What Problem Based Learning Should  Look Like In Your Classroom

By Holly Norton


Let’s start this discussion about problem solving on the right foot, this is not a discussion about word problems.   When students are given the opportunity to learn through problem solving, they are in turn given the opportunity to create, critically think, collaborate, and  communicate with each other.  Where do we start?  Read on to find out how we find the  right problem solving activities that will foster mathematical discovery, but how the teacher should guide their students through this process.


Warm Up Activities


Problem solving problems can be assigned to students at the beginning, middle, or end of a unit. Usually, if a teacher gives their students a problem to solve at the beginning of a unit, the objective is for the student to learn the content through discovery. No matter when the problem is assigned it is good practice to activate prior knowledge and give your students a warm up activity that correlates with the content of the problem.


What is a warm up? When we want students to engage and learn through problem solving, we are undoubtedly trying to access some prior knowledge in order for them to critically think. When we present a problem solving activity, we are requiring them to build on previous taught math concepts, whether that concept was taught a week ago or in a previous grade. Either in this case, a warm up activity prior to the problem solving activity would help students be a little more prepared to access skills needed in order to become most successful in engaging in the activity. 


I generally call all warm-up activities in my class a number talk.  Some would classify a number talk only as an expression students solve mentally and share their process.  I consider any warm up activity to be a “number talk”.  Here is a list of different activities that could be conducted during a warm-up activity:



These are just a few of the examples of different warm up activities that could be used.  The biggest objective of the warm-up activity is that it activates prior knowledge the students may have in order to be successful with the problem of the day.    


Below are some examples of some possible warm up activities, these are ones I have done with my class.  Some great resources is John Sangiovanni's book, Daily Routines to Jumpstart your Math Class: Elementary 3-5.
