Represent fractions visually using shape models. Scholars color in two sets of shapes to represent specific fractions: 2/3 and 3/4. The shapes are segmented into equivalent fractions for most of these, so scholars need to understand this concept (or discover it as they go). For example, one shape is divided into 12 parts and scholars color in eight to represent 2/3. Can they tell you the fraction represented by the remaining shapes?
