In our school, we also motivate the student for the basic activities like chess, carom, quize, etc.
These all basic indoor games are usefull for the students to improve their mental strength and also for the refreshment of the mind. Children may be inclined to get more associated in their thinking process with materials that are integrated such as math worksheets and chess.
They are more challenged by these kinds of problems. With this kind of deep thinking process, the ability of children in math subjects can be enhanced.
Challenging things are the things that mostly attract the interest of children just like puzzles when they are still toddlers.
