## Reflection: Diverse Entry Points Reaction Time - Section 1: Engaging Students

I teach students in a multiage 4th and 5th grade classroom.  I am often asked, "How do you meet the needs of all your students?"  I build into the lessons a "Staircase of Complexity." Not all students are ready to learn the more complex tasks but all students are ready to be shown, or exposed to, the concept.  As I walked around the room I asked students to see if they could figure out the total length of the dropped ruler.  I’ve included an example of one student's work. This was an extension to the skills of measuring to the nearest 1/4 of an inch, the data collection and analysis of the data.
