One copy for every student: type the first names and get one PDF, with each name on that student's own pages. Every student's pages use the same settings.

Class lists are used only to draw the pages and are never saved.

Every student gets the same problems (the same Sheet number), so one answer key checks them all.

Questions and answers

Which numbers are on a 3-digit addition sheet?

Both numbers are three-digit, 100 to 999.

What does regrouping mean in 3-digit addition?

A problem regroups when a column has to carry: the ones or the tens add up to 10 or more. With makes every problem do it; Without makes none do.

How many problems can a 3-digit addition sheet have?

Choose 20, 30, 50 or 100. All the problems print on one page; with Answer key ticked, the answers are page 2.

Is there an answer key for the 3-digit addition sheet?

Yes. Tick Answer key and page 2 of the PDF lists every answer in the same order as the problems.

How do I print a different 3-digit addition sheet?

Change the sheet number. Each number prints its own problems, and the same number always prints the same sheet.
