Geometry is more than just vocabulary. Pupils learn the basic geometric definitions and how to identify and name points, lines, and planes. Though the first lesson is packed with related vocabulary, scholars experience four postulates...

Kindergartners listen to a story read by their teacher, then use magnetic shape pieces to construct simple designes. They "build" their own house using pre-cut paper shapes. This age-appropriate lesson would be an excellent choice for...

Geometry learners use hinged mirrors to discover that the regular polygons are composed of triangles tessellating around a center point. They sketch triangles on paper models of the regular polygons having 3 to 10 sides and compute the...

Fourth graders participate in a lesson that is about the finding of different fractional sizes with the help of pattern blocks. They define the vocabulary terms of numerator and denominator. The lesson also uses geometry and relates it...

Students raise their design awareness about construction considerations for large public facilities including safety, accessibility, funding, construction materials, and space, use geometry and other mathematical skills to calculate size...

Students gather information about the Melbourne Cup horse race in Australia. Then they study the geometry and physics behind the design of a racetrack. Students also work in small groups to problem solve and design their own board games...

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...

In this geometry instructional activity, students create circle, line and bar graphs using different comparisons of events. There are 24 questions with an answer key.

Connect literature (Jack the Builder) with mathematical concepts. In a series of computation, geometry and number sense activities, pupils count on to add, count back to subtract, build cylinders, cones, and rectangular prisms, and name...

Learners solve volume problems. In this geometry lesson, the class watches a video about clean water (link provided) and individuals compare the volume of different prisms, including an actual drinking glass. Extension activities include...

Students read The Greedy Triangle and discuss geometric solids. In this geometry lesson, students list the geo-solids in the world and create a graphic organizer to show where geo-solids exist.

In this geometry lesson, 10th graders break down a circle and identify the different parts. They discuss chords, diameter, radius, circumference, major and minor segment. There are 42 problems broken down into 5 different sections.

 In this geometry lesson, learners read The Greedy Triangle and use geoboards to construct geometric shapes. They identify the number of sides and angles each shape has.

Primary geometers create a picture using tangrams. In this geometry lesson, students read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their tangram pieces.

Use this geometry worksheet to have learners answer ten multiple choice questions based on their knowledge of transforming congruent figures.

Middle and high schoolers investigate all the different places in math that square root is present. In this geometry lesson, pupils discuss square roots as it relates to a right triangle and construction. They go over altitude, rise,...

Students investigate the area of squares and circles. In this geometry lesson, students calculate the area and probability of simple events. They work on a laptop using Safari.

Students investigate right angles. In this geometry lesson, students define the word "angle" and create a right angle finder from an index card. Students find right angles in their classroom. As an extension activity, students try to...

For this geometry lesson, math scholars brainstorm examples of rotations.  Using the SMARTboard, students observe a rotation. They create their own rotation using graph paper. Finally, pupils complete a worksheet and graph rotations.

Students conduct an experiment.  In this geometry lesson, students practice identifying, describing and comparing geometric solids.

In this geometry lesson plan on cylinders, geometers explore how to find the smallest surface area for a given volume.  They use their knowledge to relate it to the real world by making a model of a livestock tank.

This engaging presentation would be helpful for your young learners of geometry. Pupils are given clues as to what a shape may be, then they have to use those clues to guess what shape is being described. Shapes used are the circle,...

Geometry novices will enjoy this approach to finding area, as they aren't required to include units or a formula. The main objective here is to segment a rectangle into columns and rows to create squares, which then are used to find the...

Youngsters add some shapes to this castle drawing before analyzing its geometry. They count the circles, triangles, rectangles, and squares. The objectives here include drawing, recognizing, and counting shapes as well as writing numbers...
