Lesson Plan By: Marc Walter Length: 30 minutes Lesson: Trail Mix Age or Grade Intended: 3 rd Academic Standard(s): Standard 5: Measurement Students choose and use appropriate units and measurement tools for length, capacity, weight, temperature, time, and money. 3.5.10 Find the value of any collection of coins and bills. Write amounts less than a dollar using the ¢ symbol and write larger amounts in decimal notation using the $ symbol. Performance Objectives: Given the price of different ingredients, the student will make a trail mix of five different ingredients without exceeding the budget with 100% accuracy. Assessment: The student will need to buy five different ingredients from the teacher without exceeding his/ her budget of five dollars. Materials Needed:
· Pretzels, M&Ms, Skittles, Twizzlers, Popcorn, Jelly Beans, Peanuts, Candy Corn, Gummi Bears, and Cracker Jacks
· One zip­lock bag per student
· Play money (five and one dollar bills, quarters, dimes, and nickels) Advanced Preparation by Teacher: Students must know the value of a dollar and coins. The teacher must put a price amount on each of the goods that the students can purchase. (Pretzels= $1.25, M&Ms= $1.75, Skittles= $2.00, Popcorn= $.75, Jelly Beans= $1.25, Peanuts= $.90, Candy Corn= $1.15, Gummi Bears= $1.35, and Cracker Jacks=$1.50) Procedure Intro: We are going to be making our very own trail mix and you get to choose what goes into your zip­lock bag. Can anyone remember what a good is? (Bloom, Knowledge) Yes, a good is something that satisfies a person’s wants. Step­by­Step Plan: Ok, I have ten different goods written on the board. Each other these goods have a price amount that you must pay in order to buy them for you trail mix. For example: if the pretzels cost $1.25, the M&Ms cost $1.75, and the peanuts cost $1.00, how much of these items can I purchase for my trail mix if I only have five dollars? (Bloom, Application) Good job, there isn’t just one correct answer. Now, I need you to take out a piece of paper and your pencil. I am going to write the goods that you can purchase for your trail mix on the board and write the amount that each one cost. When I finish doing this, you need to think of the different goods you want to purchase and total up the amount. (Gardner, Logical/Mathematical) However, you will only have five dollars to use when buying these goods. After you have made a list of the different items you want to purchase, you must make sure you haven’t spent more money than you
have. Try to spend as much money as possible without going over five dollars, because this way you get to have more goods in your bag! After the students have finished creating their lists, give each student a fake five dollar bill and a zip­lock bag. Explain to the students that you are a greedy business man and might try to give back the wrong amount of change in your favor, so they must count back the change that I give to them. Tell the students that once they buy a good to put it in the zip­lock bag until we are finished purchasing goods, and then they can eat whatever they have purchased. Now that the students are ready to purchase the goods, call one student to the board to purchase their first item. Continue this until each student has purchased one good, then begin with their second purchase and so on until each student can’t purchase anymore items. When the students are no longer able to purchase anymore goods tell them that they can now begin to eat the goods that they have purchased or they can place their zip­ lock bags in their book bags to take home for later. Closure: Great job today class! Can anyone explain to me what the items on the board are called? Yes, they are goods, and today everyone of you were consumers because you purchased goods. Tomorrow we are going to be discussing what trade is and what you can do when you trade. We will learn that you can trade goods for services. Adaptations: Give the student a calculator. Enrichments: Give the student the wrong amount of change back to see if they can calculate the correct amount in which they should have received.
