DK Find Out! Geometry

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

youcubed: Building Shapes (6-8)
youcubed (Stanford University)

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

youcubed: Building Shapes (3-5)
youcubed (Stanford University)

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

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 (9-12)
youcubed (Stanford University)

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

youcubed: Reduce, Reuse, Geometry (3-12)
youcubed (Stanford University)

Intersecting a 3D shape and a plane might seem intimidating, but a few bottles, a box cutter, and some creativity can give us some insight into what it can look like.

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: Presents
NRICH (University of Cambridge)

Comparing the wrapped presents in this activity will give children the chance to explore and discuss weight, including the idea that large objects aren’t necessarily the heaviest.

NRICH: Tubes and Tunnels
NRICH (University of Cambridge)

When investigating these tubes, children will have the opportunity to practise using everyday language to talk about length, size and position.

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: Building Towers
NRICH (University of Cambridge)

In this task, children will explore 3D shapes when selecting which shapes to use in their tower.

NRICH: Making Footprints
NRICH (University of Cambridge)

In this activity, children will develop an awareness of the faces of 3D shapes by using them to make ‘footprints’ in soft dough.
