# how to make Geometric Shapes Math’s TLM Working Model for B.Ed

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:

1. Cardboard or thick paperboard (to create the base)
2. LED light
3. 9V battery or a battery holder with appropriate connections
4. Nails or metal thumbtacks
5. Electrical wires
6. Insulating tape
7. Color paper or markers (for labeling shapes)

Step-by-step instructions:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
