What's on the worksheet

  1. Read each problem. Write the equation and the answer. Draw a picture if it helps.
  2. Write your own story problem for 8 + 6. Then solve it. ★

Skills practiced

These six story problems cover the main kinds of addition situations first graders meet: adding to a group, putting two groups together, finding a missing part, comparing two amounts (Zoe has 4 more than Sam), and adding three numbers. All sums stay within 20. Your child writes an equation for each problem and then a short answer. Learning to turn words into an equation, rather than guessing from the numbers, is the real skill here, and it carries straight into second grade math.

Common Core 1.OA.A.1: Solving story problems up to 20 that join, separate, or compare amounts

Common Core 1.OA.A.2: Solving story problems that combine three numbers with a total of 20 or less

Short descriptions in our own words. About our standards.

How to use it, step by step

  1. Your child reads the instruction out loud and explains in their own words what to do.
  2. Work through the tasks in order: the first ones are easier and warm up for the next.
  3. The task with a star is optional, for early finishers.
  4. Check together with the answer key and redo only what was wrong.

Tips for parents and teachers

Read each problem aloud and ask your child to retell it in their own words before writing anything. A quick sketch with circles or tally marks helps a lot. Watch problem 3: many children add 9 and 14 because they see two numbers. Ask: did Leo end up with 14 cars, or get 14 cars? Writing 9 + ___ = 14 shows the missing part clearly.

Make it easier or harder

Easier: Use small toys to act out each story, and let your child solve problems 1, 2, and 4 first. You can also change the numbers so every sum stays within 10.

Harder: Ask your child to solve problem 3 in two ways, by counting on and by subtracting, and to write a word problem with three numbers of their own.
