Resources, resources, resources! Find some things that are fun and creative and go with it. This is the perfect time of year to test out some new tools! If the lesson doesn't work, that's ok, the hard part of the year is over and there's nothing to lose.
An absolutely great place to find a ton of resources in one place is Kevin Honeycutt's website. There, you can find tools and explanations on categories such as; Creating Books, Creativity, All Things Science, Odds & Ends, Video Creation and much more!
Check it out! You just might find something you can't wait to use again next year!
