Common Core Math Standards 4.MD.7 addresses the idea of decomposing (breaking apart) an angle into smaller parts. These were created specifically for the Common Core. My district currently uses Everyday Math, and it really doesn’t cover adjacent angles.
Pages 1-3: Easy
Pages 4-6: Intermediate
Pages 7-10: Difficult (Angles with decimals)
These can be used as worksheets. These can also be projected as full color pdfs and used directly on the whiteboard for students to write on.
Let me know what you think…
I plan on making more items for the Common Core.
