Subtraction Strategies

I began our exploration of subtraction strategies just as I did for addition strategies. I gave all the students the same subtraction problem, and let them solve the problem however they wanted. I selected several students to write their strategies on the board. Just as with addition, the kiddos were shocked at how many different ways their friends solved the same problem! We focused on two different strategies for subtraction: Number Line (which can look three different ways) and Subtracting by Place Value.
