How Long Are We?

Massachusetts Department of Elementary and Secondary Education 53 min(s)

In this lesson, children get a chance to see that this place-value concept can be applied to a measurement task; namely, that breaking a Unifix train into bundles of ten allows them to quickly determine how many Unifix cubes tall they are. Students also place their recorded heights on a number line, another tool that facilitates comparison of numbers. As you plan, consider the variability of learners in your class and make adaptations as necessary.
