A set of 12 worksheets and a quiz on mental subtraction of 2-digit numbers, designed for third grade level.
Can be used in tutoring or as a resource with specific students who need more focused practice on the concept. May be used to quickly review concept or help student re-learn it. I recommend using different pages on different days so the student has to move information in and out of memory more.
I created this to use with my tutoring students; before working on this each one was heavily reliant on written methods for simple 2- and 3-digit subtraction, whereas afterwards their confidence soared as they found they could subtract numbers such as 83 - 26 and 645 - 289 mentally and quickly.
