The Time Warp Trio books are great for your students who like adventure, history, and fiction. This site is a way to introduce history in a fun way, get kids interested in the books, and excite the kids that already read them. They click on different eras of history, get a short paragraph about it plus a then and now segment. There are also fun games like this one that asks questions they need to open and read the Plentifax 487 to answer (AKA sneaky research skills). Interactive stories, poetry, and more are also featured.
Check it out and use it as a way to introduce research or the book series.
