These cards test a variety of place value skills (value of a number, comparing, ordering, word form, expanded form, standard form). Although they have many different uses, I find they are best when used with a generic game board in centers. My kids loving playing games and I never hear a complaint even though they are practicing test-like questions. An answer sheet is included so your students will be able to check to make sure they got the correct answer.
Hope you get as much use out of them as I have!
