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 calculate the volume and surface are of three-dimensional shapes. In this geometry lesson, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

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

Students make conjectures of intersecting circles. In this geometry lesson plan, students observe circles and their position in space. They investigate and observe two and three dimensional objects.

Students identify properties of circles. For this geometry lesson, students identify the center of two intersecting circles.They use Cabri software to create circles and move it around to make observation.

Students identify the properties of different polygons. In this geometry lesson, students find the slope of a line and calculate the distance between two lines. They differentiate between similar and congruent polygons.

Students listen carefully and put pieces together following the teacher's instructions. They point to the different shapes and sizes as they are being called out and count the number of items they have in front of them. They decorate...

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

Learners listen to a story "My Crazy Dream" with an intent to identify shapes in ordinary objects. They raise their hands when they've heard an object whose shape they can identify. They discuss their findings.

Students identify various geometric shapes. Apply the given formulas to determine the volume of these shapes. Design their own container to conform to specifications provided. Use their knowledge of volume formulas and shapes to compute...

Students design recreational equipment for a community. In this architecture lesson, students work in pairs to design the equipment. Students select materials and begin designing. Students assess themselves with a pre-made rubric.

Seventh graders participate in a polygon hunt.  In this polygon lesson, 7th graders examine how polygons are alike and different.  Students create a Venn diagram and label the sorting circles.  Students work in cooperative...

Upper graders access the Microsoft Word program and create patterns by utilizing certain keys on the keyboard. They create picket fences, smiley faces, and hearts. It seems that this instructional activity has as much to do with...

Elementary learners explore coin mint dates. First, they listen to the book Alexander Who Used to be Rich Last Sunday by Judith Viorst. They then sort a collection of coins according to their mint date and put them in order from oldest...

In this comparing geometric figures worksheet, learners continue patterns and observe circles. In this problem solving worksheet, students answer seven questions.

Young scholars investigate one, two and three dimensional objects. In this algebra lesson, students differentiate between different shapes of objects and write equations to represent each. They start with what they already know and prove...

Students create a two, three, or four-dimensional collage or assemblage. They use shapes, colors, images, objects, and textures to create their collage.

Students define properties of rectangular prisms. In this geometry lesson, students identify the relationship between two and three dimensional objects. They use Cabri technology to graph their figures.

Students identify the properties of chords. In this geometry instructional activity, students multiply chord segments to find the solution to their problem. They construct two chords that cross on  a circles.

Middle schoolers create 3-dimensional works of art in the form of slot sculptures. I love this lesson, because it exposes students to a completely different form of art. Everything you need to do to successfully-implement this lesson is...

Fifth graders view original artwork, define the art form sculpture, discuss similarities and differences between the examples provided, discuss the three-dimensional quality of each example given, and create and critique their own artwork.

Students find triangles in the real world. In this geometry lesson, students analyze and identify properties of two and three-dimensional objects. They differentiate between similarity and congruence.

Students investigate the properties of two and three dimensional objects. In this geometry lesson, students differentiate polygons based on similarity and congruence. They make observation and interpret the data.

Individuals discover how to draw cubes on triangle-dot paper. They use cubes to build structures and draw corresponding isometric drawings on dot paper in the second lesson of the series of five. The activity also introduces the concept...
