The topic of trigonometric ratios is often covered with loads of rote memorization baked into the activity. This activity set, however, leans more on using similar triangles and discovery learning to help young geometers develop a deeper...

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. 

Build a solid foundation on which to develop future concepts. Through a guided exploration, learners compare and contrast the characteristics of points, lines, planes, rays, and segments. They measure lengths and practice notation for...

What do skateboarding and baked goods have in common with math? You can use them to connect half-pipe ramps and cakes to arcs and sectors. Pupils compare the lengths of three different ramp options of a skate park. They calculate the...

Learners estimate and measure triangles. For this geometry lesson, students identify the relationship between three sides and a triangle. They use the inequality theorem to decide if a triangle will be formed or not.

Students explore fractal geometry. They do online explorations of fractals to discover applications of fractal geometry for a report.

Students are introduced to the basics of Geometry. Using cutout shapes, they identify whether they are polygons by using the properties of polygons. They practice drawing shapes they are going to be using on an everyday basis and...

Define and review math vocabulary. Use the CEENBoT to draw pictures that represent each vocabulary word. Pupils work in groups to play math pictionary.

Students read the book The Math Curse by Jon Scieszka and study geometry. In this geometry lesson, students identify geometric shapes and their properties. Students create a geo-critter.

In this three dimensional figures review activity, students use their math skills to identify the 10 three dimensional figures pictured on the sheet.

Fourth graders recognize and classify geometric figures. In this geometry lesson, 4th graders read the books Shape Up and The Greedy Triangle and prepare a short report on the shapes mentioned in the text. Students compare the...

Students explore how geometry is used on the composition of artworks by artists from different cultures. This lesson is equally suited for a Math or Art classroom at the late-elementary or early-middle school level.

Students investigate the ties that architecture and math have in common. They focus on works of architecture in the world that is considered of great significance. Students use the internet to find building images from around the world....

Students identify the pattern in a problem. In this geometry lesson plan, students make predictions, collect and analyze data. They apply the idea of scales and measurements to the real world.

In this geometry worksheet, 10th graders determine if a polygon is convex or concave and apply the polygon Angle sum theorem and the polygon exterior angle sum theorem to determine the measures of interior and exterior angles of a...

Students study the basic principles of right triangle geometry needed to solve for unknown values of a right triangle. They apply and master the principles of right triangle geometry by solving problems.

Fourth graders combine geometry and language arts skills while examining quilt-making. After identifying the geometric shapes contained in quilts, they write stories to encompass the quilt border. Students conclude by creating and...

Students have fun with math. In this math skills lesson, students collaborate to solve the problems presented in this interactive lesson. The problems pertain to geometry, measurement, probability, number sense, and algebra.

Fifth graders participate in a review game of geometry topics. In this geometry lesson plan, 5th graders use the "Eggspert" interactive classroom game system to review the geometry skills taught that week. Students work in teams to...

Students define important vocabulary words using a dictionary. For this geometry lesson, students identify and use properties of triangles to solve problems. They identify the median. altitude and angles as well as properties of...

In this geometry activity #13 activity, 10th graders work in groups to solve 6 geometry problems, involving measurement of angles.

In this online math worksheet, students complete a 20 problem multiple choice online interactive worksheet with mixed skills including geometry, rounding, and three digit multiplication.

Students identify and name basic shapes and points. In this elementary geometry lesson plan, students use printable cut outs to name circles, triangles, and squares before playing a game with them. They play a game of "Pin the Tail on...

Students recognize and measure geometric shapes within abstract art. They examine quilts for shapes and they each make their own quilt from squares using geometry and measurement.
