what would be made the low cost TLM for the class room teaching
Answers
Devanik Saha and Nagar Nigam Pratibha Vidyalaya
Devanik realised that unless he could teach students using visual, hands-on material, math would continue to scare them. They needed a way to bring it to life and make it seem more relevant and ‘real’. The potential of this method to make math more accessible to students was brought home to him on the day after his first experiment with straws when one of his students told him she had bought her own bundle of straws in order to revise place values with her friends at home.
Seeing the possibility for children to use the low-cost teaching aids at home, Devanik created a number of resources to teach different math concepts that could be easily sourced at home by his students. These resources are known by Devanik and his students as "Maths in a Box." His aim is that anything he uses to create a resource in his classroom could be picked up by anyone, anywhere in the country.

After implementing this innovation in his classroom, Devanik says that:
“I think the idea has helped me to teach maths visually and has enabled kids to take more interest in maths. I was initially struggling to explain the concepts on the board but now it has helped in teaching better. The low-cost math model should be implemented across all classrooms because it really helps.”
“I liked that there is a lot of emphasis on conceptual understanding in this micro innovation and I have started teaching division using Devanik's method in my class.”
Devanik says that these are challenges we have to manage while implementing the innovation:
“It is sometimes hard to get the students to be sensible and to use the materials to help their learning without being silly.”
“The children need really clear instructions about how to use the materials – otherwise they can end up getting confused."
