# Working Backward with Percent: Practice Makes Perfect!

Lesson 12 of 21

## Objective: Students will be able to identify the unknown value in a percent problem and apply the correct procedures for solving for that unknown.

#### Launch

*10 min*

**Opener: **As students enter the room, they will immediately pick up and begin working on the opener –Instructional Strategy - Process for openers. This method of working and going over the opener lends itself to allow students to construct viable arguments and critique the reasoning of others, which is **mathematical practice 3**.

**Learning Target: **After completion of the opener, I will address the day’s learning targets to the students. For today’s lesson, the intended target is, “I can determine the unknown value in a percent problem and apply the correct procedures to solve for that unknown.” Students will jot the learning target down in their agendas (our version of a student planner, there is a place to write the learning target for every day).

**Thoughts from Me! **As students begin to work on problems, they will be looking for patterns and/or repeated reasoning (**mathematical practices 7 and 8**). What types of problems require division? Students will need to be precise when determining the information they are given so that they are able to accurately find the missing value (**mathematical practice 6**).

**Homework: **Since student pairs will finish the scavenger hunts at different times, I have placed the homework assignment on the back of the scavenger hunt paper. Thus, as students finish the activity, I will quickly check their paper, and then send them to their seats to work on the homework assignment. I wouldn't want the students to be bored... :)

#### Summary

*5 min*

**Instructional Strategy - Table Discussion: **To summarize this lesson, I am going to ask students to discuss at their tables clues that they find in a problem that helps them determine if they are given the new or the original value. I will choose three tables to share out at random by drawing playing cards.
