Six Math Skills Your Child Has To Learn In 3rd Grade

Math is an important subject that helps students develop problem-solving skills, logical reasoning, and critical thinking. Math for 3rd graders is a more complex version of the concepts the students already know. Therefore, they need to master new skills to keep up with their peers and prepare for higher grades.

In this article, we will explore six math skills that your child should learn in 3rd grade.

1. Place value and addition and subtraction with regrouping

Third graders should learn to understand place value and add and subtract multi-digit numbers using regrouping. Place value is the value of each digit in a number based on its position.

For example, in the number 345, the 3 is in the hundreds place, the 4 is in the tens place, and the 5 is in the ones place. To add and subtract multi-digit numbers, students need to understand place value and use regrouping, also known as carrying and borrowing.

2. Multiplication and division

The problems in math 3rd grade students solve include multiplying and dividing basic facts up to 10. Therefore, they need to understand multiplication properties that include commutation and association as well as the relationship between multiplication and division. Students should also learn to use strategies like skip counting, repeated addition, and arrays to solve multiplication and division problems.

3. Measurement

Students in 3rd grade should learn how to measure length, weight, capacity, and time using standard units of measurement. This includes understanding concepts like inches, feet, pounds, ounces, cups, pints, quarts, and hours. Third-graders should also learn how to use a ruler and other measuring tools accurately and convert between different measurement units.

4. Geometry

In 3rd grade, students get acquainted with basic geometry concepts, such as identifying and describing two-dimensional shapes and three-dimensional figures, as well as understand the properties of these shapes, such as sides, angles, and vertices. Students should also learn how to compare and classify shapes based on their attributes.

5. Fractions

3rd grade kids math involves understanding and representing fractions, including fractions with denominators of 2, 3, 4, 6, and 8. Their learning includes understanding concepts like unit fractions, equivalent fractions, and comparing fractions. Students should know how to add and subtract fractions with the same denominator and solve word problems involving fractions.

6. Graphs

Third graders should learn how to interpret and create different types of graphs, such as bar graphs, picture graphs, and line plots. They should be able to read and label the axes on a graph, interpret the data, and answer questions about the data using the graph. Students will also create a chart by collecting and organizing data and draw conclusions based on the data.


In 3rd grade, students should learn math skills, including place value, addition and subtraction with regrouping, multiplication, and division. The skills acquired in this period will help your child feel confident in the following grades. Overall, math for 3rd graders is an essential subject that should be taken seriously.
