Reflection: Safety Subtracting Decimals - Section 2: Practice


One of the best characteristics of great teacher is being able to think like a student.  You need to be able to anticipate student responses, potential misconceptions, budding arguments that might turn ugly, and the list goes on and on.  Although kids are most often unpredictable, we as educators can identify some of the situations that not worth the risk per say.  Avoiding potential situations is best in order to keep the peace.

In this lesson I knew if I hadn’t told the students to keep the coupons in the middle of the table there would have been many arguments over which one “belonged” to whom and "I had that first" and "she took/stole it from me".  

Deep breath.  Okay, poof, arguments gone.  Coupons go in the middle of the table and then no arguing occurs from at least this part of the day. 

Good save!
