Number Ruler Set

Addition and subtraction are not just about memorising answers — they are about understanding how numbers relate to each other. The Number Ruler Set makes that relationship visible by letting children slide, count, and discover number bonds on a tactile plastic rail. Simple, clever, and surprisingly effective. 🔢✨

🧩 How to Play:
Slide the ruler to select numbers from the display window. The rail shows how the selected number breaks down into upper and lower components — making number bonds, addition, and subtraction physically visible. Children can explore combinations, verify answers, and develop a feel for how numbers work.

🧠 What Children Learn:
This tool builds number sense, number bond understanding, early addition and subtraction, logical thinking, and numerical confidence. It is especially useful for children who are visual or tactile learners — children who need to see and touch math before it clicks.

👨‍👩‍👧 Why Parents Like It:
At ৳290 it is one of the most affordable brain development tools in the Brain Train collection — and one of the most focused. Compact, durable, and easy to use at home or on the go. A great supplement to school math for children aged 4 and above.

💡 Play Ideas:
Ask "Can you show me 7?" and let the child slide to find it. Then ask "How many ways can we make 7?" — 3+4, 5+2, 6+1. Use it alongside homework to verify answers. For younger children, start with numbers 1–5 and build up gradually.
