Add 3 Digit to 1 Digit Number within 1000- Grade 2 Math
Practice adding 1 digit number to a 3 digit number. This is the same as increasing the number of ones in a number and should be simple for students with a clear understanding of place value concepts. Although the 3 Digit Plus 1 Digit Addition Worksheet starts off with problems that use models for numbers, students should target being mentally proficient. Building mental fluency in such special cases of addition helps contribute towards overall proficiency in addition.
