MISSION: ADDITION

From Leedy (2 x 2 = Boo!, 1995, etc.), a set of short math lessons in the form of comic strips: addition facts and how to write them; adding two numbers when one of the addends is greater than ten; adding columns of numbers; keeping a running total; creating addition sentences; totaling a bill when all of the addends are whole-dollar amounts. Miss Prime, a teacher of indeterminate species, presents the lessons and poses the problems; five enthusiastic pupils solve most of them, but some are left for readers, with answers on the last page. There are lots of ways to generate more addition, subtraction, or logic problems from these mini-stories, and one of them contains a lesson on sets. It's good, real-world math for home or classroom, with only one unsolved problem: Why is there a table of contents and an answer key that refer to specific pages, when the pages aren't numbered?
