Day 39: Math 6 - Equivalent Expressions / Math 6+ - Compound Inequalities

Math 6 students worked with Lesson 3.6: Generate Equivalent Expressions. In this lesson, students learned about the three properties of numbers:

Math 6+ students worked with compound inequalities. 

Standard(s) addressed in today's lessons:

Math 6: 

• Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3 (2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.

Math 6+:

• Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem. For example: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. Write an inequality for the number of sales you need to make, and describe the solutions.
