TEKS Based Lesson Plan

North East Independent School District

Subject: Math Models Weeks: 2nd Nine Weeks Group 2

Unit of Study: Quadratic Functions and Exponential Growth & Decay Essential Questions:

• How do we compare and analyze methods for solving real life problems? • How do you use graphical and numerical techniques to study patterns that occur in everyday

life? How do you develop a plan for collecting and analyzing data in order to make decisions?

TEKS/Essence Statements: • M.1(D): select a method to solve a problem, defend the method, and justify the

reasonableness of the results. Critical Skills/Postsecondary Goals: This section needs to be completed based on the students in your class. Instruction/Classroom Activities: Small Group Instruction: Clipping coupons is similar to clipping money, since any money saved, is extra money you will have. This is especially true with grocery shopping, as a dollar saved is a dollar earned. One place to find coupons is in your local papers advertisement section, in the grocery store ads. Look in your local paper for a week to see what days they print coupons. There are many different types of coupons. Clip some coupons and pass them around for the class to look at. What information is included on each coupon? (Coupon Amount, expiration date, etc). What different ways are there to save? (Money off, percentage off)

Teacher asks “How many of you have gone to the grocery store, asked for your favorite snack and Mom or Dad said that it cost too much? Maybe if it was a little cheaper or if you had your own money you could buy it, right? Today we will learn to figure up how much things cost and maybe use coupons to make them a little less expensive.” Each student is now provided with a) “shopping list”, b) a few coupons, c) two worksheets, d) a pencil, e) a calculator for checking work Teacher explains that adding and subtracting money is just adding and subtracting decimals with a cute sign in front. Teacher calls on a student to read one coupon. After the student reads the discount portion of the coupon, the teacher explains that when we use coupons they make the price of the item less; that means we subtract the coupon amount from the price of the items.

Student finds and announces the price listed on the list for the item that the coupon will be applied to. Teacher reminds the students of the number of items that must be purchased to use the coupon. Price of the item is written on the board, students are directed to copy the information onto their worksheets. If multiple items must be purchased the prices are written twice and summed the process is repeated if three items are required. Now the teacher reminds the students that we have a coupon and it will make the items cheaper. The amount of the discount is written on the board and subtracted from the sum of the items. This is the total cost of the items. Students are now directed to select three more items from their coupons and complete the procedure. Group work during selection of items is acceptable. Teacher will ask each student to provide one example. Any questions will be discussed and clarification provided. Teacher completes, on the board, a four-part computation using coupons and items as an example that the work is the same but one more price is added.

Application to Real Life: Students will learn ways to assist in the grocery shopping tasks of the household. They will also develop skills, which will enable them to compute the cost of snacks or other special items, which they wish to purchase from the grocer. This will be achieved through hands-on experience with the use of coupons. Adaptations: • The lesson can be adapted for by allowing the use of calculators if the idea that the prices are added and subtracted is the only concept that is being emphasized. • Prices and discounts could be pre-determined and filled-in on worksheets.

Stations/Centers: • Word Wall/Vocabulary Activities • Computer Research • Drawing/Writing Station

Individualized Communication Planning: This section needs to be completed based on the individualized communication needs of the students in your class.

Differentiated Tasks:

Resources/Materials: Worksheets, “shopping list” (teacher generated list of items to choose from with prices for each), coupons (only dollar amount discounts) for items in sales flyers, four calculators (for checking work and accommodation), extra pencils.http://www.heb.com/weekly-ads/ads-coupons.jsp?_DARGS=/common/sidebar-for-cold.jsp_A&_DAV=default&_dynSessConf=-7279910914943108164 ,http://teachers.net/lessons/posts/4007.html Assessment Strategies: This section needs to be completed based on the strategies appropriate for the students in your class. IEP Connections: This section needs to be completed based on the IEPs documented in the students’ ARDs in your class.

Level 3 Student will participate in coupon related activity.

Students will read and answer coupon questions

independently.

Level 2 Students answer questions

orally regarding coupon related problem-solving questions.

Students will use visuals/pictures to answer questions with assistance.

Level 1 Students will explore coupons.

Student will visually focus on problem coupon graphics

while listening to class discussion/text read aloud.
