CCSS.MATH.CONTENT.1.OA.A.1— Use addition and subtraction within 20 to solve word problems.- Skill Focus: Addition & Subtraction Word Problems
- Format: 5 pages · 18 problems · Answer key included · PDF
- Best For: Independent practice, formative assessment, homework
- Time: 20–30 minutes
What's Inside
This five-page PDF resource has 18 unique word problems for first graders. The worksheet is organized into four sections: addition, subtraction, mixed practice, and a challenge corner. A complete answer key is provided for quick grading, making it easy for teachers or parents to check work.
Skill Progression
The worksheet uses a gradual release model to build independence.
- Guided Practice: The first section focuses on addition, letting students build momentum with one operation.
- Supported Practice: The next sections add subtraction and then mixed problems, requiring students to analyze each problem to determine the operation.
- Independent Practice: The final "Challenge Corner" features more complex problems, encouraging students to apply their skills with greater autonomy.
Standards Alignment
This worksheet is aligned with Common Core standard CCSS.MATH.CONTENT.1.OA.A.1, which requires students to use addition and subtraction within 20 to solve word problems. It also supports skills for CCSS.MATH.CONTENT.1.OA.D.8. Both standard codes can be copied directly into lesson plans or curriculum mapping tools.
How to Use It
Use this resource after a direct instruction lesson for independent practice, a math center rotation, or as a focused homework assignment. For a formative assessment, observe who correctly identifies the operation in the mixed practice section to find students needing support. Most students will finish in 20-30 minutes.
Who It's For
This resource is for first graders developing their ability to solve basic word problems. It can be used for whole-class practice, small groups, or for advanced kindergarteners. To support readers, pair this with an anchor chart of key math vocabulary.
This worksheet addresses the foundational skill of problem-solving in CCSS.MATH.CONTENT.1.OA.A.1, a critical predictor of future mathematics achievement. Translating a scenario into an equation is key to algebraic thinking. Research highlighted in the RAND AIRS (2024) report emphasizes early, consistent exposure to problem-solving to build procedural fluency and conceptual understanding. The structured progression from single-operation problems to mixed challenges supports cognitive flexibility. By providing students with 18 opportunities to practice, this worksheet helps them move beyond simple calculation to engage with the application of mathematics, a practice Fisher & Frey (2014) identify as essential for creating independent learners.
