I'm helping tutor a 4th grader in math through the Math Buddy program where I work. They provide every 4th grader in one of our local elementary schools with a Math Buddy to tutor them throughout the year.
My buddy is doing great at addition and the other things his teacher assigns, but he is completely balking at doing subtraction. I'm not quite sure how to help him out, but was looking for some ideas on different ways to try and explain subtraction to him. I know his grade testing is coming up in March and I was hoping he'd understand it better by then so he doesn't get so frustrated on his test.
Props, scratch paper, and counting on fingers is okay for now. Got any ideas?
