The Count Objects-Circle Number probe is administered class-wide, in small groups, or individually by the teacher or assessor. The assessor guides students to correctly complete a sample item and then begins probe administration. On the left side of the page students see circles that range in number from 1-10 or 1-20 (depending on probe difficulty level selected). On the right side of the page are four answer choices. Students count the circles and then select the corresponding number from the four answer choices, completing as many problems as possible in one minute. 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.
