Instructional Strategies for Mathematics

Cognitive Demand 

Cognitive demand represents the type of thinking, or the level/depth of complexity of thought expected.

Depth of Knowledge

Ohio Developed Depth of Knowledge Materials 

These Ohio developed materials provide Depth of Knowledge examples at different grade levels. Districts can use these materials to better understand Depth of Knowledge and create their own classroom problems to use during instruction.

Other Depth of Knowledge Resources

Depth of knowledge sample problems by grade level

Previously, Iowa's Area Education Agency (AEA) 267 put together standards-based assessment questions using Webb’s Depth of Knowledge (DOK) levels across the standards using resources like Illustrative Mathematics and the National Assessment for Educational Progress (NAEP). The purpose of their documents was to help educators gauge the quality of their curriculum, instruction and assessments within and across grades, and plan instruction. The standards-based assessment questions, within and across grades, were provided across the assigned Webb’s Depth of Knowledge (DOK) levels of the standards. These quality assessment items can be used to help bring more clarity to what it is that students are expected to learn within and across the standards and their assigned DOK level  The sample items are not intended to be used as practice tests. While these documents are no longer available by the AEA 267, they are available by the Department upon request.  To request the AEA 267 DOK documents, email the Office of Learning and Instructional Strategies (
