Topic: Algebra: Equivalent Expressions Apply the properties of operations to generate equivalent expressions. Students will use the distributive property to write equivalent expressions. They will also have to find common factors of terms in an expression. Example(s): Apply the distributive property to generate the equivalent expression of 5(m + 3). Solution: 5m + 15 Write the equivalent expression for 24a - 12. Solution: 12(2a - 1) Students interpret y as referring to one y. Thus, they can reason that one y plus one y plus one y must be 3y. They also use the distributive property, the multiplicative identity property of 1, and the commutative property for multiplication to prove that y + y + y = 3y: y + y + y = y x 1 + y x 1 + y x 1 = y x (1 + 1 + 1) = y x 3 = 3y Glencoe 5-2A Algebra: Properties (pages 289-293) 5-2-B Explore The Distributive Property (pages 294-295) 5-2C The Distributive Property (pages Task: Conjectures About Properties Task (Math Task Folder Holt 1 – 4 Properties and Mental Math A-1 Model Arithmetic Properties Task: Conjectures About Properties Task (Math Task Folder Language Objective(s): Students will describe how to use the properties of operations to generate equivalent expressions.
