 * 6) Build and label a 2nd addition model for the same numbers by reversing the order they are drug to the workspace. (Example 2 yellow tiles and 4 red tiles to show 6 tiles in all.)
 * 7) Build a subtraction model for the same numbers using the largest number.
 * 8) Subtract the second largest number in the fact family by using CROSS OUT tool from the bottom toolbar to mark those that were subtracted.
 * 9) Click above the math model to label it with the subtraction sentence.

Kidspiration 3 has a Math activity template called "Fact Families". It is already installed in the computers. Click on the Math button and scroll down to see it. I would make a good follow-up/center time activity.
