Mathematical balance
Product Code : LSK-ML-10093
Mathematical balance (SKU LSK-ML-10093), also known as 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. It suits primary and middle-school maths classes working on number relationships and early algebra. Science Lab Supplies builds the balance at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and quotes schools, contractors and distributors from that factory.
Specifications
The number balance set is broken down row by row below. In short, an 8.5-inch balance is paired with a matched set of twenty 10 g weights, so every weight counts as one equal unit and a written statement such as 3 + 5 = 8 becomes 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. The balance can show that addition can be done in any order, help pupils find a missing number, and introduce the idea of solving an equation by keeping both sides balanced.
- Primary number work: addition facts and number bonds, practised further with the Game Numbers and Sums card game.
- Commutative property: showing that 4 + 6 balances 6 + 4, then matching the same sums with Dominoes Colour.
- 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. If you need extra weights or other maths lab manipulatives, they can be listed on the quotation alongside the balance so that one delivery covers every group.
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. For a price on number balances, write in on the contact page with your group count, move the set into the enquiry cart, or look over the lab tender page for formal tenders.
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 on either side of the beam.
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?
Each number balance is made in Science Lab Supplies' factory at Saha, Ambala, India, so the company is its manufacturer; buyers deal with the production team directly, with no trader in between.
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 items extend the balance into measurement, lever and number work. The other balances move pupils from equal-unit comparisons to measuring real materials and studying levers, while counters, rods and cubes let them model the same number relationships on the desk before testing them on the beam.
