-Slide one of the 1/2 beads to represent 1/2
-[[File:Abacus1of2.jpg]]
-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
-[[File:Abacus2of4.jpg]]
-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?
-Find all the ways to make 1/3 and 2/3
-===The Caacupé abacus===
-Load the Caacupé abacus
-It can represent negative whole numbers and fractions. 1/2 can be represented as 1 - 1/2 or 10 - 9 - 1/2
-How many different ways can you represent 1/2 , 1/3, 2/3
-How do you know when you have found them all?
