Big Ideas: Fractions can be modeled in multiple was including a number line. The denominator of a fraction determines how many equal parts into which to partition the whole. This lesson builds on students’ experiences with partitioning number lines and shapes into 2, 3, 4, 6, or 8 equal regions or parts. This task focuses on students using their understanding of partitioning a whole into equal groups to name a unit fraction when given a number line that models multiple wholes. This builds toward students’ future work with multiple representations of fractions in grades 3-5. Vocabulary: unit fraction, numerator, denominator, equal, partition, whole Special Materials: none
