Children's understanding of place value and the base-ten system is constructed upon a broad conceptual framework of number size, number relations, flexible decomposing and reconfiguring numbers, and thinking multiplicatively. To understand place value is to understand the structure and sequence of the base ten number system. As students count, they interpret the values of written and spoken numbers, and decide which number is smaller or larger, and explore the relationships among numbers; children begin to develop a picture of the number system. The base-ten numeration system is the system that most common building blocks needed to further mathematical concepts including the computation of numbers and are a basis for developing an understanding
