7th Grade Advanced Math Unit 12

Big Idea:

• Solving equations involving distributive property, graphing and functions
• Functions, graphing, equations and distributive properties, financial literacy
• Equations and transformations (mainly dilation)

Student Expectations:

Priority TEKS

8.10(B) [Supporting] Differentiate between transformations that preserve congruence and those that do not.

8.10(D) [Supporting] Model the effect on linear and area measurements of dilated two-dimensional shapes.

Focus TEKS

8.4B[Supporting] Graph proportional relationships, interpreting the unit rate as the slope of the line that models the relationship.

8.5B[Supporting] Represent linear non-proportional situations with tables, graphs, and equations in the form of y=mx+b where b is not = to 0.

8.8A[Supporting]Write one-variable equations or inequalities with variables on both sides that represent problems using rational number coefficients and constants.

8.8B (S) Write a corresponding real-world problem when given a one-variable equation or inequality with variable on both sides of the equal sign using rational number coefficient and constants.

8.8C(R) - Model and solve one-variable equations with variables on both sides of the equal sign that represent mathematical and real-world problems using rational number coefficients and constants.

8.12F(S) - Analyze situations to determine if they represent financially responsible decisions and identify the benefits of financial responsibility and the costs of financial irresponsibility.

8.8C(R)- Model and solve one-variable equations with variables on both sides of the equal sign that represent mathematical and real-world problems using rational number coefficients and constants

Learning Targets:

• Review for Algebra - functions, distributive property, graphing, and equations
• Look at accounting (how to write checks and a check register)
• Factoring
• Prime numbers
• Main emphasis on solving equations with multiple terms and variables on both sides
• Factoring
• Greatest common factor
• Writing and solving equations
• Dilation from 22x29 cm to 22x28 inches projects

Essential Questions:

• Given this ”problem” - do you see how we used the above concepts at a new level of difficulty?
• What are the parts of an equations? Distribution?
