Unit 3, Lesson 3

Order three lengths using indirect comparison.

EngageNY 60 min(s)Support for English Language Learners
This lesson extends the use of indirect comparison to compare distances between objects that cannot be moved next to each other for direct comparison. Students use the same transitive process to compare short distances within the classroom in order to find the shortest path to their classroom door, which is helpful to know for lining up and for emergencies. After measuring each path from their desks to the door with the same piece of string, they are able to make statements such as "Maya's path is shorter than the string. Bailey's path is longer than the string. That means Bailey's path to the door is longer than Maya's path." Using grid lines on classroom floor tiles and on provided maps of city blocks, students compare distances of various paths.
