Just thought I’d share a quick warm up I did with my fourth graders yesterday–nothing earth shattering, but one of those ideas that you might see and think, “Oh yeah–I haven’t done THAT in a while!”
I fairly often will do a problem and ask the students if I got the correct answer so they can cross check it with their own work. Today I asked the students to warm up by solving 3 computation problems–one addition, one subtraction, and one multiplication . . . all review. I showed all my work and made one small error in each one–an error similar to the type I see some of them doing!
