Geometry is all about lines, angles, shapes, and space.

youcubed: Building Shapes (1-2)
youcubed (Stanford University)

Students work together using a rope to create 2-D and 3-D shapes.

youcubed: Building Shapes (K)
youcubed (Stanford University)

Students work together using a rope to create 2-D shapes.

youcubed: One Cut Geometry (9-12)
youcubed (Stanford University)

The goal is to create 2-D geometrical shapes by cutting them out of a folded piece of paper with just one cut.

youcubed: One Cut Geometry (6-8)
youcubed (Stanford University)

The goal is to create 2-D geometrical shapes by cutting them out of a folded piece of paper with just one cut.

youcubed: One Cut Geometry (3-5)
youcubed (Stanford University)

The goal is to create 2-D geometrical shapes by cutting them out of a folded piece of paper with just one cut.

Illuminations: Patterns and Functions
Illuminations (National Council of Teachers of Mathematics)

Students investigate properties of perimeter, area, and volume related to various geometric two- and three-dimensions shapes.

NRICH: Shapes in the Bag
NRICH (University of Cambridge)

In this task, children put their hands into a bag and describe what shape they think they can feel and why.

NRICH: Exploring 2D Shapes
NRICH (University of Cambridge)

In this task, children will make shapes out of loops of string and discuss what they notice about their shapes.
