This is a set of 25 numbered (and repeated un-numbered) task cards with 25 different 1st grade math problems, aligned to Florida MAFS.1.OA.4.8, 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, as well as two posters for the Florida MAFS standard.
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 labeled as Florida MAFS.1.OA.4.8, with a cover sheet and the standard on each numbered card. If you would like these labeled as Common Core, various other State standards or unlabeled, I have these same task cards in these formats in other listings in my shop.
