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: Fold across a diagonal (Bring one corner to the opposite corner and fold)
 What is the shape that results?
 How many corners does this shape have? Compare with that of square.
 How many sides does this shape have? Compare with that of square.
 How many triangles are formed?

STEP 3: Unfold, and then fold across the other diagonal (Bring one corner to the opposite corner and fold)
 Students talk about this shape based on the previous observations.

STEP 4: Unfold and then fold the square in half (bring one side to its opposite side and fold)
 What is the shape that results?
 How many corners does this shape have? Compare with that of square
 Are the sides of this shape longer or shorter than that of a square?
 How many rectangles are there?

STEP 5: Unfold and then fold the square in half (bring one side to its opposite side and fold)
 Is this shape same as the previous one?
 Describe the shape.

STEP 6: Unfold. A crease pattern results.
 There are several lines found on the square now.
 Count the number of lines.
 Identify the standing lines and sleeping lines
 Are there any slanting lines?
