Basic Geometry Tools

All the tools you need to create geometric wonders!

Plus you can change the colours of the objects... and hide them.

Motion on Grid

This time you will be describing different ways you can move on a grid.

What do you notice? What do you wonder?

Point, Segment, Circle

This is a special web sketch just for you grade 2/3! 

What do you notice? What do you wonder?

Squares

Use the tools to create a square. Can you make squares within squares? Squares beside squares? See the square designs we created.

Quadrilaterals

Drag the vertices to create different quads. Is it possible to make a square that is not also a rectangle? A diamond that is not also a parallelogram? Why?

Lines à la Mondrian

Perpendicular lines with a purpose. Make your own Mondrian, one that moves too!

Broken Symmetry

Help! I'm not symmetrical... and I want to be. Can you see the line of symmetry? Can you drag the squares so that I'm symmetrical across it?

Triangle Tool

It's imagination time. What images can you create with triangles?

Circle Tool

Here's a challenge for you - can you make a design that uses at least 6 circles that are the same size. Make sure they are exactly the same size!

Spirolaterals

Fractals

A fractal tree you can grow and make sway. What happens at each step? How many leaves?

Lines, Segments & Rays

Hidden Paths

Pi Petals

A circle, a segment, a point: now add motion! Change the speed to make more petals.

Continuous Symmetry

Triangle Shapes

Tessellations

Kaleidoscope

Types of Triangles

Make a Triangle

Discrete Symmetry

Try moving the squares. What happens? Why?

Try to create the images you see to the right of the sketch.

Which images can you make? Why?

Which ones can't you? Why not?

Mean Meets the Median
