Can the directions for questions involving pi be more specific as to when the students are to use their calculators vs. estimating pi?
In Grades 7 and 8, for constructed-response questions involving pi, students should always use the pi key. For Book 1 at Grades 7 and 8, and for all parts of the Grade 6 test, the questions will be structured to enable students to leave their answers in terms of pi. Q23: Why must the student provide evidence of three guess-and-check attempts if he or she has found the correct response on the first or second attempt (Scoring Policy #7)? Does this not contradict the fact that we accept a correct response with no work shown at all (Scoring Policy #11)? A: It is important to reinforce a systematic trial-and-error technique. The student would try reasonably closer and closer values to the correct value. After discovering the value that satisfies all of the conditions of the problem, the student would try one value immediately above and one below the correct value in order to eliminate other possibilities.
