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.

"Two Digit Addition and Subtraction" helps determine if children can use what they have learned about single digit operations to add and subtract two digit numbers competently and to establish that they can describe how to solve problems.
