Subtract a 1-Digit Number (With Regrouping): what children learn
When the ones digit on top is smaller, we regroup: 1 ten becomes 10 ones. For 42 - 7, there are 3 tens and 12 ones, then 12 - 7 = 5, so the answer is 35.
Subtract a 1-Digit Number (With Regrouping): worked example
42 - 7 = 35
Trade 1 ten for 10 ones: 3 tens and 12 ones. 12 - 7 = 5. 3 tens and 5 ones is 35.

Subtract a 1-Digit Number (With Regrouping): how to help at home or in class
Draw the top number as sticks for tens and dots for ones. For 63 - 8, there are only 3 dots to cross out, so erase one stick and draw ten more dots, giving 13 dots. Cross out 8 and recount. Let your child do the redrawing, as the erasing is what makes the trade stick. They are ready for missing-number problems when the tens digit is lowered every time without a reminder.
