Assessing Math Concepts: Grouping Tens

Assessing Math Concepts is a nine part series of assessments that focus on core concepts that must be in place if children are to understand and be successful in mathematics. The information that is 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 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.
