Grade 1 Addition and Subtraction Story Worksheets

These six printable Grade 1 math-story worksheets turn addition and subtraction within 20 into short situations children can picture and discuss. Each two-page PDF includes 10 illustrated word problems, answer space, and a matching answer key—60 problems across the complete review set.

About this worksheet set

These worksheet PDFs are created by CheeryPages for printable classroom, homeschool, and early learning practice. Layouts are checked for readable spacing, clear instructions, and standard paper printing before publishing.

Learning goals

What learners practise

  • Identify whether a story describes joining or separating quantities.
  • Represent a problem with objects, drawings, or an equation.
  • Add and subtract accurately with answers within 20.
  • Explain why the chosen operation matches the situation.
  • Check whether an answer is reasonable in the original story.
  • Write a complete answer that includes the correct unit or object.

What makes a math story different from a number sentence?

A number sentence tells the operation directly. A math story asks the learner to make sense of a situation first: Is a quantity growing, shrinking, or being compared? Children should identify what is known, what is changing, and what the question asks before calculating. That meaning-making step is the central skill in this collection.

A reliable way to solve each problem

Read the story once for meaning. Read it again and underline the quantities. Retell the situation using counters, a quick drawing, or a number line. Choose addition when quantities are joined and subtraction when part is removed or a difference is found. Calculate, then reread the question and write an answer that names the unit.

Why keyword tricks are not enough

Words such as “altogether” and “left” can be useful clues, but children need to understand the event rather than hunt for one magic word. Ask, “What happened to the amount?” A learner who can explain the action is more likely to choose the correct operation when familiar keywords are absent.

Using drawings without creating dependence

Pictures and counters are valid mathematical tools. Over time, encourage learners to move from detailed drawings to efficient marks, tens frames, or jumps on a number line. The goal is not to remove representations quickly; it is to help the learner select a representation that makes the relationship clear.

A simple teaching sequence

Step 1

Retell the event

Before calculating, ask the learner to explain what happened without repeating the exact sentence.

Step 2

Model the quantities

Use counters, a quick sketch, or a number line to show the starting amount and the change.

Step 3

Write and solve

Record an addition or subtraction equation, solve it, and compare the result with the model.

Step 4

Answer the question

Finish with a short sentence that names what the number represents, not only a bare numeral.

How to adjust the challenge

More support

Read one problem aloud, limit the page to four selected cards, and provide counters or a number line. Let the learner explain orally while an adult records the equation.

Expected practice

Complete all 10 problems using a chosen representation and write a number sentence or complete answer for each.

Extra challenge

Ask the learner to write a related inverse equation, create a new story for the same numbers, or change one detail so the operation changes.

Quick assessment checklist

  • The learner identifies the action in the story before calculating.
  • The chosen operation matches the situation.
  • The representation and equation describe the same quantities.
  • The calculation is accurate and stays within the intended number range.
  • The final response answers the question and names what was counted.

Standards and curriculum note

The problem types and number range are designed to support CCSS.Math.Content.1.OA.A.1, which addresses addition and subtraction word problems within 20. This is an editorial alignment reference, not certification or endorsement. Local pacing and required problem structures may differ.

Home and Classroom Use

  • Solve one card together and compare two different representations for the same story.
  • Ask partners to sort selected problems into “joining” and “separating” groups before solving.
  • Use an unfinished problem as an exit ticket: operation, equation, answer, and one sentence of reasoning.
  • Invite learners to act out a story with classroom objects before drawing it.

Printing Tips

  • Print on US Letter paper at 100% or Actual Size so clocks, writing lines, and picture boxes keep their intended proportions.
  • Print page one for the learner and keep page two as the matching adult answer key.
  • Choose grayscale when color is unavailable; instructions never depend on color alone.
  • For repeated practice, place the student page in a dry-erase sleeve and use a fine-tip marker.

Frequently Asked Questions

What number range do these Grade 1 problems use?

Every addition and subtraction story has a whole-number answer within 20.

How many word problems are included?

There are 10 problems per worksheet and six worksheets, for 60 practice problems in the complete collection.

Do children need to write an equation?

The page provides answer space rather than requiring one fixed method. Teachers may ask for an equation, drawing, number-line model, or complete sentence depending on the learner’s goal.

Can a child use counters?

Yes. Objects, drawings, and equations are all useful Grade 1 representations. The adult can gradually encourage more efficient models as understanding becomes secure.

Are matching answer keys included?

Yes. The second page of every PDF gives the numerical answer to each same-numbered problem.

Is this official Common Core material?

No. The task design references a relevant Common Core domain, but CheeryPages is independent and the worksheets are not officially endorsed.

How this collection was made

Created by
CheeryPages Editorial Team
Method
The questions and matching answer keys are generated deterministically, then placed into a branded print layout with original CheeryPages illustration assets. AI-assisted illustration and drafting are disclosed in the site policy.
Purpose
To give families and educators reusable practice that is easier to explain, print, and check than a pile of unrelated activity pages.
Review status
Draft. Technical generation and layout checks are complete; educator accuracy, accessibility, and classroom-use review are still required before publication.
