Integer Counters
Integer Counters (Product Code: SLE/MAT/42) is a set of two-colour plastic counters used to model positive and negative numbers in school maths lessons and maths labs. Each 30 mm counter is red on one face and yellow on the other, so pupils flip a chip to change its sign while they add, subtract, multiply and divide integers. The counters are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of mathematics lab kits in India, at its own factory in Ambala.

What Are Integer Counters Used For?
Integer counters turn the rules for signed numbers into something pupils can see and move. A common convention is to let one colour stand for +1 and the other for -1. A statement such as -2 + 3 is then modelled by laying out two chips of the negative colour and three of the positive colour, and removing each positive-negative pair as a “zero pair” until one positive counter remains.
Subtraction becomes taking counters away, adding zero pairs first when there are not enough of the colour needed, and multiplication can be shown as repeated groups of chips. Because every counter has two faces, a handful tossed onto a desk also gives a quick first experiment in chance: pupils tally how many land red side up and how many land yellow.
OEM Manufacturer
Integer Counters are produced by Jain Scientific Equipments Private Limited, which trades as ScienceLab, as the original equipment manufacturer (OEM). They are made at the company’s own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana, so schools, maths resource centres, dealers and importers buy them factory-direct instead of through a trading middleman. For vendor registration, tender and institutional buyers can quote GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. More about the company is on the ScienceLab company profile.

Frequently Asked Questions
What colours are the Integer Counters?
Integer Counters are double-sided plastic chips, red on one side and yellow on the other. Teachers usually let one colour represent positive units and the other negative units, and a counter is flipped over to show the opposite sign.
What size are the Integer Counters?
Each Integer Counter has a diameter of 30 mm, which is large enough for small hands to pick up and flip, and for a teacher to arrange clear rows of positive and negative chips on a desk or tray.
Which topics can Integer Counters teach?
Integer Counters support addition, subtraction, multiplication and division of integers, including modelling statements such as -2 + 3 with two-colour chips. The same set can also introduce basic probability, for example by tossing counters and recording which colour lands face up.
How many counters come in one pack of Integer Counters?
The pack quantity of Integer Counters is not stated on this page. Please tell us how many counters you need per pupil or group through the contact page, and ScienceLab will confirm the quantity in its quotation.
Who manufactures the Integer Counters?
Integer Counters are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. New orders, repeat orders and requests for extra counters are all handled directly by the manufacturer.
Can schools order Integer Counters in bulk or for export?
Yes. Integer Counters can be quoted for a single classroom, for bulk orders covering several schools, or for dealers and importers in India and international markets. Send the quantity and delivery location so the manufacturer can prepare a quotation.
How should Integer Counters be cleaned and stored?
Integer Counters can be wiped with a damp cloth and mild soap, dried, and kept in a closed box or bag so none go missing between lessons. Counting them back after each class is a quick way to keep every set complete.
