From our teachers' playbook

Big numbers, clean columns, no fear

What do 4th graders learn about addition?

Fourth graders add whole numbers up to one million using the standard method: line up the places, add from right to left and regroup when a place goes over 9. For example, 45,678 + 23,456 = 69,134. They solve multi-step word problems and check their answers by estimating first. Fourth grade also brings adding fractions with the same denominator: 2/8 + 3/8 = 5/8. The click moment is when a child sees that regrouping works the same in the thousands place as it does in the ones.

Our favorite ways to teach 4th grade addition

Big-number addition is about place value and careful habits. These moves build both.

Regroup out loud

Model a big problem on grid paper, one digit per box. Say each step: "8 plus 6 is 14. Write 4, regroup 1 ten." Lining up digits in boxes prevents the most common mistakes.

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).

Fraction pieces

For adding fractions, kids use fraction strips: two eighths plus three eighths makes five eighths. Seeing that the pieces stay the same size shows why the denominator doesn't change.

Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.

Questions teachers and parents ask about 4th grade addition

What addition do 4th graders learn?

They fluently add multi-digit whole numbers up to one million with the standard method and add fractions and mixed numbers with like denominators.

Why does my child make mistakes adding big numbers?

Usually the digits aren't lined up or a regrouped number was forgotten. Grid paper and estimating first help catch both errors.

How do you add fractions with the same denominator?

Add the numerators and keep the denominator the same. 3/10 + 4/10 = 7/10, because you're adding tenths to tenths.

How can I help my child check their addition?

Estimate before solving and compare. Or check by subtracting: if 1,250 + 750 = 2,000, then 2,000 − 750 should equal 1,250.
