Problem C1

 a. Ms. Sabanosh encouraged students to make inferences and predictions by asking them to think about how many raisins would be in one of the unopened boxes. b. When the students discussed what would not be good guesses about the number of raisins in a box, they clearly suggested numbers that were not likely.

 Problem C2 Answers will vary. One example of a question is, "If I went to the store and bought a different brand of raisins, but the same size box, how many raisins do you think would be in that box?"

 Problem C3 Two conjectures that might result are, "A small [half-ounce] box of raisins cannot contain 100 raisins" and "A small box of raisins will contain between 14 and 35 raisins." These could be formulated as the following question to be investigated: "What is the smallest and largest number of raisins that a box can hold?" The students could investigate this question by obtaining additional half-ounce boxes of raisins of the same brand, then counting the number of raisins in each box, and finally adding this information to their line plot. An extension would then be to count and analyze the number of raisins in half-ounce boxes of other brand names.
