This is a set of 25 numbered (and repeated un-numbered) task cards with 25 different 2nd grade math problems, aligned to Common Core 2.NBT.B.9 and various similar State standards. These problems require the student to answer various problems on addition and subtraction strategies and properties of operations, mostly related to choosing between using + or - in word problems and solving simple equations. An answer key, as well as a blank test sheet, are also provided, as well as two posters for the Common Core standard.
These task cards are labeled as Common Core 2.NBT.B.9, with a cover sheet and the standard on each numbered card. If you would like these labeled as various other State standards or unlabeled, I have these same task cards in these formats in other listings in my shop.
See this item as part of a bundle for all 2nd grade Common Core 2.NBT standards:
