7 a A-APR.1 Student’s work is blank or demonstrates no understanding of multiplication of polynomials. Student made more than one error in his multiplication but demonstrates some understanding of multiplication of polynomials. Student made a minor error in the multiplication. Student multiplied correctly and expressed the resulting polynomial as a sum of monomials. b A-APR.1 Student’s explanation is missing or did not demonstrate a level of thinking that was higher than what was given in the problem’s description of Ahmed’s thinking. Student used language that did not indicate an understanding of base x and/or the place value system. Student may have used language such as shifting or moving. Student made only minor errors in the use of mathematically correct language to relate the new number to the old in terms of place value and/or the use of base . Student made no errors in the use of mathematically correct language to relate the new number to the old in terms of place value and/or the use of base . 8 a–c A-APR.1 Student showed limited or no understanding of polynomial multiplication and of evaluating a polynomial for the given value of . Student made multiple errors but showed some understanding of polynomial multiplication. Student may not have combined like terms to present the product as the sum of monomials. Student made one or two minor errors but demonstrated knowledge of polynomial multiplication and combining like terms to create the new polynomial. Student also showed understanding of evaluating a polynomial for the given value of . Student completed all products correctly, expressing each as a sum of monomials with like terms collected, and evaluated correctly when x is 10.
