## Reflection: Routines and Procedures Numerical Expressions and Patterns Introduction Lesson - Section 1: Warm Up

The warm-up is designed to get the students thinking mathematically.  Students understand that it is something to tackle, but not become frustrated with.  This is posted when they enter the class each day.

Students are asked to spend at least “3 quiet minutes” working independently and then they may choose to turn and talk to a friend about their strategies.  The conversations that students have at this time allow them to work on communicating about their mathematical thinking.
