Groups write and evaluate expressions for various phone plans and scenarios to find which is the best deal. They then compare different approaches to writing expressions for the same scenario and discuss the concept of equivalent...

Students demonstrate different algebraic equations using Borenson's Hands-On Equation materials. They work in a cooperative group to solve algebraic equations.

In this algebra worksheet, students answer 37 multiple choice questions, each having to do with exponential operations. Twenty-five problems require students to multiply exponential terms. four problems involve dividing with exponents. 8...

Second graders are exposed to algebraic thinking by exploring the concept of a variable. They tell how many years have passed since they've seen a favorite teacher and then examine how they arrived at this number. They write equations.

Ninth graders practice pre-algebra and algebra skills by solving and entering the correct answers.

Fourth graders examine halves of a whole and discover through activities that they must be exactly equal in size. Working with Geoboards and Dot-Paper Squares, the class practices finding halves that are both congruent and incongruent.

In this algebra worksheet, students identify one to one functions by analyzing graphs of different equations. There are 6 different types of graphs to be analyzed.

Students graph inequalities on a number line. For this algebra lesson, students solve linear and compound inequalities and graph them on a number line. They write an inequality given the number line with the solution on it.

Students complete an open book Algebra II test. In groups, with one student designated as the leader, students complete a practice exam. They exchange answer sheets and grade their papers. Students take the papers home and use them to...

Fourth graders use inductive reasoning to find algebraic patterns in geometric figures. They use technology (i.e., calculators, computers) and manipulatives to discover number patterns involving geometric concepts. They solve concrete...
