A fraction is a number that represents a part of a whole or a set. Place 4 yellow counters. Flip one of the counters red. The red counter represents the fraction 1/4 because there is 1 red counter out of 4 total counters in the set. Make a copy of all the counters. The red counters now represent 2/8 of the set. 1/4 and 2/8 are called "equivalent fractions" because they represent the same parts of a whole. Clear the workspace and then add 15 yellow counters. To find how many counters are in 1/5 of the set, divide the 15 counters into 5 equal groups. Each groups has 3 counters, so 1/5 of 15 is 3.
