Opposite kit: The two-faced counters are used in making different arrangements and collections of numbers. Grouping and regrouping of these counters explains addition and subtraction and relation between them.

Number box: Grouping sticks of number box helps children to understand how numbers are formed in base 10 concept. These understandings enable children to understand concept of ‘carrying’ while adding and ‘borrowing’ while subtracting.
