Fourth Grade Math Standards: What Students Should Know

What Your Fourth Grader Should Know

Geometry

In fourth grade math, your child should be able to identify and draw points, rays, angles, lines and line segments. It is also important for your student to know the difference between parallel and perpendicular lines. Your child should also be familiar with each type of triangle, as well as lines of symmetry for a variety of 2-dimensional figures.

Number and Operations

Fourth graders compare fractions that have different numerators and denominators. They also add and subtract fractions and mixed numbers with like denominators. Be sure that your fourth grader can multiply a fraction by a mixed number and solve word problems involving fractional amounts. At the fourth grade level, your child will learn to convert fractions to decimals and to compare two decimals amounts up to the hundredths place.

Measurement and Data

Your fourth grader should be able to recognize that an angle is formed by two rays that have a common endpoint. Your child must also know how to measure a variety of angles using a protractor. Fourth graders use formulas to determine the area and perimeter of a rectangle, as well as how measurement units within one system relate to one another. For example, your child will need to know that a kilogram is larger than a gram.

Operations and Algebraic Thinking

At the fourth grade level, your student will use multiplication and division to solve multi-step word problems that contain whole numbers. These word problems will require your student to use the four basic math operations and will result in a whole number answer. Lastly, be sure your fourth grader is capable of identifying the factor pairs for any whole number up to 100.

Number and Operations in Base Ten

Your fourth grade student should be able to fluently add and subtract multi-digit whole numbers. Your child will also solving more complex multiplication and division problems, such as 4532 x 3 and 2130 ÷ 2. You will also want to ensure that your fourth grader can use his or her knowledge of place value to round numbers. Finally, your child must be able to read and write multi-digit whole numbers in numerical form, word form and expanded form.
