Open Middle Math: The name “Open Middle” might sound like a strange name for a website about math problems. However, it references a very specific type of problem we try to encourage here. Most of the problems on this site have:
a “closed beginning” meaning that they all start with the same initial problem.
a “closed end” meaning that they all end with the same answer.
an “open middle” meaning that there are multiple ways to approach and ultimately solve the problem.
Open middle problems generally require a higher Depth of Knowledge than most problems that assess procedural and conceptual understanding. They support the Common Core State Standards and provide students with opportunities for discussing their thinking.
Citizen Math has a small selection of free, 2-day , real-world math problems for 6th grade through Algebra 3 / 4. Each lesson has a student and teacher guide and would be suitable for extension and enhancement of a specific math concept.
