Circle Kit
Circle Kit (Product Code: SLE/MAT/43) is a set of three foam circular discs used to teach radius, diameter and circumference in school maths classrooms. The discs have diameters of 15 cm, 10 cm and 5 cm, so pupils can stack them as concentric circles and compare how the circumference grows with the diameter. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM school lab equipment manufacturer, at its own factory in Ambala, India.

What Is the Circle Kit Used For?
The Circle Kit gives pupils real circles to handle instead of drawings. Stacking the three discs, largest at the bottom and centres lined up, shows concentric circles. Measuring straight across each disc through its centre gives the diameter, and halving it gives the radius, which clears up the common mix-up between the two terms.
For circumference, pupils wrap a string or paper strip once around the edge of each disc, straighten it and measure it. Dividing each circumference by its diameter gives nearly the same value for all three discs, and that constant is Pi. Because the discs are foam, they are light and durable enough for repeated group work, and easy for teachers to pass around the class.
OEM Manufacturer
The Circle Kit is an original ScienceLab product. Jain Scientific Equipments Private Limited, which trades as ScienceLab, is its OEM and makes the kit at its own licensed factory in Saha, Ambala, Haryana. Because the manufacturer deals with buyers directly, schools and distributors can ask the factory itself about repeat orders or replacement discs. Learn more on the ScienceLab company profile.

Frequently Asked Questions
What sizes of discs are in the Circle Kit?
The Circle Kit contains three circular discs with diameters of 15 cm, 10 cm and 5 cm. Having three sizes lets pupils compare radius, diameter and circumference across circles instead of drawing conclusions from a single example.
What material is the Circle Kit made of?
The discs of the Circle Kit are made of foam. Foam discs are light, soft to handle and durable enough for repeated use, which makes them easy for teachers to hand around a class during circle lessons.
Can the Circle Kit be used to show the value of Pi?
Yes. With the Circle Kit, pupils measure the circumference of each disc using a string or strip and divide it by the diameter. All three discs give nearly the same ratio, which introduces Pi through measurement rather than memorisation.
Which lessons is the Circle Kit suitable for?
The Circle Kit suits lessons where circles, radius, diameter, circumference and concentric circles are introduced. Teachers can use it for demonstration at the front of the room or give one kit to each small group for hands-on measuring.
Who manufactures the Circle Kit?
The Circle Kit is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its licensed factory in Saha, Ambala, Haryana, India, and quotations are issued directly by the manufacturer rather than by a reseller.
What should a quotation request for the Circle Kit include?
A quotation request for the Circle Kit should state the number of kits, the delivery city or country, and whether the order is for one school, a tender or resale. Send these details through the contact page so ScienceLab can prepare the quote.
