I’ve been working on my Wakelet collections so that I’ll eventually have one for every month. To be consistent, I split my Halloween/October collection into two different collections. So, there is now a Halloween one and an October one (which contains a link to the Halloween one as well.)
Some upcoming October holidays/celebrations that you can really have fun with in the classroom are Powers of 10 Day (10/10 of course!) and Global Maker Day on 10/18. I’m still adding resources as they show up on social media, so keep on the lookout for more ideas for those.
In the meantime, the Halloween Wakelet is loaded with lots of math, literature, and science ideas. Many of them can be modified easily to use for a fall theme if you are in a school where Halloween lessons are discouraged. There are free digital breakouts in the collection, a slow reveal graph about candy sales, and tons of puzzles. One of my favorite lessons that I used to do with my primary students was Monster Box, and you will find an updated link to that with a free link to a Google Slides presentation from SlidesMania with cute monsters. It uses the Visible Thinking Routine, “Step Inside,” and I am sure you can find other ways to adapt it.
Of course, don’t forget that September still has a few more fun days left, including International Podcasting Day. If you want to get a head start on October and celebrate International Podcasting Day at the same time, here is a wonderful list from @GladeJeff of Halloween Podcasts for grades PK-12.
