Students identify and sketch the nets for sphere. In this geometry lesson, students differentiate between two and three dimensional shapes. They find the surface area of each sphere.

Students examine how feelings of caring and working together can be expressed in works of art, and define the terms two-dimensional and three-dimensional. They design and create celebratory hats using three-dimensional paper techniques.

Learners recognize, describe, and perform transformations (rotation/turn, reflection/flip, and translation/slide) on two dimensional shapes.

Pupils take a field trip to a local park or beach to collect objects. They practice counting the objects and put them into categories according to type of shape like a cone, cylinder, etc... As an extension to the lesson plan students...

Time to move into the third dimension! Learn the names of the geometric solids and count faces, edges, and vertices. Then learn to recognize nets that create a given solid. 

Learners examine objects and find their volumes using geometric formulas in the 21st installment of this 25-part module. Objects take the shape of truncated cones and pyramids, and individuals apply concepts of similar triangles to find...

Everything old is new again. The Los Angeles J. Paul Getty Museum presents a lesson on how Greek black-figure painting influenced eighteenth century Neoclassical artists. After looking at a series of examples, class members create their...

Why are only four colors needed to color webs from regular pentagons, not five? An assessment task requires young mathematicians to first construct regular pentagons using a compass and straightedge, then has them consider a shape...

Math scholars study conics and how they are used today. In this mathematical lesson, pupils construct and slice cones after viewing a demonstration. 

Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory lesson.

Examine patterns of figures composed of six-squares and predict which of the twenty presented could be folded to make a cube. They then fold large-scale patterns of these figures to confirm their hunches.

Young artists build a three-dimensional form with Twisteez Wire on a stationary screen base. They can paint the base if they wish. The results of this art project are spectacular, but be warned that the materials needed are not easy to...

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

Use a Platonic solids worksheet to record the number of faces, edges, and vertices of five polyhedra whose faces, edges, and vertices are all identical. For each figure, learners write a proof of Euler's formula (F+V=E+2). They create a...

Have your class participate in a variety of sports and craft activities using this resource. With sports as the theme, learners work on art projects. Young scholars create soccer ball prints, a three dimensional football, and a sports...

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 measurements by analyzing geometric shapes. In this surface area lesson plan, students identify the terms volume, weight, perimeter and area in order to find the requested measurements of specific polygons. Students...

Second graders make boats by folding paper. They identify and draw shapes made during the creating process and place lines of symmetry on them. They demonstrate their understanding by completing an activity sheet imbedded in this plan.

Sixth graders explore different polygons. In this polygon lesson, 6th graders examine a rhombus, quadrilateral, parallelogram, and rectangles. Students compare and contrast polygons and research shapes on the Internet.

Students investigate two and three dimensional shapes. For this geometry lesson, students write equations of circles and graph them correctly. They create pictures using circles.

Students use specific dimensions to create a box. In this geometry lesson plan, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.

Students identify and name basic shapes and points. In this elementary geometry lesson, 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 the...

Third graders examine two-dimensional objects and create a 3-D image of the object. They make models of the Taj Mahal and buildings in Delhi.

Fifth graders will be predicting and describing the results of sliding, flipping, and turning two-dimensional shapes. They will also understand patterns so they can describe, extend, and make generalizations about geometric and numeric...
