From our teachers' playbook

Decimals, fractions and really big numbers.

What do 5th graders learn about addition?

By 5th grade, kids know how to add whole numbers, so the challenge moves to decimals and fractions. They add decimals to the thousandths by lining up the decimal points, like 3.45 + 0.678 = 4.128. They add fractions with unlike denominators by finding equivalent fractions first: 1/3 + 1/4 = 4/12 + 3/12 = 7/12. They also add mixed numbers and solve multi-step word problems that combine addition with other operations. The click moment is when kids see that both skills follow one rule: you can only add parts that are the same size.

Our favorite ways to teach 5th grade addition

Most mistakes here are about lining things up, digits or fraction parts. These moves make the "same size" rule visible.

Draw the fraction bars

Before adding 1/2 + 1/3, have kids draw both as bars of the same length. They will see the pieces are different sizes and can't be counted together. Cutting both bars into sixths shows why we need a common denominator.

Why it works: pairing a picture with each word gives kids two ways to remember it, a well-tested principle of how people learn (Mayer, 2009).

Model the common denominator

Work one problem aloud: "I need pieces the same size. What number can both 4 and 6 go into? 12!" Rename each fraction, add, then simplify. Have kids talk through the next problem with a partner using the same words.

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).

Mix them up

Once kids can add decimals and fractions, put both on the same page with a few whole-number problems too. Kids have to stop and decide: line up decimal points, or find a common denominator? That decision is where the real learning happens.

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).

Questions parents and teachers ask us

What kind of addition do 5th graders do?

Fifth graders add decimals to the thousandths, fractions and mixed numbers with unlike denominators, and large whole numbers in multi-step word problems.

How do you add fractions with different denominators?

Find a common denominator, rewrite each fraction with it, then add the numerators. For 1/2 + 1/3, use sixths: 3/6 + 2/6 = 5/6.

Why does my child get decimal addition wrong?

Usually the digits are lined up on the right instead of at the decimal point. Have them line up the decimal points and add zeros as placeholders, so 2.5 + 1.25 becomes 2.50 + 1.25.

How do I add mixed numbers?

Add the whole numbers, then add the fractions using a common denominator. If the fraction part is more than one whole, regroup it into the whole number.
