In this performance assessment, students will demonstrate that they can add and subtract mixed numbers in a real-world situation. Specifically, students will be asked to create recipes for trail mix, given specific ingredients, amounts of those ingredients, and other requirements for each recipe. They will also be asked to justify their reasoning in how they formulated their recipes.
Students will submit their final work in their Student Booklet or may also choose to create a recipe card or other document showing their work.
This assessment might best be used after completing a unit on fractions. Students should have had instruction on equivalent fractions, as well as adding and subtracting fractions, and mixed numbers.

| 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. |
B. Operations and Algebraic ThinkingStudents can use mathematics to analyze and evaluate historical, political, economic, scientific, and social problems and make conjectures about possible solutions. |
Solve Word Problems with Whole Numbers 1Students can represent and solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. |
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.
