SWBAT solve problems involving tips and markups

Can you leave a tip?

5 minutes

**POD**

As students enter the room, they will have a seat, take out their **Problem of the Day** (POD) sheet and begin to work on the question on the SMARTboard. The POD allows students to use **MP 3** continually based on the discussions we have about the problem each day.

**Learning Target**

The target for the day is also on the SMARTboard each day when students enter the room. The target for today’s lesson is for students to simplify expressions they are given.

Having done work with sales tax, students are familiar with finding the sales tax and total cost of an item. I want to introduce them to the idea of leaving a tip and finding the amount of markup. To start the discussion, the POD today will be to identify what my students already know about tips and markups.

If it costs Nike about $16 to make one pair of Air Jordans and the shoes cost about $190 before tax, what percent increase is this? What is this increase called?

What is the difference between a tip and a markup? Are there differences between the way to find a tip and a markup?

30 minutes

To explore the differences and similarities between tips and markups, I will show students several examples of problem situations to continue discussion about tips, markups, and the ways to find amounts associated with both. As we walk through the examples, discussion will center around how students know and what they know about finding a tip. I am anticipating a rich discussion about why tips are important and how markup applies to business.

The exit ticket will have students describe the process for finding a markup amount. I want to determine what they know and understand. I can use the exit ticket as a formative assessment to help decide where to go with the next lesson. Are students ready to move on or do we need to spend more time developing the concept?

Describe how to find the selling price of a pair of jeans that cost $12 with a 76% markup. What steps will you take?
