elements.
•
The student explains how to find the amount made in Year 3 (972 ×
$10 = $9,720; $9,720 × 5 = $48,600). Math work or a combination of
words and math work is acceptable to explain how the amount made.

Anchor Paper 3
Part B: Score Point 1
This response receives partial credit. It includes one of the two required
elements.
•
The student explains how to find the amount made in Year 3 [(972 ×
$10) × 5 = n; 9720 × 5 = n; 48,510 = n].
The amount made in Year 3 (48,510) is incorrect due to a computation error.
9720 × 5 is 48,600, not 48,510.
Note: If a computation error is made, credit cannot be given for computation,
but credit should be given for a valid explanation of how to solve the
problem.
