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?
