The Identify Number- Draw Circles probe is administered class-wide, in small groups, or individually by the teacher or assessor. The teacher follows standard instructions to guide students to correctly complete a sample item then begins administration of the probe. On the left side of the page is a printed number ranging from 1-10 or 1-20 (depending on difficulty level of the probe selected) and on the right side of the page is a line. Students are required to draw the number of circles on the line that matches the number printed in the box. Students complete as many items as possible in one minute and the probe is scored as number correct per minute. Two forms of this probe are available. One contains numbers to 10 and the other contains numbers to 20. Assessors should select the one probe which most closely matches local or state instructional goals or standards.

This assessment focuses on one of the most important early numeracy skills requiring students to demonstrate concepts of number sense by using one-to-one correspondence.
