KSDe Standards 2.G.3 Partition circles and rectangles into 2, 3, or 4 equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths.
Students need to be able to interpret different fractions within a shape because it will help them be able to add and subtract fractions in the future. It is important to know what potion of a whole is needed for different situations. For example, bakers need to know what half of one cup is.
