Supplies: Picture(s) of parakeets, dice (I made a large one that I use for all sorts of stuff)
Activity: I started out by showing a couple pictures of parakeets (I used my sons book, but you could get them easily off the internet) and a few fun facts about them. I finished with the interesting tidbit that some parakeets can be taught to repeat what you say! I then magically poof-ed them into parakeets so they would have to repeat what I said.
A child would come up and roll the dice--what ever number they got was how many times the primary would have to repeat what I said. I would then sing a line of the song, and we would sing it as many times as was on the dice. Once they get lines, you could do this with two lines grouped together etc. Whatever your needs are.
Then entire time I was being goofy and really playing up the parakeet teacher part. Have fun with it--be silly--they'll love you for it!
Basically, that was it. . . super simple and the primary LOVED it. My sunbeam was so excited about it he insisted on wearing a green and yellow stripped polo shirt to church so he could look like a parakeet. Funny kids!
