Students calculate the area of parallelograms. In this geometry lesson, students identify properties of parallelograms and use to to solve problems. They create polygons using Cabri software.

Learners investigate the side splitter theorem. In this geometry lesson, students estimate and solve problems dealing with ratios and proportions. They identify angles created by lines that are parallel.

In this geometry worksheet, students identify diagrams as either lines, line segments, rays or points, write the definition of each and match it to its diagram. 

In this perspective:  top or front view worksheet, 5th graders look at 3 images of blocks, then choose top, front or could be either view to indicate perspective.

In this math worksheet, students develop their cognitive and motor skills through constructing the geometric solid of a rhombicuboctahedron

Young scholars explore the concept of paragraph proofs. In this paragraph proofs lesson, students make flow charts of the process of getting ready for school. Young scholars convert the flow chart to a paragraph proof. Students use...

Students perform reflections and translations of polygons. In this geometry lesson, students perform reflection in two parallel lines. They use Cabri to observe the transformation and rotations of each shape.

In this math worksheet, middle schoolers construct a paper model of a tetrahedron. They create it to have four triangle faces, four vertices and six edges.

In this math worksheet, students develop cognitive and geometric abilities. They construct a paper model of a octahedron composed of eight triangular faces, six vertices and 12 edges.

Students calculate the measurements of the inscribed angles of a triangle. In this geometry lesson plan, students relate the hypotenuse of a right triangle and the diameter of a circle to each other. They calculate the diameter of a...

In this nets and 3 dimensional figures instructional activity, 5th graders look at the 3D figure and the net and mark yes or no if it is an accurate representation.

In this circle worksheet, students choose the correct term that describes a given set of math symbols, using a labeled circle. A reference web site is given for additional activities.

In this geometric shape perspective worksheet, students look at three images of blocks, then decide if the next image is the top view, the front view or could be either view.

In this 3D figure learning exercise, students observe the net of a 3D figure where you open up the figure and tell if it is an accurate representation of that figure. Students complete this for 3 figures.

In this parts of a circle worksheet, students choose correct terms to identify labeled parts of a circle. A reference web site is given for additional activities.

In this geometric shapes worksheet, students respond to questions that require them to identify chords, radii, diameters and centers of 4 circles.

In this parts of a circle worksheet, learners choose the correct term to describe labeled parts of a circle. A reference web site is given for additional activities.

For this angles and lines:  calculate what is missing worksheet, 6th graders look at four geometric shapes with some information given about angles and lines and calculate the measurements that are missing.

In this math worksheet, middle schoolers read about the truncated tetrahedron and then create a paper model. It should look like a solid comprised of 4 regular hexagonal faces, 4 regular triangular. faces, 12 vertices and 18 edges.

In this math worksheet, students create a paper model of a snub cube. It is an Archimedean solid comprised of 6 square faces, 32 equilateral triangle faces, 24 vertices and 60 edges.

In this math worksheet, students create a geometric paper model of a rombicosidodecahedron solid that is considered a challenging project.

In this math worksheet, students use a paper model to build a truncated icosidodecahedron. The worksheet includes a model that is to be cut out and put together by the student. There is an option to include a small preview of the...

In this math learning exercise, students build a model of a truncated icosahedron. This shape has 12 regular pentagonal faces and 20 regular hexagonal faces. An option to include a preview of the finished model is included for the teacher.

In this math worksheet, students build a truncated dodecahedron. This is a solid shape with 12 regular decagonal faces and 20 equilateral triangular faces. Students build this shape to assist in developing their cognitive and geometric...
