Big Idea: When finding the difference, it is sometimes more effective to add than to subtract. Students can visualize the difference between two numbers by counting up by 10s or 100s in order to build fluency. Finding the difference between numbers can be simplified when students see that they need to count up to arrive at the greater number.
