mation strategies to find a reasonable solution to this question: Ricky had 26 stickers before buying 7 from the store. Then he gave 8 to his sister. Estimate how many stickers he has left. From the choices below, select the student with the most reasonable solution. a) Student A: Ricky has around 45 stickers left. Round 26 stickers to 40, 7 bought to 10, and 8 given to 5. Add 40 + 10 to get 50. Then subtract 50 − 5 to get the estimated answer of 45.
b) Student B: Ricky has around 30 stickers left. Estimate the sum of 6 from the 26 stickers plus 7 bought to be about 20. Add the 20 to the leftover 20 to get 40. Round 8 given to 10. Then subtract 40 − 10 to get the estimated answer of 30.
c) Student C: Ricky has around 10 stickers left. Estimate the sum of 6 from the 26 stickers plus 7 bought to be about 10. Add the 10 to the leftover 10 to get 20. Round 8 given to 10. Then subtract 20 − 10 to get the estimated answer of 10.
