The fifth installment in the series of 28 lessons helps math scholars explore the result of adding opposite numbers and multiplying reciprocals. Through this exploration, they develop a working definition of identity and inverse properties.

You know how to factor expressions; now it's time to go the opposite way. Scholars learn to write algebraic expressions in expanded form using the distributive property. A problem set helps them practice the skill.

A thoroughly-written lesson plan and a plethora of worksheets about integers comprise this resource. Neophyte number crunchers learn to recognize integers, add and subtract them, and apply the concepts to the designing of a personal...

It doesn't get simpler than this. Scholars first learn to simplify radicals by determining the prime factors of the radicand. The lesson progresses to simplifying radicals involving algebraic expressions in the radicand.

Scholars first learn to graph square root and cube root functions by creating a table of values. They then learn how to graph functions from transformation of the graphs of the parent square root and cube root functions.

Students find the area of polygons.  In this area of polygons lesson, students find the area of parallelograms, rectangles, squares, and other polygons.  They identify each given figure and determine the appropriate formula...

Ninth graders discuss the real number system and its' properties. In this algebra lesson, 9th graders discuss rational, irrational, closure, real numbers and the distributive property of algebra. They solve problems using these...

Students investigate and solve linear equations using slopes. In this algebra lesson, students graph lines using the slope and y intercept. They also find the slope by rewriting their equation in to slope-intercept form from standard form.

Students discover the game of chess. In this critical thinking lesson plan, students learn the rules for each chess piece and the game as a whole. Students use critical thinking, problem solving, logic, and reasoning skills to improve...

Can two lines intersect at more than one point? Using yarn, create two lines on the floor of the classroom to find out. Cooperative groups work through the process of solving systems of equations using task cards and three different...

Students graph the absolute value of compound inequalities. Through a demonstration, students discover the meaning of absolute value. They take notes, rewrite opposites, and solve for each variable. Students complete a worksheet and...

Eighth graders graph solutions to problems on a number line. After discussing algebraic expressions, 8th graders discuss how to solve them using an inequality. They observe examples and then work problems at their desks and on the...

Students solve problems using the opposite, reciprocal and powers. In this algebra lesson, students solve problems with inequalities and absolute values. They show understanding of the basic content of math in this lesson.

Students review solving absolute value equations. They watch as the teacher demonstrates solving a system of linear equations by addition. Students practice working problems by multiplying to obtain opposite cooefficients, and then...

Students compare and order integers on an umber line. In this algebra lesson, students differentiate between positive and negative numbers. They plot point in the correct order on a number line.

Middle schoolers investigate properties of additive inverses.  In this properties of additive inverses lesson, students discuss the what it means for two numbers to be opposites.  Middle schoolers discuss representing opposite...

Fifth graders solve equations. In this algebraic equations lesson plan, 5th graders use the inverse operation to solve an equation. The teacher reminds students to perform the operation on both sides of the equation. This lesson plan...

Prealgebrarians use colored chips, stickers, and pencils to explore the world of integers. They discover absolute value, compare positive and negative integers, and apply operations to them. A detailed procedure for the three-part...

Students analyze the concept of profit and loss, the components of a simple profit and loss statement and the importance of a profit and loss statement. They calculate profits using gross income, total expenses and cost of goods sold....

Bring balance to your lesson plans with an activity that asks individuals to solve one-step linear equations with inverse operations. Balance scales help learners understand the concept of isolating the variable.

Learners calculate the maxima and minima of quadratic equations. In this calculus lesson, students apply the derivatives by finding the maxima and minima using real life application. They solve optimization using the derivative. 

Young scholars explore the concept of adding integers.  In this adding integers lesson, students simulate the battle of the 300 spartans at Thermopylae.  Young scholars use colored game pieces to represent positive and negative...

Students visit a web page that gives a brief introduction to two color models and experiment with mixing different color intensities to create different colors. They visit links that give more detailed information on color.

Learners explore numbers patterns and write equations to describe the pattern. They apply the equations to further the patterns.
