3 Digit Addition and Subtraction Bundle



This 3 Digit Addition and Subtraction Bundle is a digital math activity set for three-digit addition and three-digit subtraction strategies (3-digit addition and 3-digit subtraction with regrouping). The activities come ready-made in Google Slides and Seesaw. It covers both regrouping and non-regrouping problems. The resource aligns with one of the 2nd grade Common Core Math Standards in the Numbers and Operations in Base Ten (2.NBT.7). Topics and strategies covered are base-ten blocks, expanded form, open number line, and the standard algorithm.

When you download the files, you will open two PDFs. The links to the Google Slides are available on page 5 of this PDF file. The links to Seesaw are on page 6. Please read through the instructions and guided pages to learn how to open, save, and share with your students.

  • The PDF contains a page with instructions on how to save the PowerPoint version. This would be for teachers wanting to upload pages to their own Seesaw, Canvas, or other platforms outside of Google Slides.
