Big Ideas: Fraction models can be used to justify comparisons. Fractions can be compared using the symbols , or =. Fractions can be ordered from least to greatest in order to compare the size. This lessons builds on students' work with fractions. This task uses a scenario in which the LearnZillion moving company is filling up trucks. Students must determine a process for order fractions by determining the largest and smallest fractions first. This will challenge students to compare the fractional amounts of the trucks. By comparing the trucks, students will be forced to reason about the size of the fractions and demonstrate their understanding using symbols and models. In the second portion of the lesson, students will create a math writing piece explaining a map from home to school using data from a chart. Students must do this by reasoning about the size of the fractions to determine which place is the farthest from the home and which is the closest. The mathematical concepts in this lesson build towards students' future work with solving problems that involve comparing fractions by using strategies based on noticing equal denominators. Vocabulary: number line, fraction, equivalent, numerator, denominator, compare, reason, symbols (, =), model Special Materials: manipulatives (as needed) fraction strips
