B5-The students used imaginary tiles but used 100 instead of 5 cubed (125). I would have the students write down 625, 125, 25, 5, 1...as they solve the problem B6-The students started with 25 instead of goes to highest power of 5 (125) to start taking away from 342.

Finding the equivalent of a different base develops students' sense of numbers and operations by making them apply rules that they take for granted. Allows the use of mental math as well!
