Product description

From the author

This resource helps Grade 1 and early Grade 2 students practice two-digit addition without regrouping. It is a good starting point for students who are just beginning to add larger numbers.

The pack includes 50 worksheets with 20 problems on each page, giving students 1,000 problems to practice. The summer theme makes the pages look fun and bright. Each worksheet looks the same from page to page, so students always know what to expect.

Answer keys come with every worksheet, making it easy to check student work without extra effort.

This resource works in many different settings. Teachers can use it during math centers, morning work, or independent practice. It also works well as homework or for students who need extra help building their math skills.

Because every worksheet focuses on the same skill, students get a lot of repetition. This helps them build speed and confidence with two-digit addition over time.

One thing to keep in mind: this resource only covers addition without regrouping. It is meant for students who are just starting out with two-digit addition. Students who are already comfortable with regrouping will need a different resource.
