We're sure that you have a few go-to activities that you use when you have little (or a lot) of time to fill with a class.
Here are some additional fun resources we've discovered that you can add to your list!
The California State Parks created projects for teachers to do with their students. What's nice about these is that the rangers filmed videos to introduce the challenge, it's almost like your students get a mini-field trip. If you've got a way to show videos, the lessons are ready to use.
Tip: These are meant to be multi-week projects and have a lot of documentation. But you can streamline the lessons by just showing the challenge video and asking students to do an activity.
Examples:
Ever been to a restaurant with kids and gotten a box of four brand-new crayons? Wonder what happens to the slightly used crayons at the end of the meal? Crayon Collection is a nonprofit working to make sure they don't go to the landfill. They've worked with artists to create activities that you can do with just crayons and paper.
Example: Newspaper Shapes is an activity where students circle capital letters (for example, the letter A) on a sheet of newspaper, connect the dots and create a picture out of the shape it makes (like a monster).
We love Playworks, a nonprofit that helps kids stay healthy and build life skills through play (full disclosure, we share the same founder).
