• "The lemon law was wonderful as it catered for all abilities. My year 7 top set also enjoyed the fractions adding up to one ninth"

• "We found the 1/27 + 1/27 + 1/27 quite easily, we then had a good discussion at the different denominators. We initially thought it was 1/26 + 1/27 + 1/28 but we did manage to prove this did not work. We eventually found the solution 1/18 + 1/27 + 1/54 using some algebra."

• "My year 7 students cracked this up much faster than I anticipated. Thereafter they were led to write up their own following this pattern.Interestingly they increased the number of fractions and went beyond unit fractions."
