## Reflection: Checks for Understanding Our Strategies for Adding Four Addends - Section 2: Introduction to New Material

Working through an entrance ticket problem (or a problem of the day) allows me to check for understanding on a skill that has already been introduced.  As we work through this problem, I am able to see (1) what strategies students are choosing and (2) what pitfalls students are falling into (i.e: what is preventing them from accurately solving the problem.  I use this information to fix any misunderstanding during my introduction to new material, guided practice, and during independent practice math groupings.
