"Decimal notation" refers to a system of writing numbers using ten different digits, which are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. In this system, each digit's position represents a value based on powers of 10. It is the most commonly used system for writing numbers in everyday life.
Full definition
Computes, in writing, the four operations with numbers that are easy to work with (including large numbers), using equivalent ways of writing numbers and the properties of operations: numbers written
in decimal notation, using rules of signs
Using models to represent fractions, students will generate equivalent fractions and
use decimal notation to express them.
Getting students to begin to understand that there are certain numbers that can't be exactly determined
in decimal notation is a difficult and important idea in developing number sense that will help them in high school, college, and beyond.
Mentally computes the four operations, especially with numbers written in
decimal notation, using equivalent ways of writing numbers and the properties of operations
Because we can write fractions with a denominator of 10 as an equivalent fraction with a denominator of 100, we can also write these numbers in
decimal notation.
