Math common core state standards grouped by topic for easy reference.
You cannot just look at your own grade level's standards. You also need to look at the ones below to see what they have learned.
For example, perimeter is listed as a common core standard for 3rd and 4th grade but students are responsible for knowing that topic from 3rd grade on. Percents are introduced in 6th grade for the first time.
I have included all of the standards for 5th and 6th grade and many from 4th and 3rd grouped by topic.

I am sorry that you misunderstood the intended grade levels for this product. The description says "I have included all of the standards for 6th grade and many from 5th, 4th, and 3rd grouped by topic" In the grade levels selected for this product it was marked as 5th, 6th, and 7th. At 6th grade, most of the standards from K-2 are so basic that they already know them.
Thank you for a good idea to make a separate version for the younger grades. When you look at the product you bought, on the last page, I included a link where you can search for the topics in the lower grades.
