division

Ganitmala is a manipulative version of number line. It is a proportional material that has properties of both groupable and pre-grouped models. Jodo Gyan (https://jodogyan.org/) introduced them in India.

It can be used for introducing whole numbers and all four operations - addition, subtraction, multiplication and division. It can also be used for the division algorithm to find the HCF!

A fraction calculator that can perform addition, subtraction multiplication or division of two fractions. Simply enter the values directly into the corresponding locations and the answer will be updated in real time.

Swati shares a game from Swanirvar/Shikshamitra that assesses number operations and demands higher order thinking skills. Did we tell you that it is a cheating proof game!?

The denominator in a fraction is a stumbling block for every first time learner. 3 is bigger than 2. But 1 upon 3 is smaller than 1 upon 2. Try explaining this to a child! Rupesh Gesota in his blog didn't try that. Rather he led the child into a trap of confusion knowingly! 
Sharing the conversation that he jotted down on his blog.

Here is a quick rewind of some interesting ideas that got featured on the Teachers of India website. We know it is not final. We know there are very many resources you found it useful that we couldn't feature in this particular list. How about you making your own list and sending it to us. We also invite you to remix ideas from your own experience and share it with larger teacher community. That would be a great bang to start the year!

"There is no difference between living and learning... it is impossible and misleading and harmful to think of them as being separate.” ~ John Holt
