1. Bring a pound or two of sunflower seeds in their shells to class, along with five or six small paper or Styrofoam cups and a bowl large enough to hold the seeds. Make several copies of the situation cards printed on the following...

In this algebra activity, students solve equations using addition, subtraction, multiplication and division. They solve word problems using equations. There are 5 questions with an answer key.

In this algebra worksheet, students solve problems using the GCF. They factor out the common variables and simplify the equations. There are 8 questions with an answer key.

Cut-and-paste a great activity into your lesson plans. Scholars analyze real-world problems involving proportions. To change things up a bit they cut-and-paste quantities to create a proportion on their way to solving the problems.

Buying a new sofa? Learn how to use the Pythagorean Theorem, as well as algebra and graphing techniques, to determine whether the sofa will fit around a corner (which I'm sure you'll agree is a very important consideration!).

Does temperature affect the air pressure of a football? Young mathematicians look at the readings from a pressure gauge and determine if the balls are within regulation or are under inflated.

Horses need exercise, too. Scholars create linear equations to model the perimeter of exercise fields for horses. They finish by solving their equations for the length and width of the fields.

Relate factors to zeros and x-intercepts. Scholars first graph quadratics in both standard and factored forms to see that they are the same. They go on to use the graphs to see the relationship between factors and x-intercepts.

Investigate field properties of real numbers. Scholars use a table for a given operation to determine the identity element. They use the same table to find a missing value in an equation.

Students participate in a lesson that covers the concepts of solving equations and inequalities. To master the concept they must demonstrate visually and verbally how both sides of an equation must be balanced. They construct a balanced...

In this math activity, students solve the expressions with using the values of the variables to find the solutions. They also solve the set of proportions.

In this Algebra I worksheet, 9th graders represent verbal expression algebraically and evaluate the expressions for the given replacement values of the variables. The three page worksheet contains the instructions for the card game and...

For this writing equations for comparison word problems worksheet, students use a as the variable in equations, compare numbers, and solve. Students solve six problems.

In this angle measures worksheet, 10th graders solve and complete 6 different types of problems. First, they find the coordinates of each angle given. Then, students determine if the angles are complementary or supplementary. They also...

In this operations and functions worksheet, students add, subtract, multiply, and divide functions.  This one-page worksheet contains 18 multi-step problems. 

Students read three case studies to focus on how the United States dealt with foreign policy issues. In groups, they read about the decision to drop the atomic bomb, the commitment of troops to Vietnam and wwhether to send troops to...

Students study the types and parts of seeds and how they have evolved.  In this germination lesson students complete experiments that show the effects of variables role in seed germination. 

Students solve systems of 2-by-2 linear equations using tables, graphs and substitution. In small groups, classmates work together to discover strategies for solving equations. They use a calculator to graphically represent their answers.

Young scholars investigate Income and gender preference. In this statistic lesson, students collect data of Income to see if one gender makes more than the other. Young scholars examine the data and draw...

Students watch the teacher demonstrate on an overhead projector how to graph various equations before the students try them on their own. They start with pencil and paper; once they grasp the concept they move on to punching in the...

Students experiment with graphing. In this graphing introduction lesson, students complete four activities: 1) a bar graph based on class birthdays 2) an estimation graph of the raisins in raisin bread 3) another estimation example with...

Use this video to show your learners an example of how to translate word phrases into an equation to solve a real-world problem. The presenter begins with a review of how to use cross products to solve a proportion, including how to do...

What would your dream house look like? A cottage? A medieval castle? High schoolers enrolled in Algebra design the perfect house while using slopes to write equations for various aspects of the project.
