“I hope that this Teacher’s Guide supports your own inquiry into children’s mathematics, and I hope that the images elicit brilliance from the children you do math with—wherever you and they may count.”

From the author of the award-winning Which One Doesn’t Belong? and How Many? comes How Did You Count?, the latest title in Christopher Danielson’s collection that is sure to spark conversation, questioning, and wondering amongst both younger and older students alike.

In clear, accessible language, Danielson discusses the mathematical ideas likely to emerge on each page of the How Did You Count? picture book and helps you anticipate and understand your students’ likely answers. Through classroom stories, he models listening to, talking about, and delighting in students’ ideas around counting, numbers, and operations.
