Big Ideas: A fraction describes the relationship between the part and the whole. Comparisons with any model can only be made when both fractions are a piece of the same sized whole. Fractions can be compared using , or = symbols. This lessons builds on students' work with fractions. In this task, students will compare fractions for the type of shots a basketball player makes. By comparing these fractions, students are forced to reason about the size of the fractions and demonstrate their understanding using symbols. 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 numerators. Vocabulary: number line, fraction, equivalent, numerator, denominator, compare, reason, symbols
