We did a very easy review after learning a song today. After teaching the children the song, and feeling like they had it down pretty well, I needed to have a chance to repeat the song a few more times. I called up one child and had them close their eyes. Then I picked out a Skittle from my bag and showed it to the group. I then proceeded to put it in the child's mouth (note: make sure your hands are clean for this activity!) We sang the song and the child with the Skittle had until the end of the song to determine which flavor/color they had been given. If they guessed it right, they chose the next song, if they were wrong, then I chose (I picked the song we were reviewing). Simple and effective. Everyone wanted a turn!
