In this performance assessment, students will be asked to use addition, subtraction, multiplication, and division with multi-digit numbers that contain decimals. Specifically, students will be asked to total a shopping cart full of snacks for a slumber party. They will then need to use subtraction to figure out how much they have left to spend. When they notice a bin of bulk candy, they decide they should also buy some of that. They need to multiply to find the total cost of their bulk purchase. After leaving, they decide to take their friends shopping the night of the party, dividing equally an amount of money provided by one parent. They will need to divide to figure out how much money each person will get.
Students will need to show the processes they use to solve each problem, so the assessment needs to be administered using a printed copy of the Student Booklet.
This assessment would best be used after instruction on all four arithmetic algorithms to solve multi-digit decimal problems.

| 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. |
Fluently Divide 2Students can fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. |
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.
