Mathematics | Grade : 4
Domain - Number and Operations in Base Ten
Cluster - Use place value understanding and properties of operations to perform multi-digit arithmetic on whole numbers less than or equal to 1,000,000.
[4.NBT.B.4] - Fluently add and subtract multi-digit whole numbers using the standard algorithm.
- Fluency
Fluency in the grades 1–6 standards is the ability to carry out calculations and apply numerical algorithms quickly and accurately. Fluency in each grade involves a mixture of knowing some answers from memory (instant recall), knowing some answers from patterns (e.g., “adding 0 yields the same number”), and knowing some answers from the use of other strategies. The development of fluency follows a specific progression in these grades that begins with conceptual understanding and eventually requires students to “know from memory their math facts,” use various strategies to arrive at answers, and develop proficiency using the standard algorithm for each operation. (See standards 1.OA.B.3, 2.OA.B.2, 3.OA.B.5, 3.OA.C.7 and 3.NBT.A.2, 4.NBT.B.4, 5.NBT.B.5, 6.NS.B.2 and 6.NS.B.3.) - Standard algorithm
One of the conventional algorithms used in the United States based on place value and properties of operations for addition, subtraction, multiplication, and division. (See standards 4.NBT.B.4, 5.NBT.B.5, and 6.NS.B.2). - Standard Algorithms for Addition and Subtraction

[4.NBT.A.1] -
Recognize that in a multi-digit whole number, a digit in any place represents 10 times as much as it represents in the place to its right.
For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division.
