A self-teaching worktext for grade 2 math. It includes both the instruction (written directly to the student) and a variety of exercises and word problems in the same book.
The book deals with various addition and subtraction topics and word problems in the 2nd grade level, especially focusing on the basic addition and subtraction facts of single-digit numbers with an answer between 10 and 18. The goal is to memorize the facts, or at least become so fluent with them that an outsider cannot tell if the child remembers the answer or uses some mental math strategy to get the answer.
