How Many Hands Are In Our Room/

What are "Math Talks"?  

The Importance of Math Talks and Common Core State Standards

"Math Talk aligns with the Common Core State Standards by promoting the use of dialogue and conversation to explore mathematical thinking. Math Talk provides students an opportunity for deeper understanding through communication. Individually or in groups, students articulate and defend their ideas and analyze the reasoning of others."

The question we had during this math talk was "How many hands are in our room?"   How can we figure that out?  We discussed solutions and students agreed they wanted to trace each other's hands.  We frequently use chart paper to work in small groups, illustrating and solving our math problem of the day.
