Fourth Grade Math Common Core State Standards and Curriculum

in 4th grade, math standards begin incorporating higher math concepts into the curriculum. Students were introduced to some of these concepts in the third grade. In the fourth, these concepts will be deepened and expanded upon. Rather than the introduction of new math concepts, 4th grade Common Core math standards aim to perfect and refine ideas already established. Like a spiral, these mathematical concepts move downward, clarifying more and more. Fourth grade has a reputation for being difficult, but this doesn’t have to be the case. By understanding what Common Core math standards for fourth grade require, students are more likely to have a successful academic year.

CCSS 4th Grade Math: What Your Student Should Already Know

Levels of competency in previous grades impact the success of future grades in the design of Common Core math standards. Grade 4 success in math is directly affected by that achieved in the third grade. This is because most of what students learn in the fourth grade is dedicated to creating deeper and more flexible understanding of what third graders learned. By the beginning of fourth grade, children should be able to:

Add and subtract digits up to the thousands place with ease.

Addition equations involving only tens and ones should not require pencil and paper. Mental strategies should be used for these types of equations. This means that third grade students should be able to multiply 3x9 in their minds without having to draw arrays or use other grouping strategies. Students should be familiar with solving addition and subtraction problems with up to three digits using vertical equation strategies.

Understand the base ten system (to the thousands place.)

Place value and what each refers to should be fluent up to 4 digits of a number. The base ten system should be familiar to students and incorporated into mental math strategies. Students should have the ability to break down numbers into groups based on place value, both mentally and on paper. For example, students should be able to see 749 as 7 groups of 100, 4 groups of 10, and 9 groups of one.

Multiply fluently (products up to 100.)

Students should understand the meaning of multiplication and the definition of a product. Multiplying fluently within 100 should be familiar and systematic before working on fourth grade Common Core math standards. Students should have multiplication tables of equations using two numerals with one digit each memorized by the end of third grade. These include 1x1 all the way up to 9x9. Students should also understand the commutative property of multiplication. This property refers to the fact that changing the order of numbers in a multiplication problem does not change the outcome. For example, if 9x4=36, then 4x9 is also known as 36.

Divide numbers within 100.

By the end of third grade, students should understand the meaning of division and the definition of a quotient. Students should apply mental and written strategies to divide within 100. Students should also understand the connection between the practice of both division and multiplication. They should use this relationship as a strategy in solving division problems. For example, if 5x3=15, then it is known that 15/5=3. It is also known that 15/3=5.

Be familiar with unit fractions and comparing fractions.

Unit fractions, which are those that represent one part of a total number of parts (ex. 1⁄4), should be familiar to students. Students should also have experience comparing fractions based on their denominators. For example, a student should understand that 1⁄4 is larger than 1⁄5 because a piece of pie cut into 4 pieces is larger than a piece of pie that has been cut into 5 pieces. In the same vein, 1⁄4 is smaller than 1⁄2 because a piece of pie cut into 4 pieces is smaller than a piece of pie cut into 2 pieces. Identify shapes, their common properties, and find area of rectangular arrays. Students should be able to name shapes, how they are similar, and how to describe them (properties) by the end of 3rd grade. They should also be able to find the area of shapes that are square or rectangular.

CCSS Math: 4th Grade Curriculum’s 3 Focus Areas

Your student will not spend study time learning new concepts during 4th grade math. Common Core standards instead focus on three areas that expand on those instated during 3rd grade. Focus areas for 4th grade math standards fall into one of three general focus areas. As aforementioned, third grade created the basics for these concepts to be built upon. To further these concepts, fourth graders should have a competent understanding of the framework. If you feel that your student is facing detriment in any of these subjects, make a summer plan to strengthen their math weaknesses. ArgoPrep provides an extensive educational online platform with a wide selection of math materials at the ready.

Math Standards: 4th Grade Focus Area Breakdowns and Study Suggestions

Area 1: Develop multi-digit multiplication and division skills.

Understanding of place value will extend to 1,000,000. In multiplication, students will apply understanding of properties (distributive) to solve equations involving whole numbers with more than 1 digit. Students will also become familiar with factors of numbers from 1 to 100 and understand definitions of prime and composite numbers. For example, students will know that 37 is prime because it has two factors: 1 and 37. Students will also understand that 42 is composite because it has more than two factors, which are 1, 2, 3, 6, 7, 14, 21, and 42. In division, students will create fluency with strategies to solve division problems of multi-digit numbers. Students will also become familiar with remainders in division and estimation strategies.

Area 1 Study Suggestion

With memorization of facts, repetition is key. Timed multiplication worksheets are a fun challenge for students. With multi-digit multiplication, systematic practice of the process is important. ArgoPrep provides extensive workbooks and correlating tutorials explaining each step for a thorough and comprehensive approach. There are other things teachers and parents can do to help with memorization. Online games, flashcards, and using dice and other manipulatives are a good place to start.

Area 2: Operations and comparing of fractions.

Students will learn the concept of fraction equivalence and explain why two fractions are the same. For example, students will understand 2/4 and 1/4 are the same. This is because they are similar expressions of the same part of a whole; by dividing 2 and 4 by their shared factor, 2, 2/4 can be written as 1/2. Students will also practice addition and subtraction of fractions with like denominators. They will also practice multiplication of fractions by whole numbers. Students will also practice decimal notation for fractions involving 1, 10, and 100 as a denominator.

Area 2 Study Suggestion

Fractions create frustration in many students. This is because the numbers (1⁄4, 1⁄5, etc.) can seem like such a foreign concept. One way to combat this problem is to use pictures and manipulatives such as fraction bars and pieces of chocolate. Using real-world examples and situations can help this 4th grade Common Core math standard feel real. Use visuals, such as illustrations or physical examples, chocolate to help them understand what fractions mean. Online videos can help as well. For more help, browse ArgoPrep’s colorful tutorials involving operations with fractions.

Area 3: Analysis and classification of geometric figures based on their properties.

In geometry, students will become familiar with angles and different lines. In the fourth grade they will practice drawing lines and points. They will also identify and sketch line segments and rays. Fourth grade Common Core math standards also require students to learn about the three types of angles (acute, right, obtuse.) They will also recognize parallel and perpendicular lines and use these to analyze various shapes. Students will identify and categorize right triangles while focusing on the symmetry of shapes.

Area 3 Study Suggestion

Practice drawing or tracing shapes with your students. As you go along, ask them to describe the shape: How many sides does it have? Is it symmetrical? Where is the line of symmetry? Using a protractor, ask them to measure angles within shapes. Be sure to identify right angles within shapes. Compare different angles and ask which is the most obtuse or the most acute. It is important that students be able to estimate angle degrees as well as add angles together to make certain degree numbers (i.e. 180.)

Operations & Algebraic Thinking
