A negative sentence or statement states that

something is not true or incorrect. In order to

change an affirmative or positive sentence in the

simple present tense into a negative sentence, we

use do not or does not before the Principal Verb.

Do is used with I, YOU and plural subjects. Does is

used with singular subjects like he, she, it etc.

EXAMPLES: She sings.

She does not sing.

Tom writes poems.

Tom does not write poems.

You always win the race.

You do not always win the race.

NEGATIVE AND INTERROGATIVE

SENTENCES

If the affirmative sentence contains the auxiliaries

is/am /are , the negative sentence is formed by

putting not after is/am/are.

Examples: He is a dancer.

He is not a dancer.

They are my neighbours.

They are not my neighbours.

If the affirmative sentence contains the primary

auxiliaries has/have , the negative sentence is

formed by putting do not or does not before

has/have.

Examples: Maira has a red car.

Maira does not have a red car.

They have three flats.

They do not have three flats.

If the affirmative sentence contains a modal

auxiliary verb ( e.g may, can, shall, will, should,

etc),

the negative sentence is formed by putting not

after the modal auxiliary verb.

Examples: Raima can draw.

Raima cannot draw.

They will come.

They will not come.

INTERROGATIVE SENTENCES

The Simple Present Tense has the following

structure.

Subject + present tense form of the verb

e.g The sun sets in the west.

The boy plays the flute.

In order to change an assertive sentence in the

simple present tense into an interrogative

sentence, we use do or does as the first word

followed by the subject, verb and the object.

e.g The boy plays the flute.

Does the boy play the flute?

I jump high.

Do I jump high?

If the interrogative sentence is in the negative, we

begin it with do not (don’t ) or does not ( doesn’t).

E.g Don’t you want an ice –cream?

Doesn’t he play cricket?

The question words who, whom, whose, when,

why, where, which, how etc , sometimes precede

do and does.

e.g Whom are you looking for?

Where do you learn piano?

How many cakes do you want?

When the affirmative sentence contains the

primary auxiliaries is, am, are, has, or have, the

interrogative sentence will begin with these

words.

e.g She is a dancer.

Is she a dancer?

He has many friends.

Has he many friends?

When the affirmative sentence contains can, may,

will, shall, etc, the interrogative sentence will

begin with these words.

e.g She can go.

Can she go?

You may take this book.

May I take this book?

QUESTION TAGS

Question tags are the short questions that we put

at the end of sentences.

Positive/Negative

If the main part of the sentence is positive, the

question tag is negative.

e.g He is a doctor, isn’t he?

You work in a bank, don’t you?

If the main part of the sentence is negative, the

question tag is positive.

e.g You haven’t done your project, have you?

She isn’t well, is she?

LESSON – BASIC GEOMETRICAL CONCEPTS

ANGLES

When two rays have a common end point they from an angle. In this figure two rays OA

and OB have a common end point O. So they form an angle AOB. The common end point

is called the Vertex and rays OA and OB are the arms of the angle.

The unit of measurement of an angle is degree (°).

The angle is represented by the symbol ∠. The angle is read as ∠XYZ..

Always remember, while naming the angle, the vertex is always in the centre.

The figure formed by two rays with the same initial point is called an angle.

Interior and Exterior of an Angle

The shaded portion between the arms BA and BC of the angle ABC can be extended

indefinitely.

This portion is called the interior of the angle. X is a point in the interior of the angle. The point Y lies in

the exterior of the angle. The point Z lies on the angle.

∠1 is called the interior angle and ∠2 is called the exterior angle.

Measuring an Angle using a Protractor

Protractor:We measure the size of an angle by using protractor

It is a semicircular protractor which is marked in degrees from 0° to 180° from

left as shown in the adjoining figure.

1. Use your protractor to draw 60°.

Thus we find ∠ AOB = 60°.

2. Use your protractor to draw 90°.

Thus we find ∠ AOB = 90°.

Types of Angles

1. Acute Angle: An angle whose measure is more than 0o but less than 90° is

called an acute angle.

2. Right Angle:An angle whose measure is 90° is called right angle.

3. Obtuse Angle: An angle whose measure is greater than 90° but less than 180° is

called an obtuse angle.

4. Straight Angle: An angle whose measure is 180° is called a straight angle

5. Reflex Angle: An angle whose measure is more than 180° but less than 360° is

called a reflex angle.

6. Zero Angle: An angle whose measure is 0° is called a zero angle.

7. Complete or Whole Angle: An angle whose measure is 360° is called a complete

or whole angle.

Comparision of Angles: Thus, we can say that:

Acute Angle < Right Angle < Obtuse Angle < Straight Angle < Reflex Angle<Whole Angle

Pairs of Angles

1. Complementary Angles:

Two angles whose sum is 90° are called complementary angles .

Here, ∠AOB = 40° and ∠BOC = 50° Therefore, ∠AOB + ∠BOC = 90°

Here, ∠AOB and ∠BOC are called complementary angles.

For Example:

(i)Complement of 30° is → 90° - 30° = 60° (ii) Complement of 45° is → 90° - 45° = 45° (iii) Complement of 55° is → 90° - 55° = 35° (iv) Complement of 75° is → 90° - 75° = 15°

2. Supplementary Angles:

Two angles whose sum is 180° are called supplementary angles . Here, ∠PQR = 50° and ∠RQS = 130° are supplementary angles.

∠PQR + ∠RQS = 180° Hence, ∠PQR and ∠RQS are called supplementary angles .

For Example:

(i) Supplement of 55° is 180° - 55° = 125°

(ii) Supplement of 95° is 180° - 95° = 85°

(iii) Supplement of 135° is 180° - 135° = 45°

(iv) Supplement of 150° is 180° - 150° = 30°

3. Adjacent Angles:

Two non – overlapping angles are said to be adjacent angles if they have: (a) a common vertex (b) a common arm (c) other two arms lying on opposite sides of this common arm.

In the above given figure, the ∠AOB and ∠BOC form a pair of adjacent angles.

4. Vertically Opposite Angles:

Two angles formed by two intersecting lines having no common arm are

called vertically opposite angles.

When two lines intersect, then vertically opposite angles are always equal.

∠1 = ∠2

∠3 = ∠4

5. Linear Pair: Two adjacent angles are said to form a linear pair if their sum is 180°.

<AOC + <BOC = 180° ( By linear pair)

Ls-10 Rocks, Minerals and Metals

Rocks – Rocks are found everywhere on earth. Most rocks are

combinations of one or more minerals. Some rocks, such as

limestone contain remains of animals and plants.

Scientists who study rocks are called petrologists.

Kinds of rocks – Depending on the nature of their formation, rocks are

of three types:-

Kinds of rocks

Igneous Rocks Sedimentary Rocks Metamorphic Rocks

Granite

Basalt

Pumice

Obsidian

Limestone

Sandstone

Conglomerate

Shale

Dolomite

Marble

Slate

Gneiss

Quartzite

Formation of igneous , metamorphic and sedimentary rocks-

Formation of igneous rocks

Ignis is a Latin word which means ‘heat’ or ‘fire’.

Formed from Formed from Formed from

Vent

Magma

Chamber

Uses of igneous rocks-

Pumice Granite Obsidian Basalt

1) Granite is used in constructions, for example, kitchen counters and

floors.

2) Obsidian is used to make ornaments and jewellery.

3) Basalt is used in the construction of roads and building materials.

4) Pumice is used as a foot scrub . It is used in cosmetic and cleaning

industries.

Uses of sedimentary rocks –

Sandstone Conglomerate Shale Limestone

1) Sandstone was used in constructing monuments such as the Red

Fort and the Qutub Minar.

2) Conglomerate is used as a building material.

3) Shale is used to make tile roofs, cement, bricks and terracotta pots.

4) Limestone is used for making lime, bricks, glass, cement and chalks.

Uses of Metamorphic rocks-

Marble Slate Gneiss Quartzite

1) Marble is used for making statues, floors and building material.

2) Slate is used to make blackboards, slates and roofs.

3) Gneiss is also known as an ornamental stone .It is used as a building

material to make floor, working shelves or as gravestones.

4) Quartzite is commonly used in the glass and ceramic industries.

Assignment

I) Fill in the blanks :-

1) Scientists who study rocks are called -------------------.

2) Limestone contain remains of ---------------and ---------------.

3) Red Fort in Delhi is built with ------------------------.

4) Chalk is a kind of --------------------.

5) Limestone undergoes heat and pressure and form ---------------.

6) ---------------------is formed from granite.

II) Name the following :-

1) Any two types of igneous rocks.

2) Any two types of sedimentary rocks.

3)Any two rocks used for making statues.

III) Answer the following questions :-

Q-1 Explain the formation of igneous rocks with a well

labelled diagram.

Ans-1 Igneous rocks are formed when magma cools and hardens.

Sometimes, the magma cools inside the Earth. In some cases, it erupts on

to the surface from the volcanoes (in this case, it is called lava). When the

magma from under the Earth’s crust (lava) comes out during volcanic

eruptions, some of it gets spread over the Earth’s surface. Slowly and

gradually, it cools down and forms rocks.

Q-2 How are sedimentary rocks formed?

Ans-2 Sedimentary rocks are formed by the deposition of sediments, over

time . When the water flows down through a mountain slope, it breaks

some of the rocks of the mountain that come on its way. Likewise, strong

wind and heavy rainfall also cause breakage of rocks into smaller pieces.

These small pieces of rocks and soil particles are carried away by flowing

water or wind to some other places. This way, layers of sediments pile up

at a particular place and get cemented over thousands of years, thus

forming sedimentary rocks.

Q-3 Write the uses of the following rocks :-

i) Slate ii) Pumice iii) Limestone iv) Granite

Ans-3 1) Slate - It is used to make blackboards, slates and roofs.

2) Pumice - It is used as a foot scrub. It is used in cosmetic and cleaning

industries.

3) Limestone - It is used for making lime, bricks, glass, cement and

chalks.

4) Granite- It is used in constructions, for example, kitchen counters

and floors.

Subject: Social Studies Class: V

LESSON: 15 TOWARDS FREEDOM [Contd…]

** CONTENT OF THE LESSON:

AFTER THE REVOLT ➢ The British suppressed the First War of

Independence. Many factors were responsible for the failure of the 1857 Revolt: -

• The revolt did not spread to all parts of

India.

• Indian soldiers did not have sufficient

money and good weapons.

• The Revolt was not organized properly. ➢ The rule of the East India Company ended in 1858.The administration of

India was taken over by the Government of England.

SOCIAL & RELIGIOUS REFORMERS ➢ The British introduced modern education in India. ➢ Educated Indians introduced many social and religious reforms.

(Reforms means the improvement of something by removing faults) ➢ Reformers such as Raja Ram Mohan Roy, Ishwar Chandra Vidyasagar

and Debendranath Tagore were active during this period. ➢ They strongly protested against social practices such as sati, female

infanticide, child marriage and the caste system. They also encouraged widow remarriage and education of women.

Topics: After The Revolt, Social & Religious Reformers, Rise of Nationalism

AFTER

RISE OF NATIONALISM

➢ Educated Indians realized that the British wanted to keep India poor and backward. This realization united the Indians.

➢ The growing feeling of nationalism resulted in the formation of the Indian National Congress in 1885.

➢ The Indian National Congress was formed by an Englishman named Allan Octavian Hume (A.O. Hume). Its first session was held at Bombay (now Mumbai).

➢ The first session of the Indian National Congress was attended by 72 delegates (A delegate is a person

who is chosen to vote or make decisions on behalf of a group

of other people, especially at a conference or a meeting) from all over India in December 1885. The President of this session was Womesh Chandra Bonnerjee (W.C Bonnerjee).

➢ Thereafter the Congress met every year in different

cities. It awakened the spirit of unity among the Indians. ➢ The growing popularity of the Congress worried the British. ➢ To suppress the rising spirit, the British made strict laws. They also used the

policy of divide and rule to prevent the Hindus and Muslims from uniting.

MS-EXCEL (CONTD.):

USE OF SOME COMMON FORMULA:

One of the most powerful features in Excel is the abilityto calculate numerical information using formulas.

Just like a calculator, Excel can add, subtract, multiply, and divide.

All formulas in Excel must begin with an equals sign (=). This is becausethe cell contains, or is equal to, the formula and the value it calculates.

Understanding cell references

While you can create simple formulas in Excel using numbers (forexample, =2+2 or =5*5), most of the time you will use cell addresses to createa formula. This is known as making a cell reference.

In the formula below, cell A3 adds the values of cells A1 and A2 by making cellreferences:

When you press Enter, the formula calculates and displays the answer in cellA3:

If the values in the referenced cells change, the formula automaticallyrecalculates:

By combining a mathematical operator with cell references, you can create avariety of simple formulas in Excel.

SUM():

The SUM function is the first must-know formula in Excel. It usuallyaggregates values from a selection of columns or rows from yourselected range.

=SUM(number1, [number2], …)

Example:

=SUM(B2:G2) – A simple selection that sums the values of a row.

=SUM(A2:A8) – A simple selection that sums the values of a column.

PRODUCT:

“E4*G4” uses the arithmetic operator multiplication (*) tomultiply the value of the cell address E4 and G4, and finallygetting the result as product.

Look at the example, in this example we have prepared a billfor 3 items and in the cell ‘I4’ we are taking the product of twocell contents i.e. (5 and 90) ‘E4 AND G4’.

After pressing ENTER key, we will have the result in I4 asproduct.

Now, we will find the total of ‘I4+I5+I6’ in I8 cell using SUM().

After clicking enter we will get the TOTAL.

PROJECT WORK:

Create a ‘BILL’ of any random store for 10 items of your choice andfind the total amount for the same.

Example has been given for the reference:
