4. 2 Digit - 1 Digit with Regrouping
Subtract a 1 digit number from a 2 digit number with regrouping. 2 Digit Minus 1 Digit Subtraction with Regrouping Worksheet involves situations, where it is necessary to decompose the tens as ones to subtract. For example, to subtract 9 from 26, it is important to visualize 26 as 1 ten and 16 ones, so that we can subtract 9 ones. Once this skill is developed, it is simple to subtract using previous knowledge of subtracting ones and tens separately. To cultivate deeper understanding, it is paramount that students subtract based on these place value skills,
before moving on to the standard algorithm.
