PDF Download: Integer Addition Practice Sheet

I have many requests to create downloadable files, so, I will be publishing downloadable files in PDF starting with the Integer Addition Practice Sheet below. You are allowed to print and share the file below (and future PDF files) via hard copy or email. However, you are not allowed to sell or publish them in print or upload them on websites of any kind (e.g. blogs).

In each worksheet, I will recommend the time limit to answer the questions. This way, you should be conscious of the time since the Civil Service Exam or any other exam is usually under time pressure.

I have also placed the answer key on a different page, so you don’t have to see it when answering the practice sheet on your computer.
