## Reflection: Intervention and Extension Finding Factors - Section 2: Intro to New Material

Over the summer, I planned on removing this lesson from my aims sequence for this year.  I was going to jump right in to finding the greatest common factor for a set of numbers.

I had data points that suggested to me, though, that one of my classes could really benefit from having a lesson just focused on factoring numbers and divisibility rules.  I looked at the 5th End-of-Year assessment data for this group that's available to me through my school district.  I also had the summer homework that my students turned in 5 days before the start of academic classes (we have 3 days of 'orientation' to the grade where students learn routines and procedures and then a weekend).  It became very clear to me that my lower-ability math students are starting off this year quite low.  We have heterogeneous classes at my school, but one class has the students with IEPs and the students who are currently going through the RTI process (along with students of all ability levels).

I added this lesson back in for one class, so that all of my students would be better set up for success with the impending lessons on greatest common factors.  In addition to giving this class extra practice, it also means that they are currently one lesson behind my other classes.  I see this as a great thing - it gives me the opportunity to identify where students are struggling in the lessons in my other classes, and then I can proactively address those challenges with this class as I am teaching the lesson.
