The kids in my algebra class have been struggling with simplifying radicals.We just had a test on it and while most kids did okay there were a few who really did poorly. I let them retake tests if they stay after school to study the material with me and then come another day to take the test. I had about eight students after school today and we were going over problems together. At one point I ran out of practice problems for simplifying radicals and I told the kids, “wait a minute while I make one up”. One kid said, “Can I make one up?”. He made one up, wrote it right on the SmartBoard, and the students all tried it. I even got to sit back and be the student for a little while. After the first student made one up all the rest of the students took turns making up problems until the late bus was called. I think they finally understand the concept.
