Subtracting a multiple of ten from a two-digit number is another place-value milestone. Children learn that 70 - 30 is seven tens minus three tens, not seven minus three with a zero tacked on by magic. When the number has ones, such as 64 - 20, the ones remain because only whole tens are removed. This worksheet asks for direct differences, missing ten amounts, and explanations using tens and ones. Support pages keep the tens easy and avoid close distractors. Standard and challenge pages use larger numbers and ask children to interpret a subtraction sentence in words. The work prepares children for two-digit subtraction without regrouping. Have your child say the number as tens and ones before subtracting, then check that the ones digit stayed the same when only tens were removed.
64 - 20 means 6 tens and 4 ones minus 2 tens. Four tens and 4 ones remain, so the answer is 44.
Subtracting from the ones digit even though the amount removed is only tens.
Take away tens rods and leave the ones alone.
