About this worksheet
Twenty subtraction problems within 20, written vertically with plenty of room to write each answer. Most of them cross ten, like 12 − 7, 15 − 9 and 16 − 8, which is the hardest part of first grade subtraction.
It is a plain page with nothing to distract, the kind a teacher prints as a class set or a parent uses for ten quiet minutes after school.
Because it prints in black and white with no pictures, it is light on ink and easy to run off again whenever a child needs more practice.
