Domain: 7th Grade Mathematical Practice(s): Level of Thinking: Expressions & 1. Make sense of problems and persevere in solving them. Applying Equations 2 Reason abstractly and quantitatively. 6 Attend to precision. 7 Look for and make use of structure. 8 Look for and express regularity in repeated reasoning. Grade Specific Standard: 7.EE. 2. Use properties of operations to generate equivalent expressions. Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. For example, a + 0.05a = 1.05a means that “increase by 5%” is the same as “multiply by 1.05.”
Information Technology Standard: 7.TT.1.1 Use appropriate technology tools and other resources to access information. Clarifying Objectives: Generate more than 1 equivalent expression from a real-world problem.
Task Analysis Vocabulary Review Recall mathematical properties of operations Integers as they apply to rational numbers (integers) Expressions Equivalent Quantity Explain that expressions in different forms can Commutative, Associative, Distributive, be equivalent, and rewrite an expression to Substitution properties represent a quantity in a different way. Coefficient Variable Generate equivalent forms of the same expression given a word problem (a 20% discount = 80% of the cost). Instruct Additive Inverse Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. For example, a + 0.05a = 1.05a means that “increase by 5%” is the same as “multiply by 1.05.
