More Practice with Percents - Practice Makes Perfect! - Section 2: Explore

My students thoroughly enjoyed today's game. I find that my two group reviews really bring out the mathematical conversation and reasoning between students.

In this particular case, I had a question regarding a markup. The students were given the marked up price, the mark up percent, and were asked for the cost to the store. I couldn't get my phone out in time to video the discussion, but it was awesome! Only one or two students in each group understood that they were looking for the original price - they struggle to wrap their brains around the concept of marking something up (not tax and tip, but rather marking up for profit). I had one student in my 4th block really go around and help her group - and in defending her answer she talked said "if we do it your way the store doesn't make any money, they lose money, so that doesn't make sense." I LOVE when kids realize the reasonableness of an answer. This type of question also made connections to the real world - which is key for student understanding. As soon as Elizabeth said - "the store won't make money your way," kids started listening to what she had to say.

# More Practice with Percents - Practice Makes Perfect!

Lesson 14 of 21

## Objective: Students will be able to solve a variety of percent application problems.

#### 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 identify the type of percent problem I am solving, and apply the correct procedures for solving it.” 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! **This concept lends itself to the use of **mathematical practices 2 and 4**, as most problems can be modeled using real world examples, and given those examples students have to reason both quantitatively and abstractly. Additionally, students are working with a decimal point - which can change the value of a number drastically if placed incorrectly, so it is important that students pay close attention to precision when working (**mathematical practice 6**).

#### Summary

*5 min*

**Instructional Strategy - Table Discussion: **To summarize this lesson, I am going to ask that students have a table discussion on what types of problems do we use division instead of multiplication? This activity will allow students the opportunity to have discussion on what we do when, and why. Students will experience success with this concept if they can identify what problems they are to work backwards on. I will have tables discuss, and then a representative from each table will share out.
