This ArgoPrep worksheet will have grade-one students working on subtracting single-digit numbers from double-digit numbers, however will not require regrouping, which will be introduced in the future. Instead, students will work with numbers where the top number in the one's place is larger than that of the single-digit number. That way grade-one students won't have to borrow from the ten's place to subtract. This worksheet is a great way to prepare students for subtraction with regrouping.
