Reflection: Intervention and Extension Addition Story Problems - Section 2: Group Interaction


Please view the picture and observe the mistakes made on this student's attempt to create her own problem.  The good news is she understood what needed to go into each area and was attempting to use her drawing strategy.  She also formed an addition sentence correctly. However, none of the information matches.  These were graded this evening and I will be going over it with her tomorrow morning.  My starting point will be her word problem she created.

She is clearly confused that her drawing strategy should represent the number of books, and then her number sentence should match.

Also, please note that this lesson was more time consuming than I had planned for.  The 30 minutes I allowed stretched into 45.  If you need to keep it under 30 I suggest you do less problems together, but you may lose your in-depth instruction by dropping some of the "meat."

Big Idea: Blending is not just for ELA teachers! Today students will learn to "blend" (combine) two sets of dots and then compare the number to another using greater than by playing versions of previous learned activities.
