This lesson is optional because it does not address any new mathematical content standards. This lesson does provide students with an opportunity to apply precursor skills of mathematical modeling (MP4). In previous lessons, students counted collections of objects and represented how they counted. In this lesson students continue to build these skills. Students practice answering “how many” questions without recounting the group of objects. In the first activity, students count a collection of connecting cubes in a way that makes sense to them. In the second activity, they build using the connecting cubes and share what they made and how many connecting cubes they used with their group.
