A very simple unit study for preschool through 1st grade. This would be a perfect first unit study to do with your little ones. Children are fascinated by butterflies - who isn't? If you have a 6 year old and a 4 year old or a bit younger, they could both do some parts of this. That's what I like about unit studies. There's something for everyone! The included worksheets are at first grade level, and the activities can be done by anyone 2 and up! Try this unit study and see how easy they are to do, and you can start putting together your own!
