GEO Board

It is powerful teaching aid in maths at secondary as well as higher secondary level. Various concept in geometry like shapes, their perimeters, their areas, also concepts in algebra like number system and Cartesian co ordinates system can be taught very effectively with geo – board.

Circular Geo - Board

It is multipurpose demonstration tool for verifying many basic concepts in geometry specially theorems concerned to circle.

It is an octagon circum scribed by a circle. Eight pegs are fixed as the vertices of the octagon and there is a peg at the center representing the center of the circle. There are moveable protractor fixed with each peg.

Solids Of Revolution

This model helps you to observe the shape of virtual solids obtained by revolving different geometrical shapes around an axis. The following geometrical shape come with model
1. Triangle
2. Rectangle
3. Semi circle
4. Area of parabola

Hyperbolie Curve

Pythagorus Theorem

An easy technique to demonstrate the result a²+b²=c² in a right angled triangle, just by clear assembly of a² and the pieces 1,2,3 and 4 of b² together giving you c²

Algebra Kit 1

Is I becoming very difficult for you to remember algebraic identities. Make an easy path to understand all the identities verified practically using a Kit of identities in algebra which does not allow you to forget the identities . With this kit you can verify the identities
1. x(a+b)= ax+bx
2 . (a+b)² = a²+b²+2ab
3. (a+b+c)²=a²+b²+c²+2ab+2bc+2ca

Algebra Kit 2

With this kit you can verify the identities
1. a²-b²=(a+b) (a-b)
2. (a-b)²=a²+b²-2ab
3. (a-b-c)²=a²+b²+c²-2ab+2bc-2ac

Area Of Circle

Wandering how to set area of circle which does not have any line segment ! Here is an amazing tool which just uses the sector and area of parallelogram to set the area of circle πr²
