From our teachers' playbook

Put together, take apart

What do 1st graders learn about basic operations?

First graders focus on addition and subtraction within 20. They learn that adding means putting groups together and subtracting means taking away or finding the difference. They practice strategies like counting on, making ten and using doubles: 7 + 8 = 7 + 7 + 1 = 15. They also solve word problems and learn that addition and subtraction are related: if 6 + 4 = 10, then 10 − 4 = 6. The click moment is when kids solve a fact with a strategy instead of counting fingers.

Our favorite ways to teach basic operations

First graders learn operations best through stories, objects and lots of talk.

Act out word problems

Read a word problem and have kids act it out with counters or even themselves: "Four kids are on the rug. Two more join." Then they solve the barnyard math problems the same way. Acting it out shows whether to add or subtract.

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.

How did you solve it?

After each problem, ask two kids to share different strategies. One counted on, one made ten. Hearing classmates' thinking grows everyone's toolbox.

Why it works: when kids say the precise math words, their understanding gets sharper, a recommendation of the U.S. Department of Education's elementary math guide.

Daily word problem

Start each math lesson with one word problem from the practice worksheet. A little every day builds confidence and keeps addition and subtraction fresh.

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 teachers and parents ask about basic operations

What math operations do 1st graders learn?

First graders learn addition and subtraction, mostly within 20. They also start adding within 100 using tens and ones.

What strategies help with addition facts?

Counting on, making ten, doubles and doubles plus one are the big ones. They help kids solve facts quickly without counting every object.

How do I know if a word problem is adding or subtracting?

Ask whether groups are joining together (add) or something is being taken away or compared (subtract). Acting it out with objects makes it clear.

How can I practice math facts at home?

Play dice and card games, count snacks, or make up quick story problems at dinner. Five minutes of fun practice a day helps a lot.
