problem_activity: Narrative
The purpose of this warm-up is to count on from a given number. As students count, point to the numbers posted so that students can follow along. To support students as they learn to count on, consider asking “What number comes after 3?” or providing a running start by counting “1, 2, 3…” and having students continue the count.
