This is a set of 25 numbered (and repeated un-numbered) task cards with 25 different 1st grade math problems, aligned to Common Core 1.OA.D.8 and various similar State standards. These problems require the student to determine the missing number for basic three-digit addition and subtraction problems, up to 20. An answer key, as well as a blank test sheet, are also provided.
The task cards are as follows:
#1-5 - greatest number <10
#6-20 - greatest number 5-15
#21-25 - greatest number 16-20
The task cards tend to slowly get more difficult as you go through them.
These task cards are not labeled, but aligned to Common Core 1.OA.D.8. If you would like these labeled as Common Core 1.OA.D.8 or other State standards, I have these same task cards in these formats in other listings in my shop.
