Day 42: Generate Equivalent Expressions / Simplify Algebraic Expressions

Today, during Math 6(1°), students worked with Lesson 3.6: Generate Equivalent Expressions. To begin, Mr. Giomini introduced various properties of operations for the students to record in their notebooks. Modeling and knowing these provided the groundwork for the activity.

Students were then given an algebraic expression and asked to use one of the properties of operations to create an equivalent expression. To justify their equivalent expression, students needed to substitute multiply values to ensure that both provided the same value.

In Math 6(3/7°) and Math 6+, Mr. Giomini introduced Lesson 3.7: Simplify Algebraic Expressions. The focus of this lesson was to combine like terms in an attempt to simplify algebraic expressions. Students needed to identify like terms by using variables and coefficients. 

 Lesson Objectives: The student will be able to...

• identify parts of an expression using mathematical terms (sum, term, factor, quotient, product, coefficient)
• evaluate expressions at specific values of their variables.
• perform arithmetic operations including those involving whole-number exponents.
• apply the properties of operations to generate equivalent expressions.
• identify when two expressions are equivalent.
