Students define and identify transformation and rotation. In this geometry lesson, students define rotations as congruence or isometry. They find the coordinates of an image and pre-image.

In this central and inscribed angles worksheet, 10th graders identify and solve 20 different problems that include determining inscribed angles and intercepted arcs. First, they determine the measure of point P if the given angles are...

In this angles of polygons instructional activity, 10th graders solve and complete 18 different problems that include determining various interior and exterior angles. First, they determine the measure of various angles described in the...

In this geometry worksheet, 10th graders are given real world problems dealing with are and perimeter. They solve using the formulas for area and perimeter. There are 3 problems.

Students study geometric terms related to circles and solve the problem posed in the book.

Students identify tangents, chords and secants. In this geometry instructional activity, students graph circles and identify angles created by secant lines, tangent lines and chords.

In this geometry activity, 10th graders determine area and perimeter of rectangles, given the width and the length. The one page interactive activity contains ten questions. Answers and hints are included. 

How can you formally assess understanding of circle concepts? Pupils take a mid-module assessment containing five questions, each with multiple parts.

Help your learners examine triangles. Pupils explore the different sizes and measurements of triangles. They discover triangles can be isosceles or scalene, and examine the attributes of triangles. Here is the website where you can...

Use geometry to improve your pool game! Learners analyze the front half of a pool shot to determine its resulting path. By measuring the angle of incidence, they are able to predict the path of the ball. 

Apply geometry to find the distance as the crow flies. An engaging lesson compares the distance a car must drive to the straight line distance between two locations. Scholars must manipulate a simulation, note the change in distances,...

When going for distance, does it make a difference at what angle you launch the rocket? Teams of three launch foam rockets, varying the launch angle and determining how far they flew. After conducting the series of flights three times,...

It's time for scholars to show what they know about coordinate planes with a collection of three assessments. The exams' objectives include plotting points on a single grid, measuring using the distance formula, and identifying...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Time to learn about sundials. Scholars see how to build sundials after learning about Earth's rotation and its relation to time. The unit describes several different types of possible sundials, so choose the one that fits your needs — or...

Off they go — launching rockets is fun. The lesson plan contains templates to build paper rockets that can be launched from a PVC pipe launcher. Individuals or groups build the rockets and determine the shapes for their fins. Included...

In a nose-cone to nose-cone competition, which rocket will prevail? Teams form rocket companies to design and build a rocket while competing against other teams in an economic challenge. The team that comes up with the best benefit/cost...

Your geometry learners determine the measure of remaining angles in sets of three given that the other two are complementary or supplementary. From a diagram, they identify which angles are supplementary, complementary or congruent from...

An interactive challenges mathematicians to round large numbers with help from a large scale that measures the weight of a blue whale. The practie's five questions include multiple-choice, fill-in-the-blank, true or false, and an open...

A five-question interactive test scholars' knowledge of adding and subtracting decimals. A tool aids in problem-solving with movable parts that reveal addends and sums. Question types include one discussion, fill and in the blank, and...

Students investigate measurement.  In this fifth/sixth grade mathematics lesson, students explore the relationship between inches and centimeters.  Students measure their height in inches or centimeters and convert the...

In this construction worksheet, students utilize a compass and a ruler to reconstruct a line segment and to combine two line segments together in 2 questions.

In this geometry worksheet, 10th graders find the base, height, or area of a triangle. The one page interactive worksheet contains ten questions. Answers and hints are included. 

Students explore tessellations. In this shapes and geometry activity, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.
