In this blog given the detailed instruction on making of Geometric Shapes Math’s TLM Working Model for B.Ed

Creating a Geometric Shapes Math’s TLM Quiz working model using LED lights, a 9V battery, and nails can be an exciting and interactive way to engage students in learning about different shapes and their properties.

Let’s build a simple quiz model where students can identify geometric shapes by illuminating the correct LED light corresponding to the shape.

Materials needed:

- Cardboard or thick paperboard (to create the base)
- LED light
- 9V battery or a battery holder with appropriate connections
- Nails or metal thumbtacks
- Electrical wires
- Insulating tape
- Color paper or markers (for labeling shapes)

Step-by-step instructions:

- Base and Shape Cutouts:
- Cut a large rectangular piece of cardboard to serve as the base of the quiz model.
- Cut out several shapes from colored paper or cardboard. You can include various geometric shapes like triangle, square, rectangle, circle, pentagon, hexagon, etc.

- LED Connections:
- Connect the positive (anode) and negative (cathode) leads of each LED light to electrical wires. Use insulating tape to secure the connections properly.
- Attach one end of each wire to the appropriate leg of the LED lights, ensuring each color represents a different shape.

- Battery Connection:
- Connect the free ends of the electrical wires from the LED lights to the positive and negative terminals of the 9V battery or battery holder.

- Labeling the Shapes:
- Label each shape on the base using color paper or markers. You can write the shape’s name next to where the LED representing that shape will be placed.

- Nails as Buttons:
- Insert nails or metal thumbtacks into the cardboard base near each shape’s label. These will serve as “buttons” that students can press to answer the quiz.

- Quiz Functionality:
- When a student wants to answer a question about a shape, they will press the corresponding nail (button).
- Pressing the nail completes the circuit and lights up the LED representing the correct shape if the answer is correct.
- If the answer is incorrect, no LED will light up.

- Conducting the Quiz:
- Present questions to the students, asking them to identify different shapes.
- Students can press the corresponding nails (buttons) to answer the questions, and the correct answers will be illuminated.

This Geometric Shapes Math’s TLM Quiz working model using LED lights, a 9V battery, and nails provides a hands-on and interactive approach to learn about different shapes and their properties while making the learning experience more enjoyable and engaging.
