Explore functions with non-constant rates of change. The first installment of a 12-part module teaches young mathematicians about the concept of a function. They investigate instances where functions do not have a constant rate of change.

Develop a more precise definition of similar. The lesson begins with an informal definition of similar figures and develops the need to be more precise. The class learns about dilations and uses that knowledge to arrive at a...

Prove the Angle Sum Theorem of a triangle using parallel line and transversal angle relationships. Pupils create a triangle from parallel lines and transversals. They find angle measures to show that the angles of a triangle must total...

Third graders participate in a game in order to review geometric concepts.

First graders explore the existence of patterns in everyday items. In this science and math integrated lesson plan, 1st graders match leaves with a name word card and organize them into four patterns. This lesson plan includes a reading...

Use the coordinate plane to show two figures are similar. The lesson incorporates congruence transformations and dilations to move a figure on to another figure. Pupils determine that if a similarity transformation exists...

What does similarity have to do with the Pythagorean Theorem? The activity steps through the proof of the Pythagorean Theorem by using similar triangles. Next, the teacher leads a discussion of the proof and follows it by an animated...

Is it a right triangle or not? Introduce scholars to the converse of the Pythagorean Theorem with a lesson that also provides a proof by contradiction of the converse. Pupils use the converse to determine whether triangles with given...

Examine the application of the Pythagorean Theorem in problem-solving questions. Pupils apply the theorem to find lengths when given different scenarios. They finish the 17th installment in an 18-part series by applying the theorem...

Students relate electrical power and how it works to math. For this geometry lesson, students analyze how a hydroelectric plant works and calculate the amount of electricity that is produced by a typical generator. This lesson uses...

Eighth graders investigate a lesson plan using the Order of Operations. The lesson plan has good instructions to carry out the lesson plan. The language is user-friendly for the average educator. They also use a Math writing journal to...

Fourth graders identify line symmetry. In this geometry lesson, 4th graders are given various pictures and identify if they are symmetrical. Students search through magazines for symmetrical pictures.

Students create a design of a circle. In this geometry lesson, students identify the measure of the diameter and radius of a circle. They graph and analyze their collected data and write equations based on direct variation.

Students find the different ratios of a triangle. In this geometry lesson, students use the Pythagorean Theorem to solve for missing sides and angles on a right triangle. They use a robot to create a right triangle.

Students identify points plotted on the coordinate plane. For this geometry lesson, students learn to read a map using concepts of a coordinate plane grid. They find the path given a map to tell them where to go.

Students calculate and find a certain location. In this geometry lesson, students examine a coordinate plane for pair of coordinates. They calculate the distance between point using the distance formula and estimation.

First graders identify geometric solids. In this shapes and solids beginning geometry lesson, 1st graders reach into a bag and identify the geometric solid they feel. Students describe shape attributes and match two dimensional shapes to...

Students research six different mathematicians using Internet resources. They examine the contributions of different cultures, women, and one that made a significant to geometry. They present their research to the class.

In this geometry worksheet, students study 4 pictures of shapes and using the word bank, label them. Students then draw the specified shapes in four more problems.

In this college level geometry worksheet, students convert between degrees and radians.  Students determine arc length and solve problems involving the area of a sector.  The four page worksheet contains seventy-four...

In this geometry worksheet, students solve problems by finding the area of a triangle. They are given the sides and asked to solve using the Pythagorean Theorem. There are 72 problems.

Students calculate the area of different polygons. In this geometry lesson, students draw shapes using different scale factors. They calculate and make sure there is enough room for te soccer arena through their calculations.

Students calculate the circumference of a circle. In this geometry lesson, students measure the diameter of a circle using micrometers or calipers. They investigate the relationship of the diameter to that of the value of Pi.

Using a 2002 California Gray David recall vote as an example, young statisticians  identify sources of bias in samples and find ways of reducing and eliminating sampling bias. They consider ways to select random samples from a...
