Reflection: Checks for Understanding Finding Factors and Prime Numbers - Section 3: Concept Development


For me, this is a lesson that is fun, but I find it difficulty to get in all the information I want to get in.  As you can see in my reflection video, this lesson went ok, but students still need more time with this concept. 


Logically I know that students need several lessons and multiple ways of finding factors before they are proficient.  I find myself wanting to cram things into the hour that don't need to be there, YET, like divisibility rules. (See exit ticket example)

At the end of this lesson and based off of the exit tickets, most of my students can identify prime numbers. I'm anxious to see if the vocabulary sticks and that they can relay the same information tomorrow.
