The Ranger in Time puzzle goes with the book Ranger in Time: Rescue on the Oregon Trail by Kate Messner. This is a great book for students in 2nd through 5th grades. It teaches students about pioneers as Ranger, a Golden Retriever, travels back in time. The puzzle can be used with social studies, reading, or to learn more vocabulary. Since the puzzle may be more difficult for younger students, I have included a copy with some of the letters added to the puzzle to make it easier for struggling students. I hope your students enjoy this puzzle!
