Not using the complete set of objects
¼ of the balls are blue..That means 1 ball is blue
and 4 are not.
Not appreciating the denominator
I think ¼ is bigger than ½ as 4 is bigger than 2. I can put
these fractions on a numberline
0 ½ ¼ 1
Not appreciating the numerator
I know that a quarter is smaller than a half. So ¾
must be smaller than ½ as we have shared into 4
pieces of pizza
Confusing halving and doubling
Halving is something to do with the number 2. Half of
my sweets must be 12
