Visitors to Noelle Clark's third grade classroom were understandably excited to hear a student's mathematical thinking during a game of "Anything But Five," in Unit 2: Session 24. The addends the students spun in the game were 6 + 8 + 9 + 6. The student said, "I know there are fives in all those numbers. I added 5, 5, 5, 5 to make 20. Then I added what was left. 1, 3, 4, 1 to make 9. 20 + 9 = 29."
