Reflection: Checks for Understanding The Addition Rendition - Section 3: Center Time


As students are working with these activities, you should circulate and take note on how students combine the numbers they rolled.  I set up a piece of paper with each students name on the right side and then record the facts that they role and how they solve them.  This way I can get an idea for who each kid is solving his/her combinations.

While students are working, you will want to circulate and observe how students find combinations for each number.  Is it random or are they counting on from one number?  Are there any known facts that students have mastered?  How do students do with writing equations?  The CCSS want students to make sense of problems and persevere in solving them.  The expectation is that mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution (CCSS.Math.Practice.MP1).  In this case, the students are looking for a number to start with and then counting on from that number.
