CBSE Class 3 Mathematics:

              When compared to CBSE Class 3, CBSE Class 2 Mathematics covered various simple topics on Addition, subtraction, multiplication without carry, place value in numbering system, simple division, etc., But in CBSE Class 3, next level mathematics is taught to enhance and trigger the brain of the child. For this, they have included the portions just similar to that of Class 1 and Class 2 but in little higher level. Among all the subjects of CBSE Class 3 like Mathematics, Science, Hindi and English let us check out the syllabus of Mathematics below.

In class 1 and class 2, addition and subtraction were little simpler with simple two digit and three digit additions and simple word problems. But in class 3, next level of addition such as four digit addition, subtraction with or without borrowing, addition and subtraction word problems are covered.

Examples:

1. Answer the following:

In division it covers, division by 10 and 100, division with two digit number, multiplication and division mixed problems, division word problems, etc.

Examples:

• Fractions:

         Fractions are the important part of mathematics and it is very important to understand it clearly. Fraction comes as proper and improper fraction. The terms numerator and denominator are very important in the concepts of fraction.

Numerator = Number that is above the fraction line. Example: 2 in 2/3

Denominator= Number that is below the fraction line. Example: 3 in 2/3

Proper fraction has numerator smaller than the denominator whereas improper fraction has numerator larger than denominator. An improper fraction can be converted into a mixed fraction having a proper fraction and integral part. Fractions can be added, subtracted, divided and also multiplied.
