Standards Alignment

This resource is specifically aligned to CCSS.MATH.CONTENT.1.OA.C.6. Students must add and subtract within 20, demonstrating fluency for addition and subtraction within 10. The resource also supports CCSS.MATH.CONTENT.1.OA.D.8 by requiring students to determine the unknown sum in each equation. Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

How to Use It

Use this worksheet as a seasonal math center activity during the weeks leading up to Thanksgiving. It serves as an excellent formative assessment tool; as students work, observe whether they are counting on their fingers or using mental strategies like making ten for problems such as 8+7. The expected completion time is approximately 25 minutes for the full set of 27 tasks.

Who It's For

This resource is designed for Grade 1 students working on addition fluency, though it also provides valuable review for Kindergarten students ready for a challenge. It is highly effective for Title I small groups or as a grab-and-go resource for early finishers. Pair this worksheet with an addition number line or an anchor chart showing doubles plus one strategies.

The mastery of addition within 20 is a foundational requirement for success in early elementary mathematics. According to the NAEP, students who develop early fluency with basic operations are significantly better prepared for multi-digit arithmetic and algebraic reasoning in later grades. This worksheet targets CCSS.MATH.CONTENT.1.OA.C.6 by providing 27 structured opportunities for students to add and subtract within 20. By integrating a seasonal Thanksgiving theme, the resource reduces math anxiety and increases student engagement during independent practice. Research highlighted in the ScienceDirect TpT Analysis suggests that themed, well-structured worksheets improve task persistence among young learners compared to abstract problem sets. This printable resource ensures that Grade 1 students receive the essential practice needed to achieve mathematical fluency while maintaining a high level of interest through relevant, seasonal contexts.
