We have learnt about the fractions. fractions included proper, improper and mixed fractions as well as their addition and subtraction. Also studied comparison of fractions, equivalent fractions, representation of fractions on the number line and ordering of fractions.

We have also learnt decimals included, their comparison, their representation on the number line and their addition and subtraction.

How Well Have You Learnt About Fractions?

A proper fraction is a fraction that represents a part of a whole. E.g. 7/4, 8/4 Continue Learning

3.1 Data Handling

As we know about the data is collection in calculated form. The collection, recording and presentation of data help us organize our experiences and draw inferences from them.

Hear You will learn across some more kinds of data and graphs.

3.2 Collecting Data

Data can be row or mixed but whenever we make collection of data. We should know about data types. So, before collecting data, we need to know what we would use it for. Continue Learning

4 Simple Equations

An equation is a condition based on a variable that satisfied both sides of RHS (Right Hand Side) and LHS (LHS). We have learnt in class VIth, Algebra.

Hear we learn about the Equations that has in Simple formed.

4.1 A Mind-Reading Game!

In this section we learn and solve the equation based game. The equation based game blow the light of idea in mind of several thoughts.

For Example − Continue Learning

5.1 Introduction

We have learnt about the lines and angles, a line segment have two end points and an angle is formed when lines or line segments meet.

If we extend the two end points in either direction endlessly, we get a line.

As we know angles are the corners are formed when two lines or line segments intersect at a point.

5.2 Related Angles

Complementary Angles Continue Learning

6.1 The Triangle and properties

A triangle is a simple closed curve made of three line segments. It has three vertices, three sides and three angles.

6.2 Medians of a Triangle

The line segment AD, joining the mid-point of BC to its opposite vertex A is called a median of the triangle.

6.3 Altitudes of a Triangle

As we learn about the triangle, a triangle is formed with three liens. Let's make a triangular shaped cardboard △ABC. Place it upright on a table. Continue Learning

7.1 Congruence of triangles

The relation of two objects being congruent is called congruence.

When two triangles have the same shape and size, or if one have the same shape and size as the mirror image of the other is known as congruent.

The symbol of Congruence is ≅. Continue Learning

8.1 Introduction

As sound says comparing some similar types of fraction with quantities.

There are many occasions when we compare two quantities. The ratio for two different comparisons may be the same. Remember that to compare two quantities, the units must be the same.

8.2 Equivalent Ratios

When different ratios can also be compared with each other to know whether they are equivalent or not. If these like fractions are equal, we say the given ratios are equivalent. Continue Learning

9.1 Rational Numbers

There are many numbers used for many purpose were called counting numbers or natural numbers. we learnt the whole numbers, i.e., 0, 1, 2, 3, ... The negatives of natural numbers were then put together with whole numbers to make up integers. Integers are ..., −3, −2, −1, 0, 1, 2, 3, .....

The word ‘rational’ arises from the term ‘ratio’. Extending the number system, from natural numbers to whole numbers and from whole numbers to integers the number can be expressed as fraction include all the integers, fractions and decimal known as Rational Numbers. Continue Learning

10.1 Introduction

Geometry teaching us about the area, perimeter, volumes etc of shapes. We had learnt in previous classes of many shapes.

10.2 Construction of a Line Parallel to a Given Line, Through a Point not on the Line

Here go to learn about the Constructions of Parallel Line with the help of point by using of ruler (scale that using of measurement available in your instrument box.) and compasses. Continue Learning

11.1 Perimeters and Area

We learnt about the perimeters of plane figures and areas of squares and rectangles. Perimeter is the distance around a closed shaped while area is the part of plane or region occupied by the closed shaped.

Here we will learn much about the Perimeter and Area of more shapes.

11.2 Squares And Rectangles

As we learnt about the squares that's one kind of regular polygon and has four equal sides and also similar about the rectangle that Continue Learning

12.1 Algebraic Expressions

As we know the Algebra says an equation, an expression with variable.

Here we will know how algebraic expressions are formed, how they can be combined, how we can find their values and how they can be used.

12.2 How Are Expressions Formed?

An Algebraic expression must have a variable. A variable can take various values. The value of variables has not fixed, but while any variable has any fixed value than that's says constant. Continue Learning

13.1 Exponents and Powers

The term exponent says a number how many times to use and in a multiplication. Exponent is a operation and written as bⁿ, involving two numbers, the base b and the exponent or power n.

Here go to learn about these.

13.2 Exponents

Exponent means write large numbers in a shorter form using exponents. Continue Learning

14.1 Symmetry

The Symmetry is an important geometrical concept, commonly exhibited in nature and is used almost in every field of activity.

A figure has a line symmetry, if there is a line about which the figure may be folded so that the two parts of the figure will coincide.

14.2 Lines of Symmetry For Regular Polygons

As we know the polygon is a closed figure made of several line segments. The polygon made up of the least number of line segments is the triangle. Continue Learning

15.1 Introduction: Plane Figures And Solid Shapes

We all have learnt more about the shapes. The various shapes of polygons, triangles, squares etc. here we visualize about them.

Around us there many things and have different shapes. One thing common about most of these objects is that they all have some length, breadth and height or depth.

That is, they all occupy space and have three dimensions. Hence, they are called three dimensional shapes. Continue Learning
