Build confidence one difference at a time
Choose subtraction within 20, 100 or 1,000 to match the numbers your learner is ready to work with. Each sheet has twenty progressively harder differences and clear space to write each answer.
Print questions or include the answers
Print the student page on its own, or show the answer key first to add a separate checking page. The matching online practice uses the same reviewed Subtraction domain and gives immediate feedback.
