Free Printables: Nets (3D Models)
For this 3D shapes worksheet, students cut out the 3D shape on the page and fold on the lines to create the correct shape. The worksheet states which shape should be build with the cut-out.
Curated OER
Rectangular Prism Net
In this geometry worksheet, students cut out a rectangular prism net. They cut along the dotted lines as indicated the scissors icon, and fold the piece along the solid lines to form the three-dimensional shape. There are no directions...

Cut It Out!
Students calculate the surface area of polygons. In this geometry lesson, students use spacial reasoning to find the answer to their problem. They analyze solids and create formulas to estimate the measurements of the area.
Curated OER
Net (Cone)
In this cone worksheet, students cut out, fold and assemble a solid figure of a cone by using the net provided on this page. No written directions are given.

Chopping Cubes
Middle schoolers work in small groups to make various geometric solids with Play-Doh. They use fishing line to make cuts and observe the shapes of the cross-sections. Pupils complete an assessment in which they answer questions such as:...
Curated OER
Two for One Box Company
Students draw a net (a two-dimensional pattern that can be formed to make a solid) for making an open top box on grid paper. They cut out the net and fold up each side to form the open box and tape the sides, then find the volume of the...
Curated OER
Net (Triangular Prism)
For this net worksheet, students use the pattern to create a triangular prism. Students cut out the pattern and fold on the dotted lines and paste it to make the solid figure.
Curated OER
Area of Solids
Students find the area of rectangular solids and cylinders by cutting them into flat pieces and adding the areas.
