Number System
Fluency

Students may not
achieve fluency within
the scope of one unit, but fluency is expected to be obtained by the conclusion of the course.
Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.

Fluency?
A focus on pencil-and-paper rules for decimal computation results in students' lack of attention to the actual values of the numbers.
A good place to begin decimal computation is with estimation so that students look at answers in terms of a reasonable range.
Use the distributive property to express a sum of two whole numbers 1-100 with a common factor as a multiple of a sum of two whole numbers with no common factor.
For example, the distributive property can be used to rewrite the sum 12 + 18 as 6(2 + 3).
Divide fractions using visual models and equations to represent the problem.
Skill in carrying out procedures flexibly, accurately, efficiently, and appropriately.
