Mixed Addition and Subtraction Worksheets by Size and Format
Both signs on one page: open a page, press Make a new sheet, and print with the key on page 2.

More about these tools
A mixed sheet works best once each operation has been met alone. Two pages are here so far: 3-digit numbers within 1,000, with or without regrouping, and sheets where only the tens digit changes. Every sheet is built in your browser. Pick a sheet type, press Make a new sheet until the numbers suit, and print on Letter or A4. The answer key is page 2 and carries the same sheet code as the problems, so it always matches the version you handed out.
