This month, I am featuring some of my favorite websites for critical thinking and problem solving. Check back each Thursday for this special Thursday Tool School feature. Happy Surfing!
Last week, I shared an awesome resource where students are presented with a real-world math problem and are given clues and hints as they attempt to solve the problem. Read the post here. This week, I am sharing a website called “Open Middle.” The creators describe open middle problems as those that start with the same beginning, or “closed beginning,” and they end with the same answer, called a “closed end,” but there are multiple ways to approach and solve the problem, called an “open middle.” The creators consider these problems to require a higher depth of knowledge than most problems that evaluate students’ conceptual or procedural understanding of a skill. These problems also provide an excellent opportunity for some good math talk. See the example below.
