5.2 Unit 1: Order of Operations
- Solve problems by representing mathematical relationships between quantities
using mathematical expressions and equations. - Use the four whole number operations efficiently, including the application
of order of operations. - Write and evaluate mathematical expressions with and without using symbols.
- Apply strategies for multiplying a 2- or 3-digit number by a 2-digit number.
- Develop paper-and-pencil multiplication algorithms (not limited to the
traditional algorithm) for 3- or 4-digit number multiplied by a 2- or 3-digit
number. - Apply paper-and-pencil algorithms for division.
- Solve problems involving multiplication and division.
- Investigate the effects of the powers of 10 on a whole number.
- Understand multiplying whole number by a power of ten (523 x 105 = 523 x (10
x 10 x 10 x 10 x 10) = 523 x 100,000 = 52,300,000).
