Add 10 or 100 to 3 Digit Number

- 2nd Grade Math

Practice adding 10 or 100 mentally to a 3 digit number.  Adding 10 or 100 to a number is the same as increasing the amount of tens or hundreds in a number. This should be a simple task for students comfortable in place value concepts and they should not require the use of models or pictures for help. Building mental fluency in such special cases of addition helps contribute towards overall proficiency in addition.
