Does the number of calories you eat affect the total time you sleep? Young mathematicians tackle this question by collecting their own data and making comparisons between others in the class through building scatter plots and regression...

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

While there are many types of equations to solve, the main focus here is on quadratics. Starting with a quick review of the different methods, learners are guided through the solving process and are challenged to solve higher level...

This is a nice worksheet on solving one variable and compound inequalities. Learners solve inequalities and graph the solution on a number line.  The two page worksheet contains explanation and sixteen practice problems. 

Start with the definition of a determinant and how to evaluate a 2x2 determinant. Apply this skill to solve systems of two equations with two unknowns by using Cramer's rule. These four basic problems would be good for a quick review or...

In this Algebra II learning exercise, 11th graders determine the solution to a system of one linear and one quadratic equation.  The two page learning exercise contains a combination of nine multiple choice and free response...

Graph equations of lines using the slope-intercept method or by plotting both x and y intercepts. Determine if two lines are parallel or perpendicular by comparing their slopes. This handout includes step-by-step directions and four...

How can you make solving radical equations more engaging? Provide your math class with a hands-on activity that focuses on solving radical equations with flash cards. A warm-up and exit ticket flank direct instruction of the steps...

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.

Is there another way to view whether the data is linear or not? Class members work alone and in pairs to create scatter plots in order to determine whether there is a linear pattern or not. The exit ticket provides a quick way to...

Here is a fun project. Sammy observes a chipmunk and a squirrel to see how many holes each needs in order to stash the same number of acorns.  Scholars could find the answer algebraically or create a table to analyze the...

This fourth of twelve units in a series continues the investigation of functions through equations and inequalities. However, the modular nature of the lessons in the section make this an excellent resource for any curriculum...

Can you justify that mathematically?  Help learners see the process of solving as using mathematical properties rather than a set of steps to memorize in the fourth module of a nine-part Algebra I series. The module contains six...

This activity presents a game played by two learners whose solution is an exercise in creating and analyzing with algebraic inequalities. 

It seems the post office has run out of stamps! Learners build all the values of postage available if the post office only sells five- and seven-cent stamps. The task provides an opportunity to create an expression in two variables and...

In this two-step linear equations worksheet, 7th graders solve 15 various problems that include linear equations with more than one-step. First, they need to get the variable, x, alone by subtracting/adding the whole number on the same...

In this algebraic equations instructional activity, student solve thirty word problems from single variable algebraic equations.  Two of the thirty problems are solved as examples.

In this equations review activity, students solve algebraic equations with one variable.  They use inverse operations to solve for the unknown.  Students translate word sentences to number sentences and then solve.  This...

In this quadratic equation worksheet, students read short statements and write a quadratic equation to represent the statement. Afterwards, they solve the quadratic equation using factorization. Twelve problems are provided on this...

In this combining like terms instructional activity, students solve for "x" by combining like terms in each math equation. Each problem contains two positive variable terms. Students add the coefficients to combine them. They subtract...

OK, so maybe graphing linear equations can be fun. This activity includes a set of linear equation cards to be cut and place face up on a table. Learners pick a card and match it to the correct graph card. This is a really fun way to...

Graph polynomials and identify the end behavior of each polynomial function. The class differentiates between linear, quadratic, and other polynomial equations.

In this systems of equations instructional activity, students solve 20 problems. The first 6 problems have one equation in the y-intercept form. The following 10 problems have one variable that has a coefficient of +1. The final four...

Model the flight of a ball. Small groups collect time data for how long it takes to toss a ball between two people. The teacher leads a discussion about projectile motion to get the class thinking about how to calculate the equation of...
