The response achieves the following: The response demonstrates limited to no understanding of decomposing a sum of fractions. Response is incorrect. 0 Response shows no application of a strategy. Mathematical ideas cannot be interpreted or lack sufficient evidence to support even a limited understanding. Exemplar Response Points Sample Response Awarded Kate’s equation is correct. All the fractions have the same denominator, so you just have to add the numerators to get the sum. Kate added numerators 2, 1, and 1, so the 2 numerator in her fraction is 4. OR other valid explanation Kate’s equation is correct. 1 OR provides an invalid explanation. 0 Response is irrelevant, inappropriate, or not provided. Item 17 Points Description
