Reflection: Student Feedback Ordering Fractions - Section 3: Guided Practice


Ordering fractions from least to greatest can sometimes be confusing. While it is easy to order whole numbers, fractions consist of a numerator written over a denominator. As long as either the numerator (the number of pieces present) or the denominator (the number of pieces making the whole) has the same value, it is easy to order the fractions.

However, when students are introduced to fractions by dividing them into equal parts they are taught that the lessor the fraction the larger the pieces, therefore, when students began to order the given fractions from least to greatest they initially chose the lessor fraction to be the greatest.   

5/10 would be the greater fraction because it has half of the whole part left, and 3/10 would be the lessor because almost all of the whole is gone.


 Students consider the shaded part of fractions to be the part to give away and the un-shaded part as the part to keep.

**Students need to understand that the numerator (the shaded part in the picture representation) is the part that the problem is dealing with.  It is the part that we are focusing on.  Therefore, we are comparing the part that is on top with the rest.
