Reflection: Exit Tickets Arithmetic Sequences: Growing Dots - Section 4: Closure


This lesson ran very smooth although in the 40 minute period about half of the students did not get to finish the entire investigation.  I did allow them to go back and finish the next day because I felt it was important for them to see how the three sequences appeared on the graph.  This really showed how the rate of change of the three sequences was consistent.

In the ticket out, many students said that they were still having difficulty with writing the explicit formulas for the various sequences.  I attribute this to the fact that in all of the other patterning investigations we have done, the first picture was always the first term in the sequence.  In this investigation, students also had to take the time (input) into account.  I like this aspect of the investigation because it brought the concept back around to functions (inputs and outputs).  So while some students were a little confused by the patterns not starting at 1 it made the task more rigorous and rich.
