We've been talking a lot the last few weeks about the concepts of "same" and "different." One of the main ways we've been learning about this is through playing Flower Memory Match.
I printed these flower pictures from DLTK Kids and glued them on to white construction paper squares. It would have been nice to have something sturdier but that is all I had available at the time so that is what I used.
Each time a child turns over two cards I ask - Are they the same or different? And they really picked up the concepts quickely and are having a lot of fun at the same time.
