Fourth Grade Math

Fourth grade math problems are more complex than third, children should be adding estimation, probability, and fractions on top of the foundation of arithmetic skills. However, there is much review to ensure the basic understandings and mechanics remain solid. The 4th grade math tests are more demanding.

Fourth grade math curriculum should be taught using 4th grade math worksheets and 4th grade math games. A fourth grade math curriculum should rely on many learning tools – fourth grade lessons with activities, worksheets, reinforcement exercises, and assessments.

This guide to a fourth grade math curriculum is a reference tool for Time4Learning parents. Time4Learning is an online learning system for homeschool education, enrichment, tutoring, or for sharpening summer skills.

Fourth Grade Math – What are the Standards and Curriculum?

A fourth grade math curriculum should cover all the math strands, not just arithmetic. The major math strands for fourth grade curriculum are number sense and operations, algebra, geometry and spatial sense, measurement, and data analysis and probability.

Fourth grade math students build on what they learned in kindergarten, first grade and second grade math, which led them to the number 1000. In fourth grade math they work with numbers through the hundred-thousands or more. They learn about decimals in the context of money and get experience with fractions up to 100. 4th grade math opens them up to a greater understanding of measurement techniques, geometry and algebraic thinking. It will be a challenging year as they are presented with many new and complex concepts.

Time4Learning teaches a comprehensive fourth grade math curriculum using fun, fourth grade math activities to build a solid math foundation. Help your child excel in math, learn more about Time4Learning’s fourth grade math lessons, curriculum, activities and worksheets.

Fourth Grade Math Curriculum and Standards – Lessons, Activities, Worksheets – Number Sense and Operations

During fourth grade math, children compare and order numbers, recognizing equivalent or non-equivalent numbers. This year they are expected to know basic multiplication and division facts from memory. They’ll learn the inverse relationship between multiplication and division and demonstrate their understanding by writing fact families.

Fourth grade math students learn about the identity, commutative and associative properties of addition. They’ll review the zero and identity properties of multiplication. They’ll learn the commutative, associative, and distributive properties of multiplication. They should be able to predict the relative size of solutions in addition, subtraction, multiplication, and division of whole numbers, the addition and subtraction of common fractions, and the addition and subtraction of decimals to hundredths.

Expanded notation will be introduced during fourth grade math. Children are taught the value of a given digit in numbers from hundredths to millions, including writing and interpreting expanded forms of numbers. They learn to show numbers in bases other than base ten, for example, base five, or base eight. Using estimation the children choose, describe, and explain strategies and discuss the reasonableness of their solutions for real-world problems. They will be asked to estimate quantities of objects to 500 or more, then to justify and explain the reasoning for their estimations.

Fourth grade math students will be expected to multiply by multiples of 10, 100, and 1,000. They should recognize and demonstrate multiplication patterns by now. They will use multiplication to solve real-life problems of up to three digits by one digit. Using models they will identify perfect squares to 100. In division, fourth grade math students demonstrate an understanding of the rules of divisibility for 2, 3, 5, 9, and 10. They’ll solve real-world problems having divisors of one digit and dividends of three digits, with and without remainders.

Use of fractions will be an important part of fourth grade math work. They’ll work with fractions whose denominators include 2, 3, 4, 5, 6, 8, 10, 12, 20, 25, 100, and 1000. The children will compare and order fractions to hundredths, locate fractions on a number line and use fractions in diagrams. They will recognize that two fractions are equivalent or non-equivalent and learn to add and subtract fractions using drawings, story problems and algorithms.

Study of decimals will become an important part of math from now on. Fourth grade math students learn about decimals through the hundredths. They’ll learn to use decimals including money notation to translate problem situations into diagrams and models. They’ll be able to recognize equivalent and non-equivalent decimal numbers and compare the decimal number system with the Roman numeral system using Roman numerals I, V, X, L, C, D, and M.

The 4th grade math word problems are more complicated and can require strong language arts. Expect a lot of practice of 4th grade math skills to help 4th grade math students past those 4th grade math tests and quizzes.

My daughter always liked learning, but Time4Learning has turned “like” into love! I’ve never seen her so excited to do lessons, before!

It’s amazing how quickly my kids are learning difficult concepts. The animation really helps them apply the lessons to something tangible!

Fourth Grade Math Curriculum and Standards – Lessons, Activities, Worksheets – Measurement

During fourth grade, math students use a wide variety of tools and procedures to measure length, area, volume, and perimeter. They investigate angle measures, learning about the common angles of 45°, 90°, and 180° (straight angle). They’ll learn to use these angles as reference for measurement of other angles.

Fourth grade math students solve real-world problems by measuring length to the nearest half-inch or centimeter; weight to the nearest ounce or gram; capacity; angles; and more. They learn about millimeters, quarter-inches, feet, yards, meters; pounds, ounces, kilograms, grams; cups and milliliters. They also learn about perimeter, area, and volume. During fourth grade they use non-standard or indirect ways to compare lengths. They use customary and metric units. Using multiplication and division they’ll convert units within the customary or metric system. The students learn to estimate area, perimeter and irregular polygons using graph paper, geoboards, or other means. They also estimate the volume of a rectangular prism.

Continuing their study of time, fourth grade math students learn about many time units including decades, hours, minutes and seconds. They learn about time to the nearest five-minute interval. They use schedules, calendars and elapsed time to solve real-world problems.

Fourth grade math students estimate and record temperatures to the nearest five-degree interval. They solve real-world problems involving measurement of Fahrenheit and Celsius temperatures. They estimate money to the nearest dollar.

Learning the Math Facts, Where do they fit in building a math foundation?

*Math Standards are defined by each state. Time4Learning bases its use of standards on the national bodies that recommend curriculum and standards and the interpretations of it by a sampling of states notably Florida, Texas, and California.
