This practice has students evaluate powers in expanded and standard form, as well as writing powers from numbers. It also includes a variety of response types ranging from multiple choice to word problems. I have personally used this as my homework assignment, giving students a choice of which page to complete. There are two levels (3 and 4) which indicate the level of difficulty. Level 3 is your standard difficulty and Level 4 is more advanced, although the same content is covered.
Not only do these two assignments come with answer keys, a tutorial video is available for the Level 3 assignment. In the video I walk through every question with the required work and answers. It is a great resource for students who get stuck, can't get parent help or were absent from class. This eliminates any excuses! See the Teacher Tube link at the end of the description to access the video.
