From our teachers' playbook

Close enough is a math skill!

What do kids learn about rounding?

Rounding means finding a nice, friendly number that's close to the real one. Kids usually start in 3rd grade, rounding to the nearest ten and hundred: 47 → 50, 362 → 400. In 4th and 5th grade they round to any place, from thousands up to millions, and to decimals. The rule is simple: look at the digit to the right, and 5 or more rounds up. The click comes when kids see why we round. It's how we estimate quickly and check if an answer makes sense.

How we teach rounding that makes sense

Rhymes help, but kids who see the number line truly understand rounding. Here's how we build both.

Which ten is closer?

Draw a number line from 40 to 50 and put 47 on it. Ask: "Which ten is it closer to?" When kids see the halfway point, the "5 or more" rule stops being magic and starts making sense.

Why it works: children learn more from words and pictures together than from words alone (Mayer, 2009).

Talk about real rounding

Ask where people round in real life: "About how many kids are in our school?" Partners argue whether you'd round to the nearest ten or hundred. Kids learn that the place you round to depends on the job.

Why it works: using clear, consistent math words out loud is one of the U.S. Department of Education's recommendations for elementary math.

Mix the places

Once kids can round to tens and hundreds separately, mix them on one page. Having to stop and find the right digit every time is what makes rounding stick.

Why it works: shuffled practice teaches kids to choose the right strategy, not just repeat one, and it improved test scores in research (Rohrer and Taylor, 2007).

Rounding questions from teachers and parents

How do you explain rounding to a child?

Rounding finds the nearest friendly number. Look at the digit to the right of the place you're rounding to. If it's 5 or more, round up. If it's 4 or less, keep the digit the same and change the rest to zeros.

What grade do kids learn rounding?

Most kids start rounding to the nearest 10 and 100 in 3rd grade. In 4th grade they round larger whole numbers to any place, and in 5th grade they round decimals.

Why does 5 round up?

It's an agreed-on rule. A number ending in 5 is exactly halfway, so mathematicians chose to round up to keep things consistent. Showing it on a number line helps kids accept it.

Why is rounding important?

Rounding helps kids estimate quickly and check their answers. If 312 + 289 comes out as 901, rounding to 300 + 300 = 600 shows something went wrong.
