I recently created and shared this question on fractions with a year 8 class
I received the following responses. We had a good discussion about decimals in fractions and scales on a number line and also about dealing with fractions with different denominators.
UPDATE!
Here is a match up activity where students have to find the 3 that are not equivalent to the other 9 expressions. Students can discuss cancelling fractions and what can and can not be done when working with fractions
