Unit Overview

Number puzzles help students develop their own problem solving methods.
Many students may have difficulty with abstract mathematical problems and
hence, it is difficult to guide them. Number puzzles and connecting lines
puzzles will allow students to develop a positive perception and attitude
towards math. This positive development will serve as a foundation for
progress in the creative and critical thinking skills of the students.
