| Learning Context:
(This lesson is designed for a unit on Percents and Proportions.) OBJECTIVE: Students will be able to demonstrate an understanding of tax, discount, and commission by problem solving with a simple equation. MODELING: Subobjective #1 *Students will be able to define tax, discount, and commission. Information- *TAX: amount added to the regular price of something *DISCOUNT: amount the regular price is reduced *COMMISSION: amount given to an agent for the service of selling a product Strategy- *Have students think of definition then share it with their study partner. *The teacher will then survey the responses. Subobjective #2 *Students will be able to use the simple equation to problem solve. Information- *The equation: Original*Percent of Change = Amount *Two methods: 1. Using two steps 2. Using one step Strategy- *Model, check for understanding, guided and independent practice. LEARNING STANDARDS: ELA #1,4 CDOS #1 MST #1,2,3 |
| Procedure:
ANTICIPATORY SET: After Mr. and Mrs. Zigrossi moved into their new house, they had to buy some dining room furniture. They went into a popular furniture store in the area and were very surprised by the customer service they encountered. A man named Louie approached them and asked what they were looking for. When they said that they were just looking, he handed them a card and repeated his name several times. Why do you think he did this? Tell your response to your study partner. (Answer: Louie worked on commission.) CHECKING FOR UNDERSTANDING: 1. Tell your partner how you would find the price of a $35 sweater on sale at 20% off. 2. Compare and contrast sales price and discount. 3. Write an equation to find the amount of money you will pay for a SONY Playstation game for $35.99 that is taxed 8%. GUIDED PRACTICE: 1. Each student will be assigned to a differential group based on readiness. 2. Each group will have a real-life theme and will contain problems based on tax, discount, and commission. 3. Once in groups, students will choose a role (facilitator, checker, note-taker or encourager) and will work together to solve each problem. 4. The teacher will collect one lesson from each group to assess their work. 5. The students will then log on to the CareerZone website. 6. Students will continue their roles, however, the checker will become the reader and the encourager will become the typist. 7. Each group will access a career that relates to their theme and read the description given by the website. 8. The students will then individually write a short summary of the career highlighting if and how mathematics is used. 9. Following the computer activity, the groups will be rearranged so that the new groups will contain one student from each career. 10. The students will then do a Round Robin sharing technique to report their findings. CLOSURE: Students will be asked to reflect on the lesson and using their SCANS skills sheets, identify skills they used during the lesson. INDEPENDENT PRACTICE: Worksheet #46 |
