Fraction

Fractions can be modeled in various ways. The model with the square as the whole turned out to be the most useful. It can be used for everything except reducing a fraction to its lowest form.

Process with diagrams and suggested activities are included.

 

This is "how to make a low-cost fraction kit" inspired by Jodo Gyan (https://jodogyan.org/), Pullouts and other sources. It includes

1. fraction circles and sectors showing unit fractions

2. fractions strips which can be combined to form fraction wall

Fraction additon can be made interesting , easy and fun using this worksheet.

Nothing makes as much sense to a student as his or her own reasoning. And that is why a math class should give students the time and careful facilitation that enables this. The problem at hand was 4/3 + 5/2. Here is an account of a class in which this problem was tackled by students who had understood the need/reason for fractions to be of the same size i.e., to have the same denominators so as to be able to add them easily. However, they had not yet arrived at any particular method to achieve this.

Paper folding techniques have been successfully used to demonstrate multiplication of proper fractions in the classroom. This article may be used to make sense of the same techniques when applied to improper fractions. The problem at hand is to investigate how a product such as 3/2 x 4/3 may be demonstrated by paper folding.

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.

A square paper comes handy when it comes to exploring geometric series & addition of fractions. Try this today.

How can a simple series of folds on a strip of paper be a mathematical exercise? The article, by Shiv Gaur,  describes not only the how but also the why…..based on Fujimoto’s Approximation Method.

Here are some innovative number activities for children that will make them work physically and mentally. And while they are at it, they will be having a lot of fun!
