Addition and Subtraction Fact Families Generator

To make a fact family worksheet, select values for the options shown and click the CREATE button. You can just try it with the default values, or play with the values and re-create the worksheet.

If you don't like the problems generated, hit the SCRAMBLE button and you'll get a new set of problems with the same inputs.

The options are as follows:

• Title - a short title to place at the top of the worksheet.
• sum limit - if checked and a value entered, sets the maximum sum value for the fact family. Use this to keep the problems from having large numbers.
