This 283 slide PowerPoint presentation directly complements the Engage NY 4th grade Math Module 7 Topic A. Everything is ready for you to jump right in and enjoy teaching math again! I think this particular one will be especially helpful because students can see the graphics much easier on the projection board than the actual measurement tools. The material on which this PowerPoint is based can be found free of charge at www.engageny.org. I didn't create the modules, but I've made them easier for you to teach!
