In this lesson, students work to describe and compare measurable attributes. They compare their linking cube towers to objects. For example, "My 4-stick is shorter than my pencil. My 4-stick is longer than my eraser." Using linking cubes to directly compare different objects is a precursor to being able to compare the lengths of two objects using a third object and order the lengths of different objects in later grades, as well as provide students with a practical context for solidifying their developing number sense.
