students to attend to precision and to really critique each other’s reasoning, which gives them an opportunity to test what they understand.

# Introducing Geometry Review and Group Test

Lesson 7 of 8

## Objective: Students will be able to review for the test by working through review problems.

#### Stations

*50 min*

To accommodate different learning styles, I like to use Review Stations as a way to get students moving around the classroom. I encourage students to use their notes as they work and I let them choose whether they would like to work individually or with a partner. The goal is for students to visit several different stations and to do at least a couple of problems to get a sense of what they need to be able to do on the unit test.

I post an answer key at the front of the room so that students can check their work as they go along. While students work, I circulate the room to check in with the students who are struggling the most; I find that it is safe to do this since students are constantly moving and unaware of who is receiving special attention from me.

#### Group Test

*40 min*

I give a Group Test as a way to hold groups accountable for the learning they have done together. I give a few rules for the group test:

- Only one question is allowed for the group. When the group calls me over, I can ask any of the students what the question is--this ensures that the group checks in with each other and tries to solve problems on their own first.
- I will grade the group test by either choosing one test from the pile--the grade earned on this test will be given to each member of the group. Or, I will grade one problem from each person's test and total all the points--the total score is the same for each member of the group.

I find that group tests really encourage discussion and invite peers to review each other's work and to give feedback, especially because of how the tests will be graded. Additionally, group tests provide students the opportunity to review together for the individual test.

Hello, in your group test, you reference a #5e, which I assume must be on the second page. But I only see one page on the PDF. Could you post that, please? Thanks!
