Reflection: Dice Sums - Section 3: Center Time

 

While the students were engaged in combing activities, I touched base with each child in the classroom.  I wanted to find out how students were combining two numbers/set of dots.  I was looking to see which strategy that each child consistently used.  Most of the class consistently uses the counting on strategy.  I feel the modeling and explanation of this strategy over the past few lessons has helped many of the kids make the developmental jump from counting all.  Two students were exhibiting the mastery of some of the facts and would just rattle off the answer.  One student was using all three strategies at one point or another.  I will check in again with her tomorrow to see if this continues. If it does, I will point out that she is counting on and, that I would like to see her move to that strategy and away from counting all.  I will also remind her that they both work but the counting on is a much more efficient strategy.

The videos below are of two students using the counting on strategy while playing Recording Sums.

 

On another note, there were no numeral reversals by the students during the Recording Sums activity.  There are still some formation needs but the elimination of reversals was a pleasant surprise.
