Formative Assessment Day 1 - Section 2: Formative Assessment and Feedback

In this age of texting and tweeting, the rules of precise notation have really relaxed. In a geometry course, though, I can't really allow this to happen. In the following video, you'll get an idea of some of the common mistakes that I want to nip in the butt before they reach the level of "i", "ur", "k" and all the rest.

# Formative Assessment Day 1

Lesson 6 of 14

## Objective: Assess student mastery of points, lines, rays, planes, segments, midpoint, and distance

#### Independent Practice

*25 min*

During this section, students are working silently on Formative Assessment 1. Students will have 25 minutes to complete the assessment.

When the time elapses, I allow students to keep their papers so that they can get immediate feedback on their own work.

#### Resources

Now that students have completed the assessment, I go over each item on the assessment. Students have mini whiteboards and markers. For each item I do the following:

- Have students copy their responses from their paper onto the mini whiteboard.
- Survey the whiteboards to roughly determine the percent correct and the common errors and misconceptions
- Do a think-out-loud as I show the correct answer.
- Discuss common misconceptions and mistakes, if necessary.

When we've completed all items, students write a reflection on their overall performance on the assessment. They identify their areas of strength and the areas in which they need to improve. At the end of the lesson, I collect the assessment papers and the reflections.
