In this video, you will learn how to make a colorful and rotating wheel model on Sets for school projects, maths exhibitions, and TLM activities.
This working model helps students understand Union (A ∪ B), Intersection (A ∩ B), Difference, Complement, Universal Set, and Null Set in a fun and interactive way.
MATERIALS REQUIRED
- Cardboard sheet
- Color papers (various colors)
- Black marker
- Glue
- Scissors
- Paper fastener/pin for rotation
- Scale & pencil
- Small circular stickers
- Thermocol/foam board base
STEP–BY–STEP PROCEDURE
1. Make the Base
- Cut a rectangular piece of cardboard.
- Cover it with black and blue color paper (as shown in the image).
- Write “SETS WORKING MODEL” neatly on a small white paper and paste it on the base.
2.Prepare the Stand
- Take a long rectangular cardboard strip.
- Cover it with black paper.
- Fix it vertically on the base using glue and tape for support.
3.Create the Wheel Shape
- Draw a big circle (about 20–25 cm diameter) on cardboard.
- Divide it into 8 equal sections using a scale (like slicing a pizza).
- Cut the circle out.
4.Add Colored Segments
- Cut 8 identical triangular pieces from different color papers.
- Paste each color segment on one division of the circle.
(This creates an attractive pattern like the wheel in the image.)
5.Decorate the Center
- Cut small round shapes (yellow/black combo like shown).
- Arrange them around the center to give a decorative wheel look.
6.Add Set Operation Labels
Make small round/tiny paper circles and write:
- A ∪ B
- A ∩ B
- A – B
- B – A
- U (Universal Set)
- A’ (Complement)
- B’ (Complement)
- Ø (Null Set)
Paste each label on the outer side of colored segments.
7.Attach the Wheel to Stand
- Use a paper fastener (split pin) through the center of the wheel.
- Fix it to the top of the stand so the wheel rotates freely.
