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 doing classroom observations, tips for organizing information, and suggestions for instruction. Black line masters are included and can be reproduced for classroom assessment activities. "Grouping Tens" helps determine if children can organize quantities into tens and ones, add and subtract tens without counting, and count groups of tens.
