In this video, we show how to make an Interactive Number Line Model (maths project) using metal nails, LED lights, wires, and a cardboard base.
This simple DIY project helps students clearly understand:
➕ Positive Numbers
0 Zero
➖ Negative Numbers
➡️ Direction on a Number Line
✨ Touch-Sensitive Maths Learning
How It Works?
Touch the positive number nail → The Positive LED glows
Touch the zero nail → The Zero LED glows
Touch the negative number nails → The Negative LED glows
This hands-on model makes learning fun, interactive, and perfect for maths exhibitions.
