Assessing Math Concepts is a nine-part series of assessments focusing on core concepts that must be in place if children are to understand and succeed in mathematics. The information gathered and organized helps the teacher’s awareness of the important steps in the learning process and provides information for instructional decision-making. Each book provides the teacher with background information for giving and using the assessment tasks, instructions for making classroom observations, tips for organizing information, and suggestions for instruction. Black line masters are included and can be reproduced for classroom assessment activities. "Changing Numbers" will assess if children can: change one quantity to another, describe how one number is related to another, know how many to take away or add, determine whether to take away or add to reach another number and count on or remove extras to change a number.
