Fractions As Numbers On The Number Line


Supporting grades: 3

Description: In this 35-day module, students extend and deepen Grade 2 practice with equal shares to understanding fractions as equal partitions of a whole. Their knowledge becomes more formal as they work with area models and the number line. Throughout the module, students have multiple experiences working with the Grade 3 specified fractional units of halves, thirds, fourths, sixths, and eighths. Topic A opens Module 5 with students actively partitioning different models of wholes into equal parts. In Topic B, students are introduced to the fraction form 1/b and understand that fractions are numbers. In Topic C, students practice comparing unit fractions using fraction strips. They specify the whole and label fractions in relation to the number of equal parts in that whole. Students transfer their work to the number line in Topic D. In Topic E, they notice that some fractions with different units are placed at the exact same point on the number line, and therefore, are equal. Topic F concludes the module with comparing fractions that have the same numerator.
