This is a set of 25 numbered (and repeated un-numbered) task cards with 25 different 2nd grade math problems, aligned to Oklahoma 2.N.2.2. They are similar to Common Core 2.OA.B.2 - note that Common Core is NOT mentioned or referenced in this resource. However, these task cards are more broad than the Common Core standard, to present addition and subtraction in various ways to demonstrate overall fluency with basic addition and subtraction within 20. An answer key, as well as a blank test sheet, are also provided, as well as two posters for the Oklahoma 2.N.2.2 standard.
The 25 task cards are as follows:
#1-5 - addition/subtraction <=10
#6-10 - addition/subtraction 11-20
#11-15 - addition of 3 numbers
#16-20 - True/False for basic equations <=20
#21-25 - Word Problems (add 2 or 3 numbers, or subtract 2 numbers)
These task cards are labeled as 2.N.2.2, with two cover sheets (one with the standard number, and one with the standard number and a brief description) and the standard on each numbered card.
