This is another wonderful series I grew up reading. Mary P Osborne did a wonderful job. All of these books are reference something historical, so with every book, you are learning a piece of history. Like Junie B Jones, they are perfect for children who want to begin reading chapter books. They are fairly short but are packed with a lot of information. Students could easily do many types of history projects with these books. I could see students anywhere from 2nd and above reading these books. They are absolutely wonderful and I definitely recommend having multiple MTH books in your classroom.
