Scholars learn how using algebra tiles to add and subtract polynomials can model how to combine polynomials. They use their newfound knowledge to complete a worksheet of problems.

Don't cover up this resource — use it out in the open! Pupils learn how to cover up various parts of a linear equation in order to help solve the equation. A worksheet of problems provides practice with this skill.

Apply systems of inequalities to a real-world problem. Here, scholars learn to graph solutions to systems of linear inequalities. To finish the lesson, they solve a problem involving burgers and cheeseburgers using a system of inequalities.

Develop a strategy for finding the area and perimeter of irregular figures. Building on an understanding of finding area and perimeter of rectangles and triangles, learners apply the same concepts to composite figures. After...

Investigate the relationship between independent and dependent variables. Individuals begin by identifying independent and dependent variables from different problem situations. Then, using specific guidelines, they create posters...

If only you had a Sorting Hat to sort out quadrilaterals. Learners sort cutouts of quadrilaterals based on their properties and attributes. A flowchart helps them organize the results of the activity.

Future mathematicians learn about arithmetic and geometric sequences, as well as common ratios and differences as they complete a worksheet matching sequences with the algebraic expressions that represent them.

Don't forget to tip your server. Future consumers learn how to calculate sales taxes and tips. Pairs use actual restaurant menus to create an order and determine the total bill, including taxes and tips.

Surface area or volume? Pupils first review the difference between surface area and volume. They then use a two-dimensional net that helps them develop formulas for the surface area and volume of cylinders.

Fill the minds of your young mathematicians. A hands-on activity has learners fill in a rectangular prism with unit cubes to determine its volume. the exercise provides a great hands-on way for learners to connect the activity...

How similar do figures have to be to be similar figures? Individuals learn to identify similar figures by verifying that angles are congruent and sides are proportional. Additionally, they match the corresponding parts of similar figures.

Young mathematicians extend their knowledge of rational numbers on a number line to graph inequalities by first using number cards to compare rational numbers. They finish by using similar reasoning to graph inequalities on a number line.

Scientific models help explain ideas and concepts to non-experts. The online activity covers conceptual, mathematical, and physical models. Through four multiple-choice questions and three discussion questions, scholars gain a deeper...

Students participate in an on-line virtual field trip to the state of Alaska. In this U.S. Geography lesson, students research several Internet sites dealing with travel to Alaska and activities to participate in. Students create story...

Students explore the concept of trig identities. In this trig identity lesson, students use Mathematica to graph trig identities. Students see the trig identities graphically and enforce the notion that two trig functions can be equivalent.

First graders demonstrate how to use cookies to create different fractions. In this math lesson, 1st graders build their knowledge based on what they hear after the teacher reads Eating Fractions by Bruce McMillan by cutting a...

Fifth graders solve word problems. In this math instructional activity, 5th graders read the word problem and determine what is being asked. Students solve the problem and explain how they reached their solution.

Students design and build their own solar cooker. For this math lesson, students determine the relationship between the angles of the sun, reflection and cooking time of the solar cooker. They test their project, collect data and...

Second graders complete math activities with donated seasonal treats. They estimate, count, sort, name and graph bags of treats. They can eat treats when finished.

Seventh graders explore surface area. They study the difference between two and three-dimensional objects. The teacher leads a discussion about finding the surface area of different size cubes. In pairs, 7th graders use graph paper to...

Students draw and calculate altitudes. They draw the altitude of acute, right and obtuse triangles and calculate the altitude of a triangle using the Pythagorean theorem.

Second graders read the rules of how they can balance the scale by placing beans in the square, circle, and the triangle. Next, they balance 12 beans using the scale and then try to balance it with 15 beans, and then 18 beans. They then...

Students explore the mathematics behind opinion polls, as well as provides a framework for interpreting trends in opinion poll graphics.

Pupils use Gallop Poll results to explore causes and effects of the concerns of Americans in the past. They administer a similar poll and consider what Americans in their community view as the most pressing problems in the United States...
