Saravanan from Aikiyam has made maths materials like 1)integer game using number chart and 2 dice.It contains numbers starting from 0 to 89 (both positive and negative side).A target has to be set before starting the game i.e 25 (both positive and negative side). One die contains numbers from 4 to 9.Another die contains three (+) symbols and (-) symbols.Both dice should be rolled simultaneously.The number indicates number of boxes to move while the symbol indicates the direction to move.
2)A tool for Quadrilateral shapes with different angles using scales and pro-circles.
Sanjeev suggested Ganit mala and ganit rack to do integer calculations which should be easy for children to visualize and do calculations faster.
