Apply strategies, including place value and the properties of addition to determine the sum or difference of two whole numbers, each 999,999 or less. (b)
Determine the sum or difference of two whole numbers, each 999,999 or less, in vertical and horizontal form with or without regrouping, using paper and pencil, and using a calculator.
Demonstrate fluency with addition and subtraction within 10. (b)
Determine the sum of two whole numbers whose sum is 99 or less, using various methods. (b)
Combine parts contained in larger numbers up to 20 by using related combinations (e.g., 9 + 7 can be thought of as 9 broken up into 2 and 7; using doubles, 7 + 7 = 14; 14 + 2 = 16 or 7 broken up into 1 and 6; making a ten, 1 + 9 = 10; 10 + 6 = 16).
sums, differences, and products do not exceed five digits;
The length model (e.g., a number line) also reinforces repeated addition or skip counting. [Graphic cannot be reproduced.]
