Math by the Month is a regular department of the journal. It features collections of short activities focused on a monthly theme. These articles aim for an inquiry or problem-solving orientation that includes at least four activities each for grade bands K—2, 3–4, and 5–6. In this issue, the problems present opportunities to reason about many mathematical topics, including patterns and grouping, fractions of a set, ratios, and elapsed time.
