A times table is a table containing the product of a number when multiplied in an ordered sequence. Third grade students will learn the times tables of numbers starting from 1 to 20. 


Table of 6


Table of 19


Table of 28


Patterns in multiplication Table

The easiest way to learn the multiplication of numbers is to observe the table for patterns. The multiples of most numbers follow a particular pattern. Third grade students will develop a keen eye for noticing these patterns, and it will help them perform calculations quickly. 


Multiplication of numbers using Properties

Just like the properties third grade students learned about addition and subtraction, learners will be exposed to properties related to multiplication as well. Students can use these properties to solve math expressions having multiplication operations quickly.

Division Strategies

Once the students are familiar with addition, subtraction, and multiplication, they are now ready to use these concepts together to handle division or sharing into equal groups problems as well. In this section, 3rd grade students will learn strategies they can use while dividing two numbers.


Fraction is another fundamental concept introduced to Grade 3 learners in mathematics. Students have learned the numbers used for counting wholes. Fractions are numbers that are used to represent quantities that are less than a whole. Here, they will solve math problems for third graders and learn about the applications of fractions.

Fraction Equivalence and Comparison

A given quantity can be divided into parts of various sizes and can be thus represented in multiple ways depending on size of parts being referred.  Equivalent fractions are fractions that have different numerators and denominators but still have the same value. Here, 3rd grade students will learn to identify equivalent fractions and compare different fractions using visuals and daily life problems.

Time, Liquid Volume, and Mass

Now that students are familiar with all four basic operations of math, they will learn how to apply them in the real world. Students will revisit the concepts of mass and length measurements and have an in-depth study on them. Third grade math students will also be introduced to the concepts of volume and mass through estimation, comparison,  non standard units and later metric units .

Understand Time

Understanding the concept of time strikes off one of the skills from the third grade skills checklist. It will help them learn to manage their time and schedule tasks on their own.


Estimating the time

As third graders are familiar with the concept of estimation of numbers, they can apply the same idea to estimate time. This will help them solve third grade math problems related to time much quicker. 


Measurement of length

Third graders have already learned the basics of measuring the length of objects. Here, they will learn about this concept in detail and solve math problems based on it.

Two-Dimensional Shapes

Students have already learned the basics of two-dimensional shapes in their first and second grades. Here, they will look at individual shapes and learn the properties associated with them. Learning these properties will help students recognize how these properties  are utilized in the  objects they interact with in everyday life.


Types of Quadrilaterals

A quadrilateral is a shape that has four sides. Third grade students will be introduced to the various types of quadrilaterals and their properties.



A rectangle is a shape whose opposite sides are equal. Students will learn properties associated with a rectangle and solve problems based on it.

Regular Hexagon



Represent and Interpret Data

Third grade math students have already learned how to perform basic operations with numbers and the properties of different shapes. Now, they learn how to use math as a communication tool. Representation of interpretation of data is important because it allows students to communicate ideas using a visual representation. Here, third graders will learn methods used for the visual representation of data.

Perimeter and Area

Perimeter and area are qualities associated with two-dimensional shapes. We use these quantities to express the size of various shapes. As the size of a shape increases, its area and perimeter increase. Here, 3rd grade students will learn the meaning of perimeter and area, units required and how it is calculated for basic shapes.


Perimeter and Area

Students are exposed to understand  how the total length of the boundary of a shape is known as the perimeter. The extent of the region occupied by the shape is known as its area. 


Understanding Perimeter

A two-dimensional shape is a region enclosed by a certain number of lines. The total length of all sides, or the length of the boundary, is known as the perimeter of a shape.  


Perimeter of Triangle

A triangle is a three-sided shape. The sum of the lengths of the three sides is known as the perimeter of the triangle. 


Perimeter of a Parallelogram

A parallelogram is a four-sided shape in which the opposite sides are equal and parallel. The total length of the four sides of a parallelogram is known as its perimeter. 


Area of Shapes

The area of a shape is the amount of region occupied by its boundary. As the size of the shape increases, the area occupied by it also increases. 


Measurement of Area using standard units

The area can be measured using different methods. The easiest and the most reliable way of measuring the area of a shape is to use standard-sized squares. Students can count the number of standard units occupied by a shape to find its area.  


Measuring area using Distributive property

Measuring area using the distributive property is one of the many methods that can be used to measure the area of a shape. Here, students will be introduced to an application of the distributive property, backed by third grade math problems. 


Difference Between Area and Perimeter

Area and perimeter are two parameters used to describe the size of a shape. Even though they are used for similar applications, the two parameters are totally different. Learn the difference between area and perimeter and solve 3rd grade math problems related to the concept.
