## Algebraic Thinking Level D

1. Mastery of Level C
2. Solving Expressions and Equations
Students will be able to:
• Use properties of operations to create equivalent expressions
• Solve multi-step problems in algebraic form in both contextualized
applications and abstract mathematics
Students will be able to:
• Use square roots and cube roots in equations
• Recognize and represent very large or very small quantities using
scientific notation
• Perform operations using scientific notation
4. Solving Linear Equations
Students will be able to:
• Understand the line of best fit
• Understand slope as a rate of change
• Understand a distance versus time graph with the slope representing
speed
• Compare rates with relationships represented in different ways (e.g., graph vs, chart)
• Solve systems of linear equations
5. Introductory Functions
Students will be able to:
• Define, evaluate, and compare functions
• Use functions to model relationships

Infinite Algebra I: One-step Equations

Algebraic Thinking C & D: In this activity, students will learn what the solution of a linear equation represents and how to solve a simple linear equation by applying an inverse operation. If the numbers (constants) in a linear equation are "nice numbers," students may be able to sole the equation by applying the inverse operation in their heads.
