I made the number cards to go with the "houses." Each of my tables is a color and each house matched the table color. I was concerned about the numbers getting "lost" so before I laminated/cut them I took a marker and color coded the back of the number sets to go with each house (ex: the numbers for the blue house had a blue line on the back of them). You could also use color dots (like the garage sale dots) to color code as well.
I created a set of numbers that showed the 5s and 10s patterns. You can get them HERE.
I also created a simple black and white version with no patterns. You can get them HERE.
They can be used for so much more than the 100s house!
