# What Math Concepts are taught in Fourth Grade?

Article Summary: Because there has been such a strong emphasis on math, fourth graders today are taught math by applying real life applications and problem solving. Fourth grade is the time when the children learn math procedures that they will carry with them throughout their lives. They are also the core for the math that they will be taught through the rest of their school years.

Because there has been such a strong emphasis on math, fourth graders today are taught math by applying real life applications and problem solving. Fourth grade is the time when the children learn math procedures that they will carry with them throughout their lives. They are also the core for the math that they will be taught through the rest of their school years. So the whole foundation of fourth grade math is built around real world processes and problem solving. Fourth grade math may focus more on how you got that answer rather than the answer itself. Yes, there are a lot of rules to remember when it comes to math, this is true, but memorizing rules is completely different from understanding why a certain process occurred.

Fourth grade introduces activities that make the children think about numbers and the relationships that surround them. This is also a time when children might form groups to collectively solve math procedures and work together. Group work seems to be very effective for getting the entire classroom active in math at the same time and to share their solutions and their thoughts. At the most basic level, children in fourth grade will learn numbers, the order of operations (PEMDAS) which is taught by most as Please Excuse My Dear Aunt Sue, it is an easy way for the children to remember the order of operations which is parenthesis, exponents, multiplication, division, addition, and subtraction. In algebraic problems, the order of operations is essential to arrive at the right solution. They then remember that they will solve first anything that is in parenthesis, next the exponents, then multiply, then divide, then add, and finally subtract. Geometry, measurements, data, and probability are also taught during fourth grade.

In fourth grade, numbers and operation will teach the children how to read and write whole numbers to the millions and understand number place value through the millions. It is important that the children understand numbers in all aspects including their systems and how to work with them in a variety of ways. A good portion of this will rely on reasoning. Very often visual models are used because that offers a much better understanding of the concepts. They will also be expected to place whole numbers, decimals or fractions in order from largest to smallest on a number line. Fourth grade expects that the children will be able to deal with larger numbers and that they are able to remember math facts quickly, especially times tables up to ten. During this year children will be able to multiply three digit numbers by two digit numbers ( 51 x 467) as well as division of dividing four digit numbers by one digit number, both with and without remainders ( 1548 ÷ 7).

Fourth graders learn to add and subtract fractions with the same denominators (meaning that the bottom numbers of the fraction will be the same). An example would be 1/4 + 2/4 = 3/4. The children will then relate these fractions to decimals and how to convert fractions into decimals at the most basic level. An example would be 0.4 is the same as 4/10. They will also add and subtract decimals, and place decimals in order from smallest to largest. The child will also round decimals to the nearest tenth, hundredth or to the nearest whole number. Fourth graders are introduced to geometry, studying points, lines, shapes and figures provide students with an understanding of the structure of space and spatial relations. The children learn that a point is a single location in space and a line is a group of points that goes on forever in both directions. They also learn how to form angles and all about rays.
