Three math books by Fosnot and Dolk are filled with hands-on activity examples that teach math concepts. The books explain to the teacher how to engage students in conversation in which the student learns to explain their thinking and guide them to higher levels of understanding and the ability to explain what they know. Math goes beyond memorization of facts to a deeper understanding of the math concepts by using manipulation and construction of objects by students.
Books include: Constructing Number Sense, Addition, and Subtraction;
Constructing Multiplication and Division;
Constructing Fractions, Decimals, and Percents
