Reflection: Developing a Conceptual Understanding Estimating Sums and Differences of Whole Numbers - Section 5: Closure

 

Using number lines is something that I don't do a lot.  However, after this lesson, I will incorporate them more into my lessons.  It really gives the students a visual of rounding.  Sometimes when we teach the rules of rounding some of the students do not have a clue about what we're talking about.  They can go through the steps, but it doesn't mean anything to them.  When they put it on a number line, they can see it.  This gives conceptual understanding of actually what rounding means.
