The investigations in this book help second graders build their understanding of the tens and ones structure of our number system.
Lessons engage children in comparing and explaining the relative size of numbers, counting larger numbers in two or more ways, and recognizing that the number of objects always remains the same despite different ways of grouping.
This book is part of the Teaching Arithmetic, Complete Series.
