## Using Ten Frames inside your Classroom

Ten-frames are relatively new to India. They are very useful at the beginning for learning the single-digit numbers. They also facilitate automatization of addition facts with single digit numbers. In addition, they can provide a lot of conceptual clarity wrt odd-even.

Three versions are included:

## Making Ganitmala

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!

## Making Multiple Versions of Flats-Longs-Units to Teach Numbers and their Operations

2D base 10 blocks, popularly known as Flats-Longs-Units (FLU) are the most useful of all manipulatives for numbers. They can be extended to decimals through fractions as well as to algebra tiles.

These pre-grouped proportional manipulatives can be used to introduce numbers up to 999 and the four operations - addition, subtraction, multiplication and division. In fact, they can be used to understand the division algorithm to find the square root!

## How to Make Nets of Solids from Everyday Materials

Nets of solids can be used to make 3D shapes from posters or chart papers. Stage-wise list of solids and how to make them along with diagrams are included.

## How to Make a Low-cost Fraction Kit

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

## History of Microbiology

The story of Microbiology comes handy for a teacher to help build context of the kind of risks researchers take which in the longer run was hugely beneficial to the humankind. Stories of this kind help them see the underlying principles of how human body works and how it responds to pathogens.

## Make a Toy Fan Machine

Children love to play with rotating toys. How about making one, with the children with everyday materials?

Materials required: string, hollow plastic ball (any pipe with one end close, hollow bamboo with one end closed), thin bamboo stick (or barbecue stick), ice cream stick (or anything similar)

## Representing Numbers

This worksheet makes the kids play with numbers and appreciate how these numbers (1-9) can be represented in different ways. Please add your feedback, especially after using it in your classroom.

## Learning Area and Perimeter through a Story

Stories are no new to the children.Children had always liked stories and as they grow up they love to enact the same.But as the children grow up we feel that stories are not necessary anymore but in reality,stories and the interest towards stories is never ending.

As discussed in the earlier post,word problems are the ones which play a major role in creating fear towards the subject.Now lets see how stories can be used to make a child understand a word problem and the concept related to the topic.
