This is a set of 25 numbered (and repeated un-numbered) task cards with 25 different 2nd grade math problems, aligned to Texas TEKS 2.4A. They are similar to Common Core 2.OA.B.2 - note that Common Core is NOT mentioned or referenced in this resource. These problems switch between 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 TEKS 2.4A standard.
These task cards are labeled as TEKS 2.4A, 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.
