The Math concepts in third grade include the fundamentals of number theories, operations and applications. Third grade is the place where students gain knowledge to evaluate and select operations to work out problems. The students learn the application of previously gained basics from first grade and second grade in the third grade.

The third grade concept includes Math lessons with interactive activities, games, measurements and worksheets. Third grade is the place where the children learn the fundamentals of geometry, number operations, spatial sense, measurements, algebras, the analysis of data and the probability.

## Number System in Third Grade:

The number operations in third grade with lessons, worksheets and activities include comparison and arrangements of numbers. Here, the children learn the operation of fraction and decimals with the help of money.

The students compare, arrange, represent, calculate and understand numbers up to 1000. In third grade, the children learn to do addition and subtraction of numbers mentally. They learn to place the value to easily regroup the numbers.

The students in third grade do calculation such as addition and subtraction of four-digit number with regrouping and carrying. They also carry out multiplication and division. They learn to work out word problems with division, multiplication, subtraction and addition.

The children in third grade learn commutative and distributive rules of multiplication. They also learn to explain inverse relationship with addition and subtraction as well as with multiplication and division.

## Measurements with Lessons, Worksheets and Activities:

The students in third grade Math learn new concepts of measurements with oral and written explanations. They use several objects to take the measurement such as the length, the weight, the area, the volume, the perimeter and the capacity in different units. The students use coin and currency, to learn the calculation of money up to $10.

The students of third grade Math also learn to measure time using watches or clocks and date using calendars. They learn and understand the difference between A.M. and P.M. and use specific schedules to solve word problems. The third grade concept includes measurement of time in seconds, minutes and on hourly basis.

The syllabus includes temperature ratings in Celsius as well as Fahrenheit thermometers with an interval of five degrees. The students learn to compare different measurement tools in this level.

## Geometry and Algebra in Third Level:

The third grade concept includes the construction and explanation of two-dimensional and three-dimensional objects, using objects such as toothpicks and straws. The students learn to solve different geometric puzzles.

The children in third grade Math learn to compare, classify and explain all 2D and 3D objects and shapes with vertices, edges and faces. They use 1/4th and 1/2ed turns to execute and find transformation, slides, rotations and flips. They learn to plot coordinates using ideas of battleship.

The third grade concepts of Math help the children to develop the fundamental knowledge of geometrical shapes. They acquire the ability to sort out problems using geometry. They learn to read maps, and eventually, acquire special sense.

The algebraic concepts include the identification, explanation, reorganization and enlarge patterns with more characteristics to identify the relationships. The algebraic learning at a small age helps to distinguish sets and patterns, and creates foundation algebraic variables.

## The Probability and Analysis of Data in Third Level:

The concepts include the collection and arrangements of graphical parameters in chart of Venn diagrams. They also learn to perform different types of probability experiments, predict the outcomes using cards, marbles or dice. The third grade Math includes the teaching of probability calculation of weather and races.

The concept of third grade Math helps the students to learn and implement the application of Math in their everyday life. The fundamental concept of Math is taught in the third grade of studies to help them succeed in life.
