This is a set of 25 numbered (and repeated un-numbered) task cards with 25 different 1st grade math problems, aligned to Texas TEKS 1.3D. Note that Common Core is not mentioned or referenced in this resource. These problems require the student to add and subtract within 20, using strategies such as composing and decomposing to ten to calculate answers. An answer key, as well as a blank test sheet, are also provided, as well as two posters for the Texas standard.
