You are literally getting thousands of worksheets. I have created In-Out Function Tables for you to use as worksheets or on the board with a projector. Once you open the file, with a click of the mouse it will automatically generate a new worksheet with new numbers for you to use. It will also update the answer key to match the new worksheet that you have created. If this is a tool that you would like to use with the projector, kids can write the answers on the board. They can then click and highlight the area and the correct answer will appear.
First Tab: Single-digit Addition/Subtraction Function Tables
Second Tab: Double-digit Addition/Subtraction Function Tables
Third Tab: Triple-digit Addition/Subtraction Function Tables
**These are created using Microsoft Excel. Don’t be afraid of Excel. I have also included a short video to show you how to use this. (The video is of me using my addition function tables, but it works the same way.)
