## Reflection: Discourse and Questioning Exploring an Arithmetic Sequence - Dots - Section 1: Opening

This task is also a great opportunity for students to practice SMP 3: Construct viable arguments and critique the reasoning of the others. In the Discussion section of this lesson, students will have the opportunity to share out how they see the pattern AND how they chose to represent it.  Students can extend this work to think about how many dots there will be after 100 minutes and can use their representations to support their answers.
