Yesterday I started the group with just POP - they will repeated anything so they all Popped too and we went faster and faster until it sounded like the last minutes of popcorn preparation. Then I introduced the quality time honored line "pop goes the weasel" (which if I remember correctly has to do with the weaving or shoemakers trade?). They liked the sound of it and no one knew what a weasel is so it was an immediate hit!
Then we made three stage puppet: color 2 circles, glue them back to back over a pencil, stick the pencil through a hole in the cup. Three steps because there are only three of us. Now push the pencil up and down to make the "weasel" pop up. We tried then on a nearby random baby and he laughed! Success.
Armed with that triumph today we make flying octopi - Octopus' Garden in the Shade?
