This problem provides an interesting context to consolidate addition of fractions and requires students to develop and analyze different strategies and explain their findings. Students are asked to find a general method for expressing unit fractions (fractions which have numerators of one) as the sum of two different unit fractions. They also explore whether all unit fractions can be written like this in more than one way. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, and ideas for extension and support.
