  2-D Shapes In geometry,  2d shapes  and 3d shapes are explained widely to make you understand the different types of objects you come across in real life. These shapes have their own pattern and properties. Depending on many factors, such as angle, sides, length, height, width, area, volume, etc., the shapes can vary. 2D Shapes Definition In maths, 2d shapes can be defined as the plane figures that can be drawn on a flat (or plane) surface or a piece of paper.  All the 2d shapes have various parameters such as  area and perimeter . Some of the 2d shapes contain sides and corners, whereas some have curved boundaries. Geometric shapes  Geometric shapes are regular shapes. Most geometric shapes have straight lines, angles and points. The two exceptions to this rule are circles and semi-circles.  The ten basic geometric 2D shapes are: Circle Triangle  Semi-circle  Square Rectangle Parallelogram Rhombus Trapezium  Kite Polygon 2-D shape names and facts Circle     A circle is a two-dimensi

CONVERTING FRACTIONS   CONTENT: Kinds of fraction. Converting improper fraction to mixed fraction. Converting mixed fraction to improper fraction. Quiz Hello students! Today lets learn how to convert improper fraction to mixed fraction and mixed fraction to improper fraction. Before that lets recall the types of fractions .  Kinds of Fractions There are three types of fractions. Types of Fractions Proper Fraction  -the numerator is less than Denominator Improper Fraction - the numerator is greater than the Denominator Mixed Fraction - written as a combination of a whole number and a fraction. Converting Improper fraction to a mixed fraction Step 1: Divide numerator with the denominator. Step 2:   Take quotient as whole number and remainder as the numerator of proper fraction. Step 3: The Denominator will be the same   Example 1 Convert 3/2 into Mixed Fraction. Solution: Given Fraction: 3/2 Divide the Numerator by the Denominator On dividing 3 by 2 We get Quotient = 1 R

FRACTION AND ITS TYPES Hello students! today lets learn about fraction and its types. What is fraction?      When an object is divided into a number of equal parts then each part is called a faction. A fraction denotes a part of a whole or a collection. A fraction consists of a Numerator and a Denominator.  The numerator tells how many parts out of all are there. The denominator tells how many total parts are there.  FRACTION IN REAL LIFE: Fractions are used in life situation such as, To express time as quarter past 3, half past 4, quarter to 5. To say the distance between two places as half a kilometre / two and half kilometre. If a pizza is divided into two equal parts, then each part is equal to half of the whole pizza If we divide a slice of watermelon into three equal parts then each part is equal 1/3rd of the whole TYPES OF FRACTION: There are three different types of fractions. They are: Proper fraction Improper fraction Mixed fraction       PROPER FRACTION:           If a numer
