what is the purpose of using fraction strips and a 1 strip?
Fraction strips are a very useful medium to teach a child about the fundamental theories of fraction. It is very tough for any child to grip fraction fundamentals initially, unless the fractions are broken down. 1 strip or a single strip often confuses the child. So fraction strips like ½, 1/3, 2/3 etc. are used for giving better explanation. When the strips are cut into such sizes and placed beside each other, then it becomes visually easy to see. Then the fundamentals of fractions can easily be explained.
