Sorting Kits Triangle
Sorting Kits Triangle (Product Code: SLE/LP/16) is a set of different types of triangles in three colours, used to develop geometric thinking by sorting and classifying triangles in school maths. Groups of up to 4 children aged 8–14 years sort the pieces in different ways and look for the geometric basis of each grouping, moving from how a triangle looks to what defines it. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as one of its mathematics lab kits for geometry teaching.

What Is the Triangle Sorting Kit Used For?
A first sort is often by colour, and that is useful precisely because colour turns out not to be a geometric property. The teacher then asks for new sorts — by equal sides, by the largest angle, by whether there is a right angle — and children discover the categories equilateral, isosceles and scalene, and acute, right and obtuse, for themselves.
Laying one piece over another is a direct test of congruence, while comparing triangles that share a shape but not a size introduces similarity. Tracing a triangle on paper, tearing off its three corners and fitting them along a straight line shows the angle sum property in a way pupils remember. Together these activities move children from recognising triangles by sight to reasoning about them.
What to Specify When Ordering
- Which kit you need: triangles (three colours), quadrilaterals (Sorting Kit Quadrilateral, two colours), or both.
- The number of kits — each serves a group of up to 4 children.
- A request to confirm the number of pieces and their material in the quotation.
Supplier
Sorting Kits Triangle is supplied by Jain Scientific Equipments Private Limited, the Ambala company behind the ScienceLab brand. Upper-primary and middle schools, maths labs and dealers in India and international markets order it on its own or with the quadrilateral kit. More about the company is on the profile page.

Frequently Asked Questions
What is in the Sorting Kits Triangle set?
Sorting Kits Triangle is a set of different types of triangles made in three different colours, designed for sorting and classification activities by groups of up to 4 children aged 8–14 years.
What concepts does Sorting Kits Triangle teach?
Sorting Kits Triangle teaches the properties and classification of triangles, the angle sum property, congruence and similarity, and relationships between shapes, helping children move from recognising triangles by appearance to describing them by their properties.
How many triangles are in Sorting Kits Triangle?
The number, sizes and material of the pieces in Sorting Kits Triangle are not given in the product description. Please ask through the contact page, and your quotation will list the pieces supplied in the set.
Is there a matching quadrilateral kit for Sorting Kits Triangle?
Yes. Sorting Kit Quadrilateral is the companion to Sorting Kits Triangle, with different types of quadrilaterals in two colours for the same 8–14 age range, so both kits can be used across one polygon classification unit.
Who supplies Sorting Kits Triangle?
Sorting Kits Triangle comes from Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, which supplies schools, maths labs and dealers in India and international markets with single kits or group quantities.
