3 6.EE.A.1 Student does not demonstrate understanding of exponential notation. One example would be adding four times. Student makes a common error, such as or . Student shows that , but makes an arithmetic error and arrives at an answer other than . Student shows that 4 a 6.EE.A.3 Student does not write an expression or does not indicate an understanding of . Student writes an expression relating the width () to only one part of the length ( or ). Student writes the expression incorrectly, without parentheses: , but includes each term needed to find the area. Student writes the correct expression: or b 6.EE.A.3 Student does not write an expression or does not indicate an understanding of Student writes an expression using the width, feet, but does not calculate the length, , correctly. Student writes the correct expression, Student writes the correct expression, and identifies the width, feet, and the length, feet. 5 a 6.EE.A.3 Student does not express the perimeter of the figure in terms of , using neither addition nor multiplication. Student expresses the perimeter of the figure in terms of , using either addition or multiplication, but not both. Student expresses the perimeter of the figure in terms of , using addition and multiplication but makes an error in one of the expressions. Student expresses the perimeter of the figure as: (or uses any other order of addends that is equivalent) and writes the expression b 6.EE.A.4 Student states that the expressions are not equivalent, does not use substitution, and offers no explanation. Student states that the expressions are equivalent, but student does not use substitution and offers no explanation. Student substitutes a value for in both equations, but makes one or more arithmetic mistakes and claims that the two expressions are not equivalent. Student substitutes any value for into both the addition and multiplication expression, calculates them accurately, and finds them equivalent. 6 a 6.EE.A.1 6.EE.A.2 Student evaluates both expressions incorrectly. Errors are both in order of operations and arithmetic. Student evaluates one expression correctly and one incorrectly. Errors are due to lack of application of order of operation rules. Student follows the correct order of operations on both expressions but fails to compute the exponents correctly on one or both expressions. Student evaluates both expressions accurately, applying the rules of order of operations correctly. Elena’s answer is and Jorge’s answer is .
