Overview
Build algebraic thinking from the ground up. Learn to read expressions, write equations and inequalities, and model everyday situations like budgets, bills, and schedules with confidence.
Syllabus
- Course 1: Make Sense of Expressions and Inequalities
- Course 2: Model Situations with Expressions
- Course 3: Set Up Equations and Inequalities
- Course 4: Understand and Use Math Models in Real Life
Courses
-
You'll build the vocabulary and reading habits that algebraic thinking rests on. You'll learn to spot what varies in a situation, assign variables that actually mean something, read an expression part by part, and tell expressions, equations, and inequalities apart before writing any model yourself.
-
You’ll turn everyday situations—like shopping, work, and travel—into expressions that represent real relationships. You’ll build expressions step by step, use grouping when needed, and recognize when different expressions represent the same situation.
-
You’ll translate real-world constraints into math. You’ll represent exact targets with equations, interpret everyday language into inequalities, and model limits and ranges from budgets, rules, and schedules.
-
You’ll use expressions, equations, and inequalities to understand real situations. By plugging in values, estimating results, and interpreting constraints, you’ll learn how to check whether a model makes sense and explain what it means in everyday terms.
