Product Code : SCL-ML-11966
Decimal Abacus Demonstrates Model (SKU SCL-ML-11966), a decimal abacus demonstration model, uses movable beads to show decimal place value, number representation, counting and basic arithmetic in front of a class. A teacher can move beads position by position to show how a digit's value depends on where it sits. Science Lab Supplies makes the model in its own factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and schools, tutoring centres, contractors and distributors receive it direct from the manufacturer.
Specifications
Movable beads on rods are the working parts of this decimal abacus, and the table lists its details row by row. In short, the teacher assigns a place value to each position before the lesson, so the same demonstration model can show whole numbers, decimal places and simple sums to the whole class.

Applications and Experiments for the Decimal Abacus Model
The decimal abacus can be used to demonstrate positional notation, represent numbers with beads, teach counting and number composition, and model simple addition and subtraction. Because each rod can stand for a decimal place, it helps upper-primary pupils compare values such as tenths and hundredths when decimals are first introduced.
- Primary place value: showing ones, tens and hundreds with beads, then finding the same numbers on a 120 Number Board.
- Decimals: assigning rods to tenths and hundredths to read and compare decimal numbers.
- Number composition: building and breaking down a number bead by bead.
- Arithmetic: modelling simple addition and subtraction, including exchange between places, before practising facts with the Game Numbers and Sums card game.
Standard Scope of Supply
Each order line is one Decimal Abacus Demonstrates Model. Its material, rod count and bead count are stated on the quotation, and a matching student abacus, base ten cubes or place value cards can be itemised alongside it if your class needs them for follow-up practice.
Packing, MOQ and Lead Time
One model can serve a whole classroom, while training colleges may want several. Tell us the number and Science Lab Supplies will quote packing, delivery time and price for it, adding base ten cubes or place value cards if you want them in the same order.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia.

Frequently Asked Questions
How does a decimal abacus show place value?
Each rod is given a place value, such as ones, tens, tenths or hundredths. Moving beads on a rod shows how many of that unit a number contains, so pupils see why position changes a digit's value.
Is this model for teachers or for pupils?
It is a demonstration model for teacher-led lessons and guided exercises in front of the class; pupils can then repeat the steps on desk abacuses.
Is Science Lab Supplies the manufacturer or a trader?
Decimal abacus models are built at the Science Lab Supplies factory in Saha, Ambala, India; as their manufacturer, the company quotes buyers directly, with no distributor between the factory and the school.
How should the model be cared for?
Move beads gently, use the model on a stable surface, wipe it with a soft dry cloth and store it somewhere dry. Supervise younger pupils while they move the beads.
Related Abacus and Place Value Aids
A demonstration abacus is most effective when pupils can repeat the idea with their own materials. The items below add desk-top and upright bead frames, a general abacus model, centimetre cubes, place value cards, decimal number lines and equivalency cubes, so a school can follow the demonstration with hands-on practice.
- Upright Abacus — beads slide along wires or rods set in a frame to represent the decimal places.
- Abacus Desk Table — desk version of the bead calculating instrument, with rods in a frame for decimal places.
- Abacus Model — movable beads on rods or wires for counting, place value and early addition and subtraction.
- Base Ten Cubes — precision cubes measuring one centimetre, for place value and numeration.
- Place Value Cards Model — cards for digit value, number formation and zero as a placeholder.
- Number Cards — colourful, durable plastic cards for units, tens, hundreds and thousands.
- Number Lines — five laminated 5 m lines, including tenths from 0 to 10 and hundredths from 0 to 1.
- Interlock Equivalency Cubes — 51 cubes showing fractions, decimals and percents on their sides.
