Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.
Reflections
Source Institutions
In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.
Exploring Tessellations (Grades 3-5)
Source Institutions
In this activity, learners repeat patterns in two and three dimensions to create tessellations.
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.
Mold Mole Molds
Source Institutions
In this activity, learners make different shapes that hold exactly one mole of gas (air).
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.
Tangram Challenge
Source Institutions
In this activity, learners use tangrams ( 7-piece puzzle tiles) to assemble a variety of shapes. Tangrams are ideal for improving spatial reasoning and geometry properties.
Toothpick Patterns
Source Institutions
In this hands-on activity, learners use toothpicks to build different triangles and squares and then use the toothpicks to build and solve some tricky shape puzzles.
Simple Pop-Up Mechanisms
Source Institutions
In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.
Patterns and Relationships: The Magic Box
Source Institutions
In this math lesson, learners participate in a variety of activities that give them experience in recognizing, describing, and extending repeating and arithmetic patterns.
Making a Translation Tessellation
Source Institutions
In this activity, learners slide shapes to create unusual tiled patterns.
Fun with Shapes
Source Institutions
In this activity, early learners combine pre-cut recognizable shapes and their own abstract ideas to make representational pictures (e.g. houses, trees, shoes).
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.
Rotating String Shapes
Source Institutions
In this group activity, learners make multi-sided polygons with string.
