Mathematical balance
Product Code : LSK-ML-10093
Mathematical balance (SKU LSK-ML-10093), often called a number balance, is an 8.5-inch (about 21.6 cm) tall balance supplied with twenty 10 g weights. As pupils add weights and watch the beam level, they see number operations, equations and the properties of arithmetic in a concrete way. Primary and middle-school maths teachers use it for number relationships and early algebra. Made at the Science Lab Supplies factory in Saha, Ambala (Plot 448, HSIIDC Industrial Area), it is sold directly to schools, contractors and distributors.
Specifications
The set pairs a compact 8.5-inch balance with a matched set of twenty 10 g weights, so every weight counts as one equal unit. Placing weights on either side and checking whether the beam balances turns a written statement such as 3 + 5 = 8 into something pupils can test.

Applications and Experiments for the Mathematical Balance
A level beam means both sides are equal, which gives children a physical meaning for the equals sign. Teachers use the balance to show that addition can be done in any order, to find a missing number, and to introduce the idea of solving an equation by keeping both sides balanced.
- Primary number work: addition facts and number bonds.
- Commutative property: showing that 4 + 6 balances 6 + 4.
- Missing-number problems as a first step towards algebra.
- NCERT Class 6–7 simple equations in CBSE maths lab activities.
Standard Scope of Supply
Each set contains one 8.5-inch mathematical balance and twenty 10 g weights, ready for use in class. Extra weights or other maths lab manipulatives are not part of the set; if you need them, they can be listed on the quotation alongside the balance.
Packing, MOQ and Lead Time
Enquire for a single set or for one per group across several classes. The quotation lists packing, delivery time and price for exactly that quantity, and matching items from our maths lab equipment range, such as counters or Cuisenaire rods, can be added.
Science Lab Supplies holds an Importer-Exporter Code as a registered exporter and is able to ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. Start an order in the enquiry cart, ask questions on the contact page, or read about tender supply on the lab tender page.
Frequently Asked Questions
What comes in the set?
One balance, 8.5 inches tall, and twenty weights of 10 g each. The equal weights let pupils treat each one as a unit when building and comparing numbers.
How does it help with algebra?
Pupils see that an equation stays true only while both sides balance, so finding an unknown becomes a matter of adding or removing weights until the beam is level again.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures the balance itself, at its factory in Saha, Ambala, India. Buyers therefore deal with the maker, and quotations are prepared directly by the factory team.
How is it different from the simple beam balance?
The mathematical balance is designed for number and equation work with equal 10 g weights, while the simple beam balance has detachable buckets and a sliding compensator for teaching mass and measurement.
Related Balances and Number Aids
These four items extend the balance into measurement and number work. The two other balances move pupils from equal-unit comparisons to measuring real materials, while counters and Cuisenaire rods let them model the same number relationships on the desk before testing them on the beam.
- Simple Beam Balance — plastic balance with detachable buckets for mass lessons.
- Rocker Bucket Balance — compares weight and volume of solids and liquids.
- Plastic Counters Colour — 100 counters in four colours for counting and sorting.
- Cuisenaire Rods — rods of various lengths for addition to fractions.
