Unit 3, Lesson 2# Compare length using indirect comparison by finding objects longer than, shorter than, and equal in length to that of a string.

EngageNY 60 min(s)

In this lesson, students begin to use indirect comparison (or transitivity) as they compare each item to one consistent item, such as a piece of string or a strip of construction paper of a specific length. Items are then compared to each other through indirect comparison. For instance, if the crayon is shorter than the paper strip, and the pencil is longer than the paper strip, we can say that the crayon is also shorter than the pencil. As a way to prove their conclusions from indirect comparisons, students use direct comparison to verify their claims.
