Add 3 Digit with 3 Digit Number

- 3rd Grade Math

By the end of the third grade, students should be fluent with addition within 1000. Students already had considerable practice of addition within 1000 in the second grade. But as fluency is an expectation in third grade, students must be exposed to a variety of methods, including the standard algorithm for addition. In 3 Digit + 3 Digit Addition Worksheet, students add 3 digit numbers to other 3 digit numbers without any regrouping.
