About Fraction Misconceptions
Where do fraction misconceptions come from?
Part of the answer is worksheets and or limited experiences with creating fractions.
We have chosen the Usborne Lift-the-flap Fractions and Decimals book to share a section with you.
Most worksheets for fractions give a shape and ask that a quarter or other fraction be shade.
There is a lot wrong with this type of approach if:
- the quarters are always shown in the same way,
- no emphasis is given to counting to find out how many quarters are not shaded,
- students are never exposed to lots of diﬀerent ways of making quarters and justifying how they know that they are quarters,
- students are never asked to visually construct the rest of the shape to identify the fractional part, as in:
With all of this in mind, we have selected this section of a page in the Lift the flap book.
This is quite a clever section because it does challenge the way in which fractions as equal parts is usually presented and leads to using two equivalent fractions to create a quarter and in the last example requires visualization to identify the missing part. When the flaps are lifted the diagrams reveal the proof that they are indeed each showing a missing quarter.
Imagine setting the students free to create their own lift the flap fractions with the proof shown diagrammatically underneath. We usually oﬀer Post-it notes for this type of activity. The kids think they are really special.
