Big Ideas: Visual models can be created to represent fractional parts that are equivalent. Equivalent fractions can be generated by adding or removing partitioning lines to shapes. This lesson builds on students’ understanding of unit and non-unit fractional amounts. The task encourages students to represent equivalent fractions using visual models. Students discover how to generate equivalent fractions by adding or removing partitioning lines to models. This lesson builds toward students' understanding of generating fractions using area models. Vocabulary: equivalent fraction, numerator, denominator, part, whole, visual model, partition Special Materials: None
