Additive Strategies for Subtraction Problems
We want to help students develop those additive strategies to think about a problem like five plus seven because then they'd be thinking more sophisticated than counting by ones. Our goal is to develop all of us into more sophisticated thinkers. So what would that look like with subtraction? Like let's just throw out a subtraction problem and see if a kid is solving that using a counting strategy. If they're thinking about five plus seven additively instead of counting by ones, give me another one,. I'm curious, five plus seven, give me one more additive strategy.
