In this performance assessment, students will use their knowledge of adding and subtracting mixed numbers with like denominators. Students should be able to add and subtract fractions with common denominators fluently before doing this assessment. Specifically, students will be asked to complete a performance task that will check their mastery of these skills.

| Big Ideas | Competencies |
|---|---|
A. Understanding and Applying Number SystemsStudents understand that numbers hold value and can choose the appropriate representations and algorithms to reason quantitatively, abstractly, and efficiently. |
Strategies for Adding and Subtracting 1Students can add and subtract mixed numbers with like denominators, using strategies such as equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction. |
Below are analytic teacher rubrics. The column on the left shows the dimension that is being measured in the student’s performance. The levels across the top row indicate the performance level in the dimensions. Occasionally all dimensions and performance levels are exemplified by multiple students in a single recording.
