Our Differences in Length lesson plan teaches students how to measure objects and how to compare the lengths of two different objects. During this lesson, students are asked to complete an interactive practice activity in which they measure gummy worms with a ruler to the nearest inch both unstretched and stretched and then compare the two lengths. Students are also asked to work on their own to measure 5 different objects of their choosing with a ruler and then compare the lengths of the various objects.
At the end of the lesson, students will be able to measure objects to determine how much longer one object is versus another.
