Product Description
This lesson is to introduce tax and tip. 7th grade. I did it with my students and they loved it. I was observed by my supervisor and she loved it. This may be a lesson that can roll over to a second day.
PLEASE NOTE THAT THE PREVIEW IS THE ENTIRE POWERPOINT PRESENTATION WHICH YOU WILL NEED TO DOWLOAD FOR THIS LESSON. WHEN YOU PURCHASE THE ITEM YOU WILL BE ABLE TO DOWLOAD THE WORKSHEET FOR THE STUDENTS.

First, ask students to raise their hand if they've been to a restaurant where a waiter brings over their food recently. Show them the picture on the second slide of the receipt to tell them that they will bring over the bill, but what if it's only two people and bill is \$100. That is the hook. Wouldn't they want to know why they are being charged so much. Tell them "today we're going to learn about how to calculate tax and tip to make sure that you don't ever get over charged or ripped off at a restaurant." If your parents are paying, then you can be the expert.

First teacher models how to turn a percent into a decimal and students copy in their notes. Teacher then can do a rally coach where pairs of students go back and forth reading each percent on the projector screen = the decimal. This is a way for students to remember how to turn a percent to a decimal. Teacher can call on random students to read outloud to the class. Remind them that they will need this skill to find the tax and tip.

Teacher will have a volunteer student pass out small cups and serve orange juice halfway to ensure that it doesn't spill. Teacher will tell students "Welcome to Mr./Ms.______(your name)___ restaurant and show the powerpoint slide with the pictures and prices on the menu. Remind them that you just served them the first item on the menu. They will be very excited at this point.

Teacher will also have students pass out the worksheet (you download once purchased). The first question is very appealing. It has a picture of the orange juice and a blank for you to fill in the number of students in the class who got orange juice. "The how much will _____ pay" is for you to choose a random student in the class who will pay the bill. This will get them excited, because they think they will pay for reals. Teacher will asks students how we calculate the total before tax if each cup is \$1.50. They will all say "multiply" Teacher will then model how to obtain the tax on the amount on q.1. and then a 9% tax. Then a 15% tip. In the end, restate, that _______ student will pay this much money with tax and tip. The students will be really shocked to see how much more money the bill comes out with tax and tip.

Ask the students to pair share the steps to obtaining the tax and then the tip. Have them do question 4 on their own. Keep the sheet with the example displayed on the projector. As a random student how to solve question 4. Then have them do question #5 and then pair share. After pair share call another random student to explain how to solve question #5. Model on the worksheet as they explain. You might have to do the tip question and model again in case they still don't get it. Let them do the back portion on their own or with their partner. Give them an exit ticket at the end of the lesson.

This lesson may take two classes to do. YOU CAN EDIT MS. ORTIZ and put your name.
