Sutradhar refines and designs teaching aids to meet specific needs. Some teaching aids have been developed to address obvious lacunae in the range – such as recreational maths, special education, and materials with an Indian feel.

Sutradhar also puts together kits that are more comprehensive and help address niche needs. The kits include materials that are readily available, materials that are adapted, as well as some that are specially fabricated. They come with a guide so that teachers can use them more effectively.
