As ever, the Nrich resources are well thought out. This one looks at a simple rule for writing fractions as a sum of unit fractions. Could easily be turned into a whole lesson or just used as part of a lesson on fractions.

Nice enrichment activity with a history connection for addition and subtraction of fractions with unlike denominators.
