## Addition practice game

Here is a game that reinforces your learners to find out which 2 numbers to add to get the same result.

## Conics, Paper folding, Geogebra II

In this article we shall describe the construction of the ellipse and the hyperbola using a similar strategy of paper-folding followed by a Geogebra exploration. The reader may consider the previous article as a pre-requisite to this one.

## a cube plus b cube explained visually

Swati Sircar invites you to explore the cubic identities a^3 + b^3 through models.

## a cube minus b cube explained visually

Swati Sircar invites you to explore the cubic identities a^3 - b^3 through models.

## Life of Pi, mathematically speaking

Pi - the irrational, nevertheless mathematical, constant and “celebrity number” (as Alex Bellows puts it) is an intriguing & insπring number that has enthralled mathematicians for centuries.
How can I show this to the uninitiated?

## a plus b whole cube explained visually

Swati Sircar invites you to explore the cubic identities (a+b)3 through models.

## a minus b whole cube explained visually

Swati Sircar invites you to explore the cubic identities (a-b)3 through models.

## Sari Folding & the Powers of 2

Remember, as a child, being amazed at how neatly adults could fold long pieces of cloth? Why not make a lesson out of this?
Swati Sircar, in this video, demonstrates how the powers of two can be learned from folding a sari. Now, try it in your classroom!

## AtRiA Paper Play - Making a Skeletal Dodecahedron

Building 3D models to enhance learning. What better way for students to understand concepts like vertices and edges than to construct their own 3D models? Constructing a dodecahedron as demonstrated by Shiv Gaur would personalise their learning in a meaningful way and nothing can beat that experience.
