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 16 − 7. Then solve it. ★

Skills practiced

Six story problems within 20 give your child practice with the different faces of subtraction: taking away, finding what is left, comparing two amounts (how many more), finding a missing part, and splitting a group into two kinds. First graders often think subtraction only means taking away; seeing a comparison problem and a missing-part problem on the same page widens that picture. Your child writes an equation for each one and then a short answer.

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

Common Core 1.OA.B.4: Thinking of subtraction as finding the missing part of an addition

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

Ask your child to draw each story with simple circles, crossing out what goes away. For problem 4, line up two rows of circles, one for Owen and one for Ella, and count the extra ones; this makes how many more easy to see. A common slip is adding because both numbers appear in the question. If that happens, ask: will the answer be bigger or smaller than 14?

Make it easier or harder

Easier: Start with problems 1, 2, and 3, which are all take-away stories, and act them out with small objects before writing the equation.

Harder: Have your child check each answer with an addition equation, for example 7 + 5 = 12, and write one comparison problem of their own.
