Students explore secants and circles. In this geometry instructional activity, students identify the properties of two and three dimensional shapes. They create arguments to prove the theorems are true.

Students find the surface area of cones. In this geometry lesson, students calculate the dimensions of each three-dimensional shape and use the correct formula to solve the problem. They relate concepts of cones to the real world.

Students create a holiday ornament. In this Keith Haring art lesson plan, students use paper mache to make 3-dimensional ornaments that resemble his work. Students cut out felt shapes of babies, dogs and angels then sew them...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...

Students study writing. In this creative writing lesson, students write a story about having a robot and make a three-dimensional robot to accompany their writing.

Students find the perimeter and area of circles, triangles, and rectangles. In this perimeter and area lesson plan, the teacher gives students formulas for each shape and measurement and works through examples on the board. While no...

Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...

Students identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.

In this geometry worksheet, learners make a paper cube by following the directions given on the paper, They cut along the outside edge of the net, fold inward along the inside lines, and glue the flaps to hold the shape of the cube.

Students create three-dimensional cell models. They may choose to make either a plant or animal cell but must use a Ziploc bag as the cell membrane, slime for the cytoplasm, and strawberry baskets for the cell wall if making a plant...

A neat art project is on the horizon. Your class can experience impasto, or textured painting with this expressive art lesson. They design and then paint using the impasto technique. This is done by mixing toilet paper into the paint....

Identify the nets for prisms and other geometric shapes. Learners calculate the surface area of the rectangular prism then sketch the shapes of prisms and other polygons. Unfolded cereal boxes are used as a visual aid, great idea!

Students explore perimeter and area of regular and irregular polygons. They experiment with color squares and create different arrangements using the same number squares. Then they compare the area and perimeter measurements of each.

Geometry.... sweet! Using sugar cubes, learners build rectangular prisms of different sizes and shapes. They glue them together and assess volume. Then they color the outer sides to visualize and compute surface area. To make a visceral...

Third graders create 2D and 3D shapes using marshmallows and toothpicks. For this geometry lesson, 3rd graders create their shapes and document the number of faces, edges, corners, angles, and sides. They share one shape and its...

Students describe shapes to their classmates using specific properties and practice making triangles on geoboards. In this geoboards lesson plan, students use string on the geoboards.

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Students relate the colors in a garden to those in a rainbow by creating a multicolored three-dimensional garden portrait. They read, "Planting a Rainbow" by Lois Ehlert, then construct their garden with colored paper on white cardstock.

Learners explore points, lines and planes as it relates to geometry. In this geometry lesson plan, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.

Students explore basic shapes in Monet's paintings Wheatstacks, Snow Effect and Morning. They study about light and shadows through reading and experimenting with three-dimensional models and flashlights.

Students explore geometry by drawing various shapes in class. In this triangle characteristics lesson, students identify the attributes that classify a shape as a triangle and practice using their bodies to create triangles in class....

Students explore lines of symmetry. In this symmetry lesson, students divide and combine shapes along basic lines of symmetry. Students explore symmetry in real life objects.

Students study pyramids. In this prisms lesson plan, students explore the attributes of pyramids. Students will explore the lateral surface area of pyramids and be able to distinguish pyramids from other space shapes.
