From our teachers' playbook

Bigger numbers, bigger sums!

What do 2nd graders learn about addition?

Second graders level up from single digits to two- and three-digit numbers. They add within 100 using place value, number lines and mental math, and learn to regroup when the ones add up to 10 or more: 38 + 25 = 63. They add 10 or 100 in their heads, add up to four two-digit numbers, and solve one- and two-step word problems. They also aim to know all their sums within 20 by memory. The click comes when kids see that regrouping is just trading 10 ones for 1 ten!

Our favorite ways to make addition stick

Second grade addition is all about place value. These moves build strong, flexible adders.

Trade ten ones for a ten

Have kids add 38 + 25 with base ten blocks. When they get 13 ones, they trade 10 for a rod. Then show the same trade on paper as the little "1" above the tens. The blocks explain the rule.

Why it works: going from real objects to pictures to symbols is a core recommendation of the U.S. Department of Education's elementary math guide.

Hop by tens and ones

Show 46 + 27 on an open number line: jump 20 to 66, then 7 more to 73. Think aloud as you hop. Kids see a way to add big numbers in their heads without any carrying at all.

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).

Sing the facts

Quick facts within 20 make everything faster. Play an adding song during transitions and have kids sing back the sums. Soon they know them without counting on fingers.

Why it works: words set to a repeating melody are easier to recall than the same words spoken (Wallace, 1994).

Questions teachers and parents ask

What addition should a 2nd grader know?

Second graders should know all sums within 20 from memory, add within 100 fluently, and add within 1,000 using place value. They also solve one- and two-step word problems.

How do you teach regrouping in 2nd grade?

Start with base ten blocks so kids can see 10 ones become 1 ten. Then connect it to writing the small 1 above the tens place. Understanding the trade makes the steps make sense.

What strategies do 2nd graders use to add?

They use number lines, breaking numbers into tens and ones, making a ten, and the standard method with regrouping. Knowing more than one way helps kids check their answers.

How can I practice addition at home?

Add prices at the store, keep score in board games or add up coins in a piggy bank. Ask your child to explain how they got their answer.
