Free, printable early readers...
This very simple website offers free readers to download and printout. They start out very simple, and as the child works through the stories, more and more words are added (that's how readers usually work, right?)

Scholastic Lesson Plans: a searchable, free collection of plans and projects
Looking for ideas to support a new interest, or a whole unit study? There's lots to choose from here! There are hands-on science projects, multimedia-supported lessons, book club ideas... Most are designed for classroom use, but all the lessons I've looked at are very well-suited to homeschooling.
There is the most available for elementary students, but pre-k through 12th grade are represented. Interesting to just browse if you're feeling uninspired.

The art they've chosen is stunning, and the projects tend to be managable at home, assuming you have or are willing to purchase materials when necessary. The collection includes art from a wide range of locations and time peri
BBC Primary School Languages: French, Spanish & Welsh
The BBC has fun resources to help elementary aged kids learn French, Spanish and Welsh. These are the first free resources I've found that go beyond the absolute basics (i.e. colors, numbers, and a couple phrases) while remaining fun and appropriate for younger kids.

The site is based in Australia, and uses Australian English rather than US English, but it's barely noticeable.
