|| '''Slide Number 1'''

'''Title Slide'''
|| Welcome to this Spoken Tutorial on '''Number Line: Integers'''.

|-
|| '''Slide Number 2'''

'''Learning Objectives'''
|| In this tutorial, we will learn how to:
* Use integers to represent quantities in multiple contexts
* Compare integers on the number line
* Change the relative positions of integers on the number line

|-
|| '''Slide Number 3'''

'''System Requirements'''
|| This tutorial is recorded using,

macOS Catalina version 10.15.7

Google chrome version 101.0.49

|-
|| '''Slide Number 4'''

'''Pre-requisites'''

'''https://spoken-tutorial.org'''

|| To follow this tutorial,

Learners should be familiar with topics in basic mathematics.

Please use the link below to access the tutorials on '''PhET simulations'''.

|-
|| '''Slide Number 5'''

'''Link for PhET simulation'''

'''https://phet.colorado.edu/en/simulations/number-line-integers'''
|| Please use the given link to download the '''PhET''' '''simulation'''.
|-
|| '''Slide Number 6'''

'''PhET simulations'''

|| In this tutorial, we will use the '''Number Line: Integers''' '''PhET simulation'''.

|-
|| Point to the simulation in the Downloads folder

'''Number Line: Integers simulation'''

|| I have already downloaded the '''simulation''' to my '''Downloads''' folder.
|-
|| Double click on the '''number-line-integers_en.html''' file
|| To open the simulation, double click on the '''number-line-integers_en.html''' file.

The file will open in your default browser.

|-
|| Point to the simulation interface
|| This is the interface of the '''Number Line: Integers''' simulation.
|-
|| Point to each screen
|| The interface has two screens, '''Explore''' and '''Generic'''

|-
|| Click on '''Explore''' screen
|| Click on the '''Explore''' screen.
|-
|| Point to the number line.
|| The screen has a vertical '''number line ''' to depict the elevation of objects.
|-
|| Point to the '''Objects''' box.
|| This is the '''Objects '''box at the bottom of the screen. We can drag and place objects on the number line.

|-
|| Point to the different scenarios.
|| We can view this '''simulation''' in different scenarios.

The first one is the comparison of elevations of a person, a bird and a fish.

The second is the comparison of two bank account balances.

The last is the comparison of temperatures of different locations.

|-
|| Point to the smaller '''reset''' button.
|| The smaller '''reset''' button resets the current scenario.
|-
|| Point to the information check boxes.
|| On the top right, we have the following check boxes.

'''Number Line''', '''Labels''', and ''' Absolute Value'''

We can use these check boxes to show and hide the details.

|-
|| Point to the '''Comparison Statement ''' on the top centre of the screen
|| At the top, is the '''comparison statement'''.

It can be minimised.

We can again maximise it when required.
|-
|| Point to the '''reset''' button
|| The '''reset''' button resets the simulation.
|-
|| Point to the '''Objects''' box
|| Let us put the objects inside the scenario.

We can place them at any point on the line.

Their position from the sea level is represented on the number line.

|-
|| Check the '''Absolute Value''' check box
|| Let us check the '''Absolute value''' check box.

It shows us the distance as an absolute value.

It also tells us the direction of the three objects.

|-
|| Point to the '''Person'''.
|| The person is placed 62 metres above sea level.

This is represented as 62 metres on the number line.
|-
|| Point to the '''Bird'''.
|| The bird is placed 30 metres above sea level.

This is represented as 30 metres on the number line.
|-
|| Point to the '''Fish'''.
|| The fish is placed 45 metres below sea level.

This is represented as -45 metres on the number line.
|-
|| Point to the '''Comparison Statement'''.
|| See the comparison statement at the top.

-45 is less than 30 which is less than 62.

Using these arrows, we can view the comparison in ascending or descending order.

|-
|| Point to the sea level on the screen.
|| Note that an object can also be placed on the surface of the sea.

|-
|| Drag the '''Bird''' down to the sea level.
|| Let us drag the bird down to sea level.
|-
|| Point to the number line.
|| In this case, it is represented as 0 on the number line.

|-
|| Click on the second scenario.
|| Let us select the second scenario.

|-
|| Point to the number line.
|| This number line represents bank account balance.

|-
|| Point to the buttons on the left of the number line.
|| Using these buttons we can add or remove money from the account.

We can also drag the objects on the number line.

|-
|| Point to the toggle switch.
|| The toggle switch on the right, allows us to represent one or two accounts.

|-
|| Click the add money button for object 1.
|| Let us deposit 5 dollars in the first bank account.

The object gets bigger and moves 5 places to the right on the number line.

|-
|| Click the remove money button for object 2
|| Let us withdraw 3 dollars from the second bank account.

The object gets smaller and moves 3 places to the left on the number line.

|-
|| '''Slide number 7'''

'''Transactions table'''
|| Now, let us perform the following transactions in the simulation.

They represent weekly activities of two different people.

(Note: See table 1)

|-
|| Point to the number line.
|| This is the result of the transactions.
|-
|| Check the '''Absolute Value''' check box.
|| Now check the '''Absolute Value''' check box.
|-
|| Point to the bank account 1.
|| Bank account 1 has a balance of 30 dollars.

It has moved further right from the origin.

Its relative position from the origin is plus 30.

|-
|| Point to the bank account 1.
|| Bank account 2 is in debt of 17 dollars.

It has moved further left from the origin.

Its relative position from the origin is -17.
|-
|| Point to the number line.
|| The total difference between the two accounts is 30-(-17) which is 47 dollars.

This is represented on the number line.

|-
|| Point to the comparison statement.

Point to the two bank accounts.
|| The comparison statement shows that -17 is less than 30.

Users can change the values in the two bank accounts and check the differences.

|-
|| Click on the third scenario.
|| Let us select the third scenario.

|-
|| Point to the number line.
|| This vertical number line represents the temperature of different locations.

We can view this in the ''''Fahrenheit''' or '''Celsius''' scale.

The ''''Fahrenheit''' scale is chosen by default.

|-
|| Click on ℃ radio button.
| Let us choose the '''Celsius''' scale.
|-
|| Point to the drop down list.
|| We can select the months of the year from the drop down on the right.

Temperatures on the map will vary accordingly.

January is chosen by default.

|-
|| Point to the '''Objects''' box.
|| Let us put the thermometers at different locations on the map.
|-
|| Check the '''Absolute Value''' checkbox.
|| Let us check the '''Absolute Value''' checkbox.

It will show us the temperature purely in terms of its magnitude.

|-
|| Point to the '''Location A'''.
|| The temperature of location A is 24 degrees above 0.

This is represented as 24 degrees Celsius on the number line.

|-
|| Point to the '''Location B'''.
|| The temperature of location B is 19 degrees above 0.

This is represented as 19 degrees Celsius on the number line.

|-
|| Point to the '''Location C'''.
|| The temperature of location C is 33 degrees below 0.

This is represented as -33 degrees Celsius on the number line.

|-
|| Point to the '''Comparison Statement'''.
|| This is also reflected in the comparison statement.

-33 is less than 19 which is less than 24.

|-
|| Point to the number line.
|| Observe that temperatures above 0 degrees are represented as positive integers.

And temperatures below 0 degrees are represented as negative integers.

|-
|| '''Slide number 8'''

'''Temperature Comparison table'''
|| This table represents the temperatures of 3 different locations over 5 months.

(Note: See table 2)

It indicates the change in the climatic conditions in various parts of the world.

|-
|| Click on '''Generic''' screen.
|| Now click on the '''Generic''' screen.

The Generic screen has some new tools.

|-
|| Point to the '''Scale'''.
|| From this list, we can select the '''scale''' of the number line.

-10 to 10 is chosen by default.

|-
|| Point to the number line representations.
|| We can choose between a '''horizontal''' or '''vertical ''' representation of the number line.

'''Horizontal''' is chosen by default.

|-
|| Point to top right check boxes.
|| On the top right, we have the following check boxes.

'''Labels''', '''Tick Marks''', '''Opposite''', and '''Absolute Value'''.

We can use these check boxes to show and hide the details.

|-
|| Point to the number line
|| Explore the '''Generic''' screen to understand the number line concepts generally.

|-
||
|| With this, we have come to the end of this tutorial. Let us summarise.
|-
|| '''Slide number 9'''
