subtraction

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!

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!?

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!

A visual manual on how to use a ganitmala to show whole numbers, add, subtract, multiply and divide them. Also includes how to show the division algorithm for HCF.

A double ganit mala and an open number line can be used to explain the concept of subtraction of integers to students. Swati shows you how. 

Here is a video demonstrating subtraction of multi-digit numbers involving borrowing.

Here is another video from Khan Academy on subtraction.

When do we first introduce children to subtraction? This article follows the sequence of place values and addition operations and is closely linked to the ideas introduced in the preceding articles of this series. 

This video demonstrates an alternate method to subtraction. Practising this will enable your students to mentally subtract numbers.
