I taught K for 12 years that was the best time. Do you have any Hap Palmer records (shows my age) or cd's. I used alot of that. Google in finger plays. Most fingerplays can be made into songs or the other way. The mulberry bush is one for the days of the week. "This is the way we ( wash our clothes /anything you want) every Monday morning etc. The seasons is an oldie rock song. "Winter, Spring, Summer or Fall all you have to do is call. " I be there yes I will you have a friend"
Just brainstorming. Good luck!
