Steps to make one unit of the origami Jackson cube

Assembling the Jackson cube

STEP 1: Square sheet of paper Students are asked to identify the shape of the paper. How many corners does it have? How many sides does it have? Identify an object having this shape in the surroundings.

STEP 2: Take a square sheet of paper and fold in half vertically. What is the shape obtained? How many sides and corners does it have? Are all the sides equal?

STEP 3: Unfold and bring the left and right sides of the square to the line at the center. What is the shape now? Is it the same as the shape in step 2?

STEP 4: Fold the paper in half horizontally. What is the shape formed now? Is it the same as the square we started with? Is it smaller or bigger than the initial square?

STEP 5: Unfold and then fold the bottom and top edge to the center line. Is this square the same as that in Step 4? Why?

STEP 6: Unfold This is one unit of the cube. Make 5 more units.
