High School Mathematics Algebra I Part I Unit 2Subject: MathematicsCourse: Algebra I Part I
Timeline: 9-14 Days
Unit 2 Title: Linear Equations and InequalitiesUnit Overview:This unit will require students to evaluate patterns to write equations, and write and solve one-step and multi-step equations and inequalities given a problem context or a model. Inequalities will be graphed on a number line.
This unit will also require students to determine if an equation is always, sometimes, or never true. The concept of solving multi-step equations is expanded to include literal equations and formulas, many of which are based on science topics. Students are expected to compare and contrast solution methods for a variety of different problem types and communicate their mathematical thinking verbally and in writing.Unit Objectives:By the end of Unit 2, all students will be able to:
- model linear equations using multiple representations and patterns;
- write and solve one-step equations given a problem context, justifying steps using properties;
- classify equations based on whether they are always, sometimes, or never true;
- write and solve multi-step equations and inequalities given a problem context, justifying steps using properties;
- manipulate and solve literal equations and formulas.
