Reflection: Developing a Conceptual Understanding "Kickin' Back" Retired Style - Section 2: Introduction to BINGO Add 1 or Subtract 1


This part of the today's lesson offered an opportunity for a discussion of the idea of adding one and subtracting one from a number.  I have attached four videos that demonstrate three different things. The first two are examples of students not only understanding the idea of +1 but also the ability to articulate it their peers.  The third video represents a student who is unclear of what it means to add 1 to a number and doesn't offer a rationale explanation. I have included this, because it alerted me during the introduction, that I need to touch base with her before she starts the game (I went to her group first during center time).  The fourth video is of a student explaining what it means to subtract 1 from a number.  Although he is less than enthusiastic to share, I realized that he understood it and pushed him to share his thinking.  

It is important that, in your introduction of this game, the students have a general understanding of adding and subtracting 1 from a number.  I related it to the past few days of using the number line for the Start At, Stop At activity.
