From our teachers' playbook

Five or more, raise the score!

What do 4th graders learn about rounding?

Fourth graders round big numbers to any place, from the nearest ten all the way to the nearest hundred thousand or million. They learn to find the rounding place, look at the digit to its right, and round up if it's 5 or more, or keep it if it's 4 or less. So 47,382 rounds to 47,000 to the nearest thousand. They use rounding to estimate answers and check if their work makes sense. The click comes when kids see rounding as finding the closest "friendly" number, not just following a rule.

Our favorite ways to make rounding stick

Rounding makes sense with a number line. These moves build understanding.

Show it on a number line

Draw a number line between 47,000 and 48,000 and mark 47,382. Ask, "Which is it closer to?" Seeing the halfway point makes the 5-or-more rule make sense.

Why it works: showing first, practicing together, then letting kids try alone is the "gradual release" model teachers have relied on for decades (Pearson and Gallagher, 1983).

Estimate to check

Have kids round numbers before adding, subtracting or multiplying to estimate the answer. Then they solve and compare. Mixing rounding into other math shows why it matters.

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).

Round a little every day

Start math with two or three quick rounding problems to different places. A few minutes each day keeps the skill sharp and builds speed.

Why it works: short practice spread over several days beats one long session, according to a large review of learning research (Dunlosky and colleagues, 2013).

Questions about 4th grade rounding

What place values do 4th graders round to?

Fourth graders round multi-digit numbers to any place, from tens to hundred thousands and sometimes millions.

What is the rule for rounding?

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. Then change all digits to the right to zeros.

Why do kids need to learn rounding?

Rounding helps with estimating, which is a great way to check if an answer makes sense. It's also used in everyday life, like estimating costs.

How can I practice rounding at home?

Round prices at the grocery store to estimate the total. Ask your child to round distances or populations in the news.
