All vs. Only Some

For Teachers Pre-K - 2nd Standards
All shapes have certain defining attributes that set them apart from others. In order to understand this, young mathematicians look at examples and non-examples of triangles, rectangles, and squares, working as a whole class to create...

Interactive Geometry

For Teachers 1st - 2nd
Pupils discover the plain shapes that make up space shapes. They match and stamp shapes together, and create their own space shapes. Students apply what they know about space shapes to make amuseum of shapes. Finally, they compare and...

Geometric Shapes Collage

For Teachers K - 3rd Standards
Junior geometers practice stating the names of different geometric shapes. They define and name the different shapes and compare and contrast shapes to one another. They also relate the shapes to objects in the real world.

Module 5: Modeling with Geometry

For Students 9th - 12th Standards
Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Are These Right?

For Teachers 3rd - 5th Standards
Is that a right triangle or a wrong triangle? Young mathematicians look at eleven different shapes and use a measuring tool of their choice to determine which triangles have right angles. Consider cutting out sets of the shapes to...
