The first time I heard the term loose parts was last fall; and trust me, you and your kids have played with loose parts. You just maybe haven’t used that term.
Loose parts play is just providing random loose parts for kids to do whatever they want with. They might make them play food or make patterns out of them. They might see how high they can stack them or sort them by color. The idea is that it is entirely up to your kid and their imagination!
This is our first real month of tot school. Prior to this, I would randomly pull an activity out. I wanted to start slow to make sure that we were both okay with it and not overwhelmed. (to be honest, she’s a pretty chill kid so she would be fine I didn’t want to bite off more than I could chew…lol) So our March Tot School is more or less just a theme for me to work with and maybe a couple of new words for her to hear.
