These subtraction puzzles are designed to see who really understands the column method for subtraction!
There are 8 different puzzles where students have to work out the missing digits to make the sums true. This requires them to think deeply about how to borrow across columns in order to make all the digits in the sum correct.
Would work well as an extension for students who are already quite confident with subtraction.
