Common Core Math – Details

Problem-Attic now has more than 25,000 questions aligned to Common Core State Standards for Mathematics. Roughly 25% are free-response, multi-step or open-ended questions and tasks. See below for design highlights, or check out these sample documents.

The questions cover grades 1–8 and high school. Here’s the breakdown:

Grade or
HS Subject

Grade 1 566
Grade 2 1170
Grade 3 1782
Grade 4 2572
Grade 5 1718
Grade 6 2556

TOTAL 25420

The overall average is nearly 2000 questions per grade or subject and 60 per standard. For a complete list of CCSS math standards and the number of questions for each, please see this pdf document.

The Common Core Math database is available by subscription. All questions are original. There is no overlap with NY Regents Exams or other states' released tests in Problem-Attic. To help you evaluate the content before you subscribe, we’ve posted many sample documents and made a large number of questions available for use in the Play Area.

Design Highlights
  • All questions in the Common Core math database are hand-written by highly qualified teachers and curriculum specialists. (They are not algorithm-generated.) In addition, they are carefully aligned, edited and reviewed by EducAide Software, which has 20 years of experience developing questions for state standards.
  • The database is intended for both instruction and assessment. Alignment to the standards is as tight as possible while still allowing some flexibility for teaching, not just testing. While most questions will function very well for measuring student progress, in accordance with the standards, some questions are included for challenge, extra credit, and extending ideas.
  • Questions are aligned to only one standard. There is no duplication. For questions that can conceivably go with multiple standards, we went for the best fit. We also tried to keep similar questions together, so that it’s not necessary to jump through multiple standards to find variations.
  • All questions are paired for easy pre- and post-testing, makeup tests, etc. You will not notice this on the sample documents, but if you visit the Play Area, it will be apparent that two questions in-a-row are always similar. This provides a nice balance between repetition and variety and also helps with test security, as the two questions, which are close in difficulty and style, can be assigned to different students and graded the same way.
  • The questions are rich with graphics and interesting scenarios, including a lot of real-world data. With the editor, you can use these graphics and scenarios as the basis for new questions. The process is facilitated with a button in the editor labeled “Duplicate”. Also, Problem-Attic is smart enough not to repeat certain figures or text which is marked as an “intro”, if it appears in successive questions.

Please note:

  • The CCSS Math database was originally divided into two groups, multiple-choice and free-response. Now all questions are merged into a single database. Problem-Attic has Add and Filter buttons that greatly speed up selection, even with such a large database. Also, there’s an option to hide choices, which can effectively convert about 60% of the multiple-choice questions into free-response. This makes the database useful for all kinds of classroom activities, not just assessment.
  • When viewing problems for a particular standard, you’ll see up to 100 per page. Often there will be more. Be sure to scroll to the buttom of the page and click Next, to view them all. The questions are organized generally by level of difficulty and, by default, the easiest come first. Problem-Attic lets you reverse the order. You can try this in the Play Area. Press the Sort button to put the most rigorous questions, usually open-ended or multi-step, at the top.
