Curated OER
Exploring Expressions
Examine parts of an expression in this algebra lesson. Ninth graders identify the properties of the coefficient and their behavior to the graph. They graph the equation on a TI to see their results.
Curated OER
From Expressions to Equations
Learners differentiate between expression and equation by evaluating integers and observing the difference. They use the TI to see the steps to solve problems.
Curated OER
SHHH It's a Secret
Students rewrite word problems using expressions and equations. In this algebra lesson, students use the correct variable to solve and write equations. They use the TI to graph their solution.
Curated OER
Solving Algebraic Expressions
Students simplify equations and expressions. For this algebra lesson, students add, subtract, multiply and divide as they solve expressions. They relate factoring to solving polynomials.
