Number Sense, Properties, and Operations

- Understand the structure and properties of our number system. At their most basic level numbers are abstract symbols that represent real-world quantities
The whole number system describes place value relationships and forms the foundation for efficient algorithms

Use place value and properties of operations to perform multi-digit arithmetic.
