The purpose of this blog is to offer teaching ideas to busy math teachers. The grade levels are from middle school to high school. You are free to use the teaching ideas, problems of the week, and lesson plans. Most of the posts will concentrate on problem solving, because I believe that the best way to learn math is by doing problems.
You want to give a problem of the week for the students to do, but you don’t have time to figure out the solution before giving it to the students. You come to the right place. I search the Internet for problems of the week. I work out the solutions and get confirmation for their correctness from the authors. Then, I publish the solutions on my blog for you to use.
If you have alternative solutions, please write them in the comment box.
