You’ll want to avoid using terms like “round up” and “round down” since these terms can be confusing for students. “Rounding up” a number results in a change in the value of the place to which you’re rounding, where “rounding down” does not. Often students will change the value mistakenly as a result.
If you need to adapt or shorten this lesson for remote learning, we suggest prioritizing Anchor Task 1 (benefits from worked example). You might decide to facilitate this Anchor Task and Lesson 11's Anchor Task 3 before assigning Problem Sets from either lesson.
