Add or Subtract Ten
Worksheet · 1.NBT.B.3
Explore our collection of 2-Digit Addition and Subtraction curriculum resources for grades 1-2. This hub includes worksheets, games, readers, and activities designed to build foundational math skills through hands-on practice. Whether you're teaching first or second grade, you'll find engaging materials that support student learning.
Two-digit addition and subtraction is a critical skill that develops across the early elementary grades. In first grade, students begin by adding and subtracting multiples of ten using base-ten blocks and visual models, building an understanding of place value. By second grade, they progress to regrouping (carrying and borrowing) and solving problems within 100, often with real-world contexts like word problems and puzzles. Our resources scaffold this progression: some focus on adding or subtracting ten with visual support, while others challenge students with mixed operations and code-breaking activities.
Related concepts include place value (tens and ones), number sense, mental math strategies, and problem-solving. Students also develop fluency, accuracy, and confidence as they work through varied practice formats. The resources are teacher-authored and align with Common Core standards for grades 1 and 2, covering key skills such as fluently adding and subtracting within 100 and using strategies based on place value.
Teachers can use this hub to differentiate instruction across a mixed-ability classroom. Choose simpler worksheets for students who need extra support with base-ten concepts, and assign more challenging problems with regrouping for advanced learners. Use the printable worksheets for independent practice, homework, or assessment, and incorporate digital activities into small groups or literacy centers. The resources are also ideal for intervention, review, or as a no-prep option for substitute plans. Mix and match free and paid resources to create a customized learning path for each student.
These resources support Common Core standards for grades 1 and 2, specifically addressing addition and subtraction within 100, place value understanding, and fluency with regrouping. They are aligned to grade-level expectations for number and operations in base ten.
Yes, many of our resources are available as printable PDFs that you can download and use in your classroom. Some are free, while others require a paid Workybooks membership. You can also access digital versions for interactive practice.
Absolutely. Our resources span grades 1 and 2, with content that progresses from basic adding/subtracting tens to more complex regrouping problems. They are designed to be developmentally appropriate for each grade while challenging students appropriately.
Yes, several of our worksheets and activities include problems that require regrouping. For example, our winter-themed joke worksheet has 16 questions, some of which require regrouping. We also offer simpler resources without regrouping for initial practice.
Definitely. These resources are classroom-ready and versatile. Use them for independent practice, homework, small groups, literacy centers, or even as a quick assessment. The variety of formats makes it easy to integrate into your daily math routine.
