Learning about shapes sets the stage for understanding geometry. At age six, kids often begin to discover that shapes can be combined or broken down to make new shapes — for example, two squares make a rectangle. They can also move beyond learning about 2D shapes (circles and squares) and explore the properties of 3D shapes (spheres and cubes), as well. Encourage your child to use mathematical language, such as "rhombus" instead of "diamond" or "angles" instead of "corners."

## Support your child's growing knowledge of shapes:

### Go on a Three-Dimensional Shape Hunt

Three-dimensional shapes are all around us, but they might be harder to find than their two-dimensional cousins. Go on a walk around your home or through the neighborhood with your child and try to find as many three-dimensional shapes as you can, including a cube, a sphere, a cone, a cylinder and a rectangular prism.

#### Magical Shape Hunt

A mermaid has lost her jewels and it's up to Peg and Cat to help her retrieve them. While using a net to catch the jewels, your child can practice counting skills and identifying 3D shapes.

### Create Three-Dimensional Shapes with Playdough

Playing with clay or playdough is a great way to explore three-dimensional shapes. Work with your child to see if you can build the following shapes: a cube, a sphere, a cone, a cylinder and a rectangular prism.

#### Secret Message Shapes

Building blocks are a great way to explore 3D shapes with your child. In this activity, you and your child can assemble and take apart 3D shapes, and even use these shapes to send secret messages.

### Play with Tangram Puzzles

Tangrams are ancient Chinese puzzle pieces, and they are a great way to explore shape composition and decomposition! Print out your own here, or the next time you eat a sandwich, use it as a learning experience!

### Teach Squares vs. Rectangles

Using graph paper, have your child draw both a square and a rectangle. Discuss why they are different and why they are the same. Can your child draw a rectangle made out of two squares? Emphasize that a square is a special kind of rectangle that has an equal length on all sides.

#### Sort and Spot the Dangerous Doobles

The Doobles are on the loose, and agents must work together to quickly find them all and put things right again. Your child can help the Odd Squad by identifying, sorting, and classifying unique features of the creatures to crack the case.
