Give students 1 minute of quiet think time, and then 1 minute to discuss the things they notice and wonder with their partner, followed by a whole-class discussion. openupresources. Definition A diagram is a visual representation that employs symbols and visuals to portray relationships, concepts, processes, or objects. x = -1 c. Like a seesaw, a scale, or a barbell. In this lesson plan, we will explore strategies for writing and solving equations with hanger diagrams that show addition and multiplication. Diagrams can be used in science, engineering, and mathematics. Will the hanger still be in balance, or will it tip to one side? Which side? Explain how you know. Students use the diagram to create an equation and balance it using the hanger for help, if needed. First hanger, unbalanced with left side lower, left side, green triangle, right side, blue square. Learning Targets: I can explain how a balanced hanger and an equation represent the same situation. 7. 7 = 3x f. Each piece is labeled with its weight. What do you notice? Introduce your students to solving two-step equations (some with variables on both sides) with these hanger equations. Use each of the 6 hanger diagrams containing squares and circles from the previous activity to write an equation that represents the weights on the hanger. Compare the solutions to the equations with the answers from the previous activity. com/ and https://openupresources. There are 3 unknown weights plus 6 units of weight on the left. Learning Targets I can explain how a balanced hanger and an equation represent the same situation. Which equation matches the hanger diagram? a. 3. *Make sure students have had some exposure to hanger models before completing this task. It includes one- and two-step equations. For the hanger to remain balanced, each side has to have the same weight. For example The balanced hanger shows 3 equal, unknown weights and 3 2-unit weights on the left and an 18-unit weight on the right.
