Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.
Castle Basics
Source Institutions
In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha
Stereoscope
Source Institutions
In this activity, learners construct a device that allows them to view 2-D images in 3-D.
Geometric Solids
Source Institutions
This math activity exposes early learners to a variety of three-dimensional objects. Learners bring geometric solids (everyday objects) from home.
Scaling Cubes
Source Institutions
In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.
Exploring Tessellations (Grades 3-5)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations.
Slimy Cells
Source Institutions
In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.
Cut-Fold-Staple
Source Institutions
In this activity, learners discover how to rotate a flat shape into the third dimension. Learners draw and cut out a shape that has at least one straight edge on an index card.
Exploring Tessellations (Grades 6-8)
Source Institutions
In this activity, learners design unique tiles and make repeating patterns to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.
Geometry Construction: Polyhedral Playthings
Source Institutions
In this activity, learners create 3D geometric shapes using straws and pipe cleaners.
Why Are Two Eyes Better Than One?
Source Institutions
In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.
Geometry and Spatial Relations: It's a Perfect Fit
Source Institutions
In this three-part math activity, learners explore shapes. In part one, learners identify, describe, and classify two-dimensional shapes.
Exploring Tessellations (Grades K-2)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.
Building Three-Dimensional (3D) Structures
Source Institutions
In this activity, learners practice drawing 3D structures in two dimensions. Learners draw cube stacks from five different points of view.
