This is a pull-and-pop 3D shapes model for math learning.
When you pull the woolen thread, the 2D net pops up and forms a 3D shape.
This helps understand how flat nets convert into solid figures like cube, cone, or pyramid.
It is a fun and interactive TLM (Teaching Learning Material) to teach geometry and visualization.
Materials Required:
- Color paper (thick A4 or chart paper)
- Woolen threads (bright colors)
- Glue or double-sided tape
- Scissors
- Sketch pens/markers (for labeling)
- Ice cream sticks (optional for handles)
- Chart board or cardboard (base)
- Transparent plastic sheet (optional for covering mechanism)
3D Shapes to Include (Examples):
- Cube
- Cuboid
- Cone
- Cylinder
- Sphere
- Pyramid (Square base)
Video Steps to Make the Pull-and-Pop 3D Shapes:
Step 1: Prepare 2D Nets
- Cut out nets of the 3D shapes using color paper (e.g., cube net, cone semicircle + base circle).
- Label each net with its shape name.
Step 2: Attach Woolen Threads
- Punch a small hole at the flaps or edges of each net.
- Thread wool through the holes, so when pulled from the base, the net pops up and forms the 3D shape.
Step 3: Fix on Base Chart
- Stick each net flat on the base cardboard.
- Secure the end of the woolen thread under the base or to an ice cream stick tab.
- When you pull the thread up, the shape pops into 3D.
Step 4: Label and Decorate
- Clearly label each shape.
- Decorate the base with “Pull to Form Shape” arrows.
- Optional: Use a plastic sheet to create a flip-open cover over each shape for protection.
