Students continue rounding practice and estimation with a wider variety of numbers. Part A has nine fill-in-the-blank problems including 73, 581, and 46 rounded to appropriate place values. Part B is a matching activity pairing four numbers — 38, 762, 150, and 489 — to their rounded counterparts.
Repeated practice with mixed rounding builds the speed and automaticity needed for estimation in word problems.
