Dash & Dot: Dash Long Jump: Who Went the Farthest? (Gr. 4-5)

Description

Comparing fractions is an essential skill to have in everyday life. In this lesson, students will use Dash to model equivalent fractions on a number line. Students will also compare the values of fractions with like denominators or like numerators.

Objectives

  • Understand that two fractions are equivalent (equal) if they are the same size, or they have the same position on a number line.
  • Recognize simple equivalent fractions.
  • Compare two fractions with the same numerator or the same denominator by reasoning about their size.
  • Record the results of fraction comparisons with the symbols >, =, or <, and justify the conclusions, using a visual fraction model.
