It is difficult for most students to look at a flat pattern of connected squares and tell whether it will fold into a cube. This lesson presents a new approach which makes it much easier for students to accomplish this mental task.

This free interactive video starts by presenting the new approach.
The video lesson then allows students to interactively practice forming two-dimensional drawings composed of squares into cubes and distinguishing which drawings can make a cube and which cannot. This lesson is suitable for use with both Smart Boards and video projectors and allows the children to participate in the lesson by working appropriate problems.
