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 activity, students draw a shape based on the directions. They tell the reasons the four resulting circles are concurrent. A sample drawing is included.

Fifth graders examine how to make tessellations. In this tessellation instructional activity, 5th graders review the meaning of the word "polygon" while the teacher shows them various examples. They practice making tiling patterns or...

Students explore tessellations and the artwork of M.C. Escher. They view and discuss a video about M.C. Escher, create a slide template out of cardboard, and create a poster with their tessellation pattern.

Students examine a selection of shapes and identify which shapes tessellate and why. They design and make a pattern which involves translation, reflection, or rotation. Students describe the features of 2-dimensional and 3-dimensional...

Tenth graders calculate the area of various shapes. In this geometry lesson, 10th graders use isometric paper to draw shapes. They identify their shapes by name and calculate how many triangles will fit in the area of a shape.

In this polygons instructional activity, students put a polygon jigsaw puzzle back together to form the planet Earth. Students put 10 polygons together.

Fifth graders create polygons requested by their teacher. For this polygons lesson, 5th graders watch a video and listen to a song about polygons. Then, students take turns labeling various polygons and practice making polygons.

Fifth graders work with polygons.

Pupils study geometric shapes, lines, and the primary colors as they create Mondrian-like art prints.

Fourth graders participate in what is considered to be a model lesson. The lesson focuses upon polygons and basic geometry. The lesson addresses national standards and displays how others should be done.

Seventh graders investigate the area and volume of 2D and 3D figures. In this geometry lesson, 7th graders create a storyboard explaining their knowledge of 2D and 3D shapes. They analyze their data and interpret their...

Students construct the tangram pieces from a square paper by following directions to fold and cut. They make observations on the pieces formed and compare how they are related to each other. They explore patterns and shapes with the...

Students explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on students.

Students create a glossary of geometric terms while exploring tangram manipulatives.

Fourth graders explore polygons. In this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.

Third graders describe an amount of turn from a particular position to another using the 'circular' benchmarks of 0, ++, ++, ++, and full turn. Estimation language such as 'just about', 'between', 'not quite', 'just over', and similar...

Learners explore volume and surface area. In this math lesson plan, students fill boxes with cubes to identify the volume of the boxes. Learners discuss area.

In this perimeter instructional activity, students complete a set of 10 short word problems that define certain measurements and ask for perimeter. A reference web site is given for additional activities.

The Golden Ratio. The Divine Proportion. Yup. It's math and art blended into one colorful activity. Young artists combine colored tissue paper circles and parts of circles to create geometric patterns. As a bonus, kids get to figure out...

The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.  

For this rigid transformation worksheet, students follow directions to translate, reflect or rotate a figure in a coordinate plane. Examples and explanations are provided at the beginning of the document. This two-page worksheet contains...

Learners investigate the symmetries of a convex quadrilateral in a collaborative activity. Rigid motion and complements are explored as learners analyze different cases of reflections across a line.
