This spreadsheet allows you to track individual mastery of all subtraction with regrouping problems going from 50-49 downwards. Only problems with positive results included, and this spreadsheet can also be used for general subtraction fluency from 50-49 downwards. Great for tracking individual student progress for academic intervention, and can also just serve as a question bank for subtraction practice.
