#elemmathchat Chepina Rumsey, University of Northern Iowa. I love learning from students and hearing their amazing ideas!

A1: I hear an opportunity for students to explore and share their ideas. #elemmathchat

A2: I love choral counting and True/False. I use these with primary grades and my undergraduate students/future teachers! #elemmathchat

A4: Patterns in the equations, how one addend is increasing and the other is decreasing. (By either 1 or 10 in this example) #elemmathchat

A5: If one addend goes down by ten and the other addend goes up by ten, the sum is still the same. #elemmathchat

A8: Choral Counting can have lots of interesting patterns to explore! #elemmathchat

A9: Promoting Mathematical Argumentation (Rumsey & Langrall, 2016) knilt.arcc.albany.edu/images/8/88/Tc… #elemmathchat

Kindergarteners can think so deeply about ideas we often take for granted. Let's join them in what they are discovering!

In what ways have you see playfulness in your classroom? How do you cultivate wonder? Jody Guarino
