In this Scooping Up Hundreds Rounding Activity, students use place value understanding to round whole numbers to the nearest 100.
Closer to which ten? Let's find out
Third graders learn to round whole numbers to the nearest 10 or 100. Rounding means finding which "friendly" number is closest: 47 sits between 40 and 50 and is closer to 50, so 47 → 50. For hundreds, 362 sits between 300 and 400, and since it's past the halfway point of 350, 362 → 400. The halfway rule: 5 and up rounds up. Kids use rounding to estimate answers and check if their math makes sense. The click comes when a child sees a number line and just knows which way to go.
Rounding makes sense on a number line before it ever becomes a rule. These moves start there.
Draw a number line from 40 to 50 and have kids place 47. Which end is it closer to? Seeing the distance makes rounding logical, not magical. Do this for a week before teaching "5 or more, round up."
Why it works: children learn more from words and pictures together than from words alone (Mayer, 2009).
Try it withRound to the Nearest Ten WorksheetWorksheetsOpen it →Model a routine for hundreds: "362 lives between 300 and 400. The halfway point is 350. 362 is past halfway, so it rounds to 400." Kids repeat the same three steps every time until it's automatic.
Why it works: handing over the work step by step, from teacher to student, is one of the most widely used teaching frameworks (Pearson and Gallagher, 1983).

Why it works: in a well-known study, a few short sessions of a simple number board game measurably boosted young children's number skills (Ramani and Siegler, 2008).

Look at the ones digit. If it's 5 or more, round up to the next ten. If it's 4 or less, round down. So 63 rounds to 60 and 65 rounds to 70.
Look at the tens digit. If it's 5 or more, round up to the next hundred. If it's 4 or less, round down. So 342 rounds to 300 and 362 rounds to 400.
Rounding helps kids estimate, which lets them check whether an answer makes sense. It's also useful for mental math and real life, like estimating a total at the store.
Start with a number line so kids see which ten or hundred a number is closer to. Then introduce the "5 or more, round up" rule once the idea makes sense.
