Big Ideas: Represent two fractions as equivalent by modeling them at the same point on a number line. Equivalent fractions can be generated by adding or removing partitioning lines to number line intervals. This lesson builds on student's understanding of representing whole numbers as lengths on a number line. The task requires students to represent equivalent fractional amounts on a number line.This builds toward student understanding of comparing fractions. Vocabulary: numerator, denominator, equivalent, fraction, number line diagram, point, partition, whole, interval, unit fraction Special Materials: None
