I'm not a medical professional... IIRC, a tetanus shot is good for ten years, so if you had one four years ago, or five or six, you're still protected by it. If you needed one, I suspect nine days after the injury would be too late. If the redness persists or pus is present, it's definitely infected.
The Tiger Rising, written by the award winning author Kate DiCamillo, is an engaging story of two children whose lives are thrown together in a small town in Florida.
There are 30 chapters in The Tiger Rising which are relatively short. Within a 45 minute to one hour time frame, students should be able to read three chapters per day and answer the questions. This should allow them to finish the book within approximately 10-12 days.
