Several important geometric terms that hold extreme importance in later grades are included in this chapter. The topics introduced will not only help build a foundation in geometry but will also help to easily grasp the higher-level concepts in the later grades. The main themes covered here are - basic geometry, polygons, triangles and quadrilateral.
A fraction represents a part of a whole or generally, any number of equal parts. Some of the important concepts that you will be learning in this chapter includes Types of Fractions, Addition of Fractions, Subtraction of Fractions, Multiplication of Fractions, Comparing Fractions, Simplest Form of Fractions and Representation of Fraction on a Number Line.
