Pearson Texas Interactive Science Grade 3 Teacher's Edition & Resource

This is a spiral book on Science for grade 3 that is preowned. It is a 2015 teachers edition. I do not see many markings in the book but I did not look at each page. The cover has some damage but not bad. The cover and section a & b are raised up in the right hand bottom corner but not sure why. The book looks very good other than the information noted above.
