Dividend
The dividend is the number that is being divided in a division operation.
Divisor
The divisor is the number that divides a dividend in a division operation.
Remainder
The remainder is the left-over value after performing a division operation. A remainder is left when a divisor cannot completely divide a dividend.
Division by special numbers
Division by certain numbers follows a special pattern which can help solve division problems efficiently. Here, students will solve third grade math problems to be throughout with the division by special numbers.
Fractions
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.
Introduction of fractions
Fraction is about representing parts of wholes. Here, students will learn the meaning of numerator and denominator in a fraction. They will also learn some examples of fractions and their applications in real life.
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.
Equivalent fractions and their comparison
The fractions that have different numerators and denominators but still have the same value are known as equivalent fractions. Students will learn the concept and meaning of various equivalent fractions through visuals and ordering problems to solve fraction related math problems for third graders efficiently.
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.

A graph is a diagram that shows the relationship between various quantities or variables. Third grade students need to learn how to collect data, represent data and interpret graphs as this will help them organize and use the information available around them effectively.
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
