Here are a few other color matching games that you can make from things you may have lying around the house, things you can get for free, or products you could purchase for a dollar or less.
This first game is nothing more than popsicle sticks and little girl hair clips. The hair clips provide great practice for the "pinching" skill.
This is simply a set of pencil erasers and colored straws (and white straws with colored lines). If you wanted you could even have double the number of erasers and an eraser could be placed on each end of the straw. That's up to you.
Finally, we have the pretty popular paint sample and paper clip activity. I'm sure there are a ton of variations you can do with this one as well.
