Subtraction Tuesday!!!
These should be done in groups but are designed to be done without pen and paper. I have still done a print out if you want it to make it easy for groups to discuss the problems. Recording should be allowed when explaining back to class at the end.

Teacher notes
Questions are designed to explore down through tens, use of basic facts to solve other problems, PV stratigies, and sub in parts. Look for students to make links between questions to help them solve the progressively more difficult problems.
