How many ways can you make 1/2, see the [[Activities/Abacus/Worksheet/Answersheet | answersheet]]
How many ways can you make 1/2, remember you can use 2 strings eg. 1/3 + 1/6 = 1/2
If using just one string, only some of the strings of beads can be used to make 1/2. Which ones? Why?
How do you know if you have found all the solutions?
