# Markup Percent Models - Percents Over 100?

Lesson 3 of 21

## Objective: Students will be able to calculate markups using a percent bar model.

## Big Idea: What is a tip or a markup? Conceptual understanding of markups are key to understanding - by using a bar model students are able to deepen their understanding.

**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 calculate a markup using a percent bar model.” 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 a way to dive into percents and create a conceptual understanding, students will utilize a bar model (**mathematical practice 5**). They will use the model to represent scenarios conceptually (**mathematical practice 4**) instead of just punching numbers. Students will also reason abstractly and quantitatively by analyzing what each model represents (**mathematical practice 2**). Students will look for repeated reasoning to make connections within percents (**mathematical practice 8**).

#### Summary + Homework

*5 min*

**Instructional Strategy - Table Discussion: **To summarize this lesson, I will have students have a table discussion on: How much would my total bill be if it is $20 before I leave a 10% tip? The purpose of this table discussion is again to get students thinking about mental percents – and applying their thinking to real world situations. Calculating a tip or tax is something that all kids will do in their life – and it is important that they know how. I want students to think through the process of the bar model without having to use it. I will have each table share out their thinking so that all tables can see how the problem can be solved.

**Homework: **After the table discussion, I will pass out a 5 question homework assignment for students to put all of their skills together. The assignment mixes mark ups, mark downs, and percent of a number - a good way to check for understanding.
