“Fraction is a difficult concept to grapple. Children has just learnt whole numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Now they need to understand fractional parts of whole numbers. Concept of fraction is introduced through fraction set where children play with whole and parts. Once children start understanding, fraction as part of collection is introduced. This is done more effectively on opposite kit. Moving on equivalent fraction is introduced using fraction set. But children do multiple activities on number system to attain proficiency. Various activities on number system are based on addition and subtraction of fractional numbers. This makes complex fractional problems easy and fun to understand. Therefore, this pack contains fraction set, opposite kit and number system.
With concrete pieces of fraction set children can touch and feel whole and part. Children can understand how whole is divided into several parts and how it is represented as fraction al numbers. Further fractional concepts are developed by intuitive approach where children explore and experiment with different fractional parts to discover various concepts. Through fun activities children learn to compare fractions, differentiate like and unlike fraction, make equivalent fractions, do addition, subtraction, multiplication and division of fractional numbers.
Two rulers are made to slide over each other to explain addition as putting together of two numbers and subtraction as taking away of second number from first number. Playing with the ruler helps children to do variety of operations numerous times and hence enhances speed and accuracy. This logic is extended in the other side of sliding ruler to explain addition and subtraction of fractional numbers. Playing with fractional side of number system helps children in understanding and using concept of equivalent fractions.
Double faced counters of opposite kit are used in making different arrangements and collections of numbers. Grouping and regrouping of these counters explains parts of a collection. Suppose there are 12 counters. One third of the whole is 4 counters. “
