      Let's say you have a problem like 13-9 =4, you can tell students to start at 9 and count up to 13 using their fingers....10, 11, 12, 13, so it takes 4 counts ("4 fingers") to get to 13. Hope that makes sense!

        Hi April!

        I think it would be most helpful to see how students are solving subtraction problems and then build on what they know. Here is one way we did it:

        I think after you have that gathered, number talks are a great way to focus in on particular strategies!

        Hope that helps!
