This is a set of 25 numbered (and repeated un-numbered) task cards with 25 different 3rd grade math problems, aligned to Common Core 3.OA.D.8 and Florida MAFS.3.OA.4.8. These problems switch between: unknown start, unknown change, unknown result, mixed and two-step, for the four operations. An answer key with both final answer and using an X for the unknown, as well as a blank test sheet, are also provided.
These task cards are labeled as Florida MAFS.3.OA.4.8, with a cover sheet and the standard on each numbered card. If you would like these labeled as Common Core or unlabeled, I have these same task cards in these formats in other listings in my shop.
See this same item labeled as Common Core 3.OA.D.8 and unlabeled:
