Practical Math Grade 4 Kwang S Ko

This is a study guide written primarily for 4th graders in order for them to learn relevant math concepts at their level. There is an introduction before each chapter that describes what will be covered. Chapter 1 deals with number sense in order for the student to learn how to add, subtract, multiply, and divide with integers. Chapter 2 teaches how to identify number sense based on the number system, algebraic expression, and order of operation. Also the student will learn about graphing functions included plotting the coordinates, making function tables, and determining the equation from the function table. Chapter 3 covers solving problems involving adding, subtracting, multiplying, and dividing decimals and fractions. Chapter 4 teaches how to identify the various angles and how to find perimeters and areas of squares, rectangles, and triangles. The student will classify triangles and parallelograms and find the volume of solids. Chapter 5 introduces frequency and frequency tables and how to identify the mean, median, and mode of data sets. Also, the student will learn about statistics, data analysis, and probability. Each concept has a step-by-step explanation on how to approach the problems. Afterwards, there is a self- test that assesses the knowledge of the student.
