A friend of mine told me about Sunshine Math. It is a resource that can be found on the website for Saint Mark Catholic School in Florida. When you click on a grade, it opens a zip file with about 20 different math problem sets. Each problem set has 10 questions, and the questions are marked with stars. The more stars beside the question, the harder it is. The problem sets are not “pretty” – they look as if they were scanned.
I mention this site because I am always looking for good bell ringer questions. These question sets are already labelled with difficulty levels, allowing students some choice as to how much of a challenge they want to tackle. And if you really hate how they look, then you can retype them before use (as I probably will).
Have a great week.
