This is an example of some 3D shapes made using isometric paper. Isometric paper looks just like the dots you see in the image. You then draw three dimensional objects onto it, as shown in the picture.
Try to create these shapes with cubes. The one on the left is easy, the one on the right is a little bit harder. They don't have to be the same colours as in the picture. Draw these shapes separately. Create your own shapes on isometric paper.
