Reflection: Student Ownership Geometric Series Formula, Too - Section 3: Wrap it Up


I've included some examples of student notecards that cover a range of responses.  Student A gives the best description of the process they used but all of the students gave at least a partial explanation of how they found a solution.  I'm encouraged that even student C gave some idea of how they figured out the formula and believe that with more practice and encouragement they will all be writing better.  I was disappointed that none of the students really answered all three prompts, but that's something I can work with them on, especially if I use larger notecards!
