More discussion of comparison of fractions
In class we discussed these examples of student work.
The big take away is that to show you really understand a fraction
comparison, you need to explain both what happens with the size of the
fractional pieces (denominator) and how many pieces you have
(numerator).
If you want to get more practice at noticing what's missing in an explanation, you can check out some examples here (click on the problem to see the discussion of what is correct and what's missing).
