Cross post: All the sets in Jacobs Algebra? in General Education Discussion Board Posted August 22, 2016 We're almost through Jacob's Algebra and here's what I assign: Set I is review. I always assign set I (all problems). Set II and Set III go over the same material. I assign Set III (all problems) because the answers are in the teacher's manual. Set II answers are in the back of the student book. Since my son does the work independently, I'd rather him do set III. I always assign Set IV which is the challenge exercise. Sometimes my son gets it on his own, sometimes we have to do it together. I use Set II when my son needs additional review before a test. I use the Master tests made for this series. My son really, really likes Jacobs Algebra and I'm glad we're using it. We'll finish this and move on to Mathematics: A Human Endeavor. It's even fun to talk about how things have changed since it was written. Sometimes I have to explain to my son why the comics are funny.
