Math by the Month is a regular department of the journal, featuring 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 the current issue, mathematics is visible where we least expect it. The use of mathematics gives us a more fruitful understanding of Earth, its animals, and scientific processes. We use math to forecast environmental changes, predict future events, and decide when intervention is necessary to protect the survival of species that are at risk.
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.
