These are assessments created to determine if a student has mastered the skills necessary according to the Common Core State Standards.
Each standard has a separate assessment. This way you can pick and choose which standards you are assessing throughout the year depending on what grading period it is and make copies of those specific ones. Some of the assessments have to be done individually but most are done as a class to help save on assessment time.
Assessments have at least 2 problems for each standard and most have 3 or 4.
The addition/subtraction assessments have an easier (up to 5) level and the end of year mastery (up to 10) level.
Check out the preview to see EVERY page of this assessment to see if it will meet your needs. (PLEASE NOTE: the preview looks a little blurry because I first had to save it as pictures so that the file wouldn't be too big to upload into the preview. I wanted you to be able to see every page. The original is crystal clear:))
