Day 40: Math 6 - Combine Like Terms / Math 6+ - Compound Inequalities

Math 6 students worked with the final lesson of Topic Three - Lesson 3.7: Simplify Algebraic Expressions. In this lesson, students worked to combine like terms when analyzing algebraic expressions to help simplify the number of terms an expression possesses. Refer to the video below to help clarify any misconceptions.

Students in Math 6+ continued their work with compound inequalities. 

Standard(s) addressed in today's lessons:

Math 6: 

• Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.
• 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.
