Slide one of the 1/2 beads to represent 1/2
Another way to represent 1/2 is to slide half of another string of fraction beads, for example slide 2 of the 1/4 beads. That is (2 x 1)/4 = 2/4 = 1/2
How many ways can you make 1/2, see the answersheet
Only some of the strings of beads can be used to make 1/2. Which ones? Why? see the answersheet
