This 17-lesson learning unit starts with two “Fast Action Division” exercises designed to be timed. From here, students move on to word problems that progress from one-digit, to two-digit, to three-digit divisors, and finally to worksheets comprised of a combination of addition, subtraction, multiplication, and division problems.

In all, there are more than 100 story problems included in this book. Students will get plenty of practice by the time it is completed.
