A self-teaching worktext for grade 4 math. It includes both the instruction (written directly to the student) and a variety of exercises and word problems in the same book.
This book covers many topics related to addition and subtraction: mental addition and subtraction strategies, adding and subtracting in columns, some numerical patterns, bar models in problem solving,
order of operations, line graphs and bar graphs, rounding and estimating, and money problems and discounts. Some of the lessons are even useful for 5th grade students, especially if they have not had much exposure to word problems, the order of operations, and applications of addition and subtraction.
