Students mix tens and hundreds rounding in one go, which is exactly the kind of thinking real estimation requires. Part A's nine fill-in-the-blanks bounce between rounding 64 and 92 to the nearest ten, taking 317 and 673 to the nearest hundred, and estimating sums like 27 + 54 and differences like 76 - 29. Part B is a four-pair matching set with numbers like 83, 350, 512, and 46 finding their rounded partners.
Switching between tens and hundreds in one sheet trains kids to slow down and ask which digit matters before answering.
