Biography
Christopher Danielson has worked with math learners of all ages, from teens in his former middle school classroom to his own children, from calculus students to elementary teachers to families who visit Math-On-A-Stick, a large-scale math learning and play space at the Minnesota State Fair. Find more of his writing on his websites, talkingmathwithyourkids.com and christopherdanielson.wordpress.com.
"Danielson's book reveals the wonder and freedom of expression that many children don't often experience in mathematics. A single, simple question puts children in a position to speak mathematically, even at early ages. Ask students of all ages, 'Which one doesn't belong?' and revel in the reasoning and conversation that results."
- Dan Meyer
"Which One Doesn't Belong? is a brilliant new math book...If you are interested in inquiry-based thinking and routines that empower kids AND if you want to learn more about quality talk in the math classroom, you need this book immediately!’
- A Year of Reading, Franki Sibberson
"From kindergarten through calculus, students and their teachers gather around Which One Doesn’t Belong? to have rich, open-ended discussions about geometry."-The Mathical Prize
