I introduced my kindergartners to Frog and Toad today. I read them The Lost Button and during the story they had to keep track of all the attributes of the button Toad lost. I was impressed with their ability to keep five characteristics straight and their deductive capabilities. By the time we got to the interactive SMART Board vortex activity, they all just knew exactly which button was the correct one by automatically eliminating all other possibilities. After the story and interactive work, I gave each table a tray of buttons and the kids sorted them first by color and then by shape. They had to collaborate on the sorting and they did that very well. You can see the concentration on their faces and also pride in their success. (See Animoto below)
