Fractions - Tricky Bits and Misunderstandings

Fractions - Tricky Bits and Misunderstandings

Here are some common problems children can have with fractions:

1) The language of fractions trips them up:

Fraction word
Order / Numbering Word
a whole
first
half
second
third
third
quarter / fourth
fourth
fifth
fifth
sixth
sixth
seventh
seventh

See how the same word is used with two different meanings: sixth, seventh, eighth, tenth . . . . this can cause a lot of confusion early on.

2)  Dividing into three parts doesn't always make a third.

Take this "cake" - whoever got the first slice would be very happy!

The parts must be equal to be thirds!

3) Thinking that fractions always have the same shape:

Learners are used to seeing fractions like this:

But they sometimes don't realize this could also be a fourth:

4)  Getting mixed up between a "fraction" and a "fraction of a number"

Young learners can get their head around the idea that a half is bigger than a fourth.

However, tell them that one fourth of 200 is bigger than one half of 50 and you may see the confusion in their faces. Again this is a language issue because learners don't pick up on the big difference between "one fourth" and "one fourth of..."

How can parents help?

1) Never miss a chance to get your child using fractions at the dinner table or when baking in the kitchen.

2) Listen and talk to your child about fractions. For ages 4 to 6 this will be about the common fractions - halves, fourths/quarters, thirds.

3) As children get older they'll start simplifying and adding fractions - to keep up with this, sign up to our blog to stay up to date with how to support your child as they learn.
