​Bellwork

​Objective: The student will solve two-step equations.

​

Math Standard: MA.7.AR.2.2 Write and solve two-step equations in one variable within a mathematical or real-world context, where all terms are rational numbers. Clarification 1: Instruction focuses the application of the properties of equality. Refer to Properties of Operations, Equality and Inequality (Appendix D). Clarification 2: Instruction includes equations in the forms 𝑝𝑥 ± 𝑞 = 𝑟 and 𝑝(𝑥 ± 𝑞) = 𝑟, where 𝑝, 𝑞 and 𝑟 are specific rational numbers. Clarification 3: Problems include linear equations where the variable may be on either side of the equal sign.
