Virtual PATTERN SHAPES Explore counting, geometry, fractions, and more with a set of virtual pattern blocks.

 The Mathlearningcenter has created a great site for virtual pattern blocks. When you open the site you will see the pattern shapes on left which you can drag over to the board. As you can see in the images below you could show how 4/6 + 1/3 could equal 1 whole as well as how to show dimensions and area.

On the bottom left you can see different tangram shape outlines that you can then try to fill in the shape.

In the example below you can show perimeter and area of different triangles.

I really like this one because you can show how the angles in a triangle are each 60 degrees with the toggle protractor. 

Embedded below is a 2 minute and 50 second YouTube tutorial.

Take care,
