Question 21. a. Student gives correct answer: 98.1 = 17.93 + 18.43 + 31.4 + x b. Student gives correct answer and shows work: The sunflower grew 30.34 cm in the fourth week. c. Student gives an accurate explanation: To find the solution to this problem I gathered the
Points 0.5 0.5 1
information I was given. I knew that the sunflower’s growth was measured over four weeks, and that the total growth was 98.1 cm. The measures of the sunflower’s growth was given for the first three weeks, but not for the fourth. Since all the measurements recorded were part of the total growth, each week’s growth was added together. I set up the equation 98.1 = 17.93 +
18.43 + 31.4 + x. I added all the known measurements on the right of the equation, which equaled 67.76 cm. This number was subtracted from the total number of centimeters, 98.1, for an answer of 30.34 cm. 5.NBT.7
22. a. Student gives correct answer and shows work: Taylor earned $81.25 for babysitting on Tuesday. b. Student gives an accurate explanation: Identified strategy may vary between area model or distributive property. Explanation of efficiency will vary. 5.NBT.7
