LIBREOFFICE CALC

4 ESO - CLIL

Before beginning, download from Moodle your personal Calc template. You must make all these activities using this file. Your personalized file is a spreadsheet, containing 16 sheets, one for each exercise in this unit.

Dont' use, modify or delete the first three sheets, (hoja1, hoja2, hoja3). These sheets contain information used to make sure the file is used properly.

EXERCISE 1. PAÍSES

• Start LibreOffice.org Calc selecting the menu Aplicaciones→Libreoffice→ Hoja de cálculo. Open your personal template.

The gridded space is known as the  Work area. Each rectangle in the grid is a cell (celda en español), and can be used to enter data. The active cell is marked by thicker borders and is the only one in which is possible to edit data.

• Every column is named with a letter (A, B, C,..., AA, AB, AC,....)

• Every row is numbered(1, 2, 3, 4,...).

• Every cell is named using its column letter and row number. For example, in the image above the active cell is B2

• Open the sheet 1.Países

• Click in the cell B2 to turn it into the active cell. Write the text Francia into it . Notice that as you write in the cell the text is also shown in the formula bar (look at the image below). The text can also be edited in the formula bar

• Write Italia into the cell B3 ,

• Write 1 in the cell A2.

• Write 2 in the cell A3

• Select both cells. Notice that a little black square appears in the selection lower right corner. This square is called the Autofill Handle (control de relleno). Click on it and drag it down to the cell A11. This action will fill all the cells in the selected range with a sequence of numbers 1,2,3,4…. 10 as shown in the images below

• We are going to create a table for a person who is planning a number of trips throughout Europe. The traveler is going to visit a different country  the first day every month, starting with January.

• Select D2 and write 01/01/2017. Then select D3 and write 01/02/2017

• Select D2:D3 (this means from D2 to D3), and click in the autofill handle (remember, the little black square on the cell bottom right corner) and drag it down to D11

Result expected:

We can enter in a cell different data types, for example, so far you have entered Text, numbers, and dates. In Calc there are other data types like booleand data:

• Select E2. Our traveller will write in this column Sí /No. depending on wheter he will travel by plane . The answer can only be Sí /No. This type of data is called Boolean data and represents information with only two possible values: yes/no, true/false, 1/0.
• Write No at the column E for España, Francia and Portugal, and for the other countries

One data type, can also be represented in different ways. For instance, numbers, can be represented as regular numbers (33,4), but also as money (33,40€), as percentage (33,4%), and in scientific notation

•  In the column F enter random (aleatorio) numbers between 1000 and 4000, with two decimals.
• Select the cells F2:F11 and apply money format to them clicking on the money button (shown below) in the toolbar

Another way of representing numbers is as percentages. In the column G, we are going to enter the VAT ( IVA in spanish) of each country.

• Starting on G2, enter random values between 0,10 and 0,25.

• Select G2:G11 and click on the % button to give this numbers a percentage format. Notice that in order to write percentages you must write a number between 0 to 1. That is: 0,12 becomes 12%. Take care, the typical mistake here is to  write 12 in the cell, which will become 1200% instead of 12%

The numbers can also be represented with a greater or lower amount of decimals using the buttons añadir y eliminar decimales

It's pointless (sin sentido, innecesario) to allow decimals on the column G, in the VAT is a whole number with no decimals in all european countries. Delete these decimals using the buttons añadir y eliminar decimales

If we apply the IVA (column G) to the trip price without VAT (column F), we will get the real price of the trip. Create in the column H a formula to work it out (calcularlo)

• Select the cell H2

• Place the cursor in the formula bar and write the formula =F2+(F2*G2). Important every formula must start with the  = character.

Finally, spread (extender) the formula from H2 to H11 dragging (arrastrar) the black square down.

• Save a back up copy with the name ejercicio1

EXERCISE 2. CAPITALS

Open your template and select the sheet 2.capitales. The goal in this exercise is to carry out a little test of Geography. The user must enter in the column C the name of the capital city of the country in the same row in the column B, and the sheet will assess (evaluar) if the answer was correct.

• Click in the cell D2 and write this formula      =Si(C2=”PARÍS”;“CORRECTO”; “FALSO”)        Explanation: Si(), is a function, with the following syntax: SI(expression;value_if_true;value_if_false)

Expression is a condition which can be true or false. If expression is true, value_if_true is stored in the cell, otherwise, the value stored is value_if_false

In the row 2 (Francia), the condtional expression which must be true is C2=”PARÍS”. If the user enters PARÍS in C2 the condition is true and as a result the value CORRECTO is written in the cell D2 . In any other case, the written value in D2 will be FALSO

Fill the rest of cells from D3 to D11 with the suitable formulae to asses the user answers in C3 : C11. For example in D3 you should enter =Si(C3=”ROMA”;“CORRECTO”; “FALSO”)

Save a back up copy with the name ejercicio2

EXERCISE 3. DAYS LIVED

In this exercise we will carry out a sheet to work out (calcular) the number of days a person has lived so far,

Open the sheet 3 Dias vividos in your personal template.

In B2 write the sheet title ¿Do you want to know how many days have you lived so far?

Increase the font size and highlight the text using bold letters. The format bar is very similar to the one you learned to use in LibreOffice Writer

Write in A4 Enter your birth date in the highlighted cell

The dates can be entered writing day, month,and year separated by a slash (/), a dash (-), or a dot (.). For example: 17/12/15; 17-12-15 or 17.12.15.

The user must enter his birth date in E4. Format this cell as a date using Formato celdas ->Numero, In the pannel categoria select fecha

Highlight this cell with a thicker line borders using the menu Formato celdas→ Borde .

In G4 we are going to subtract the today's date with the date entered by the user. We will use the function HOY(), (in valencian  AVUI()), which returns today's date.

• Write in G4 =hoy(). (avui() if your LLiurex uses valencian. The result is a number meaning the number of days from 1/1/1900 to today. To turn it into a date, select G4 and click in the button fecha

Select the cell E7 and write the formula =DIAS(G4;E4), which returns the numbers of days went by (pasados, transcurridos) between the dates in G4 (today) and E4 (the user's birdth date)

Select E7 and change the text color to red, and align it to the center using Formatear celdas. Enable the Separador de miles option, in the tab Numeros.

To end up the sheet write some clarifying instructions as shown in the image. Try to translate them to English, (of course)

• Save a backup copy with the name ejercicio3

EXERCISE 4 SUBTRACTION TABLE

Open the exercises template in the sheet 4. Restar. Select a random cell and write =8+7 and press on the key enter. You have just written a mathematical expression using the operator +. There are many other mathematical operators in Calc

+      Suma

-      Resta

*      Producto

/      División

^     Potencia

%    Porcentaje

<      Menor que

>      Mayor que

=      Igual que

<>     Distinto que

<=     Menor o igual

>=     Mayor o igual

Keep in mind that when it comes to (cuando se trata de) write mathematical expressions in Calc, multiplication and division are carried out before addition and subtraction. For example =2+5*4 result is 22, and not 28. You can also use  brackets (paréntesis) to indicate the operators order. For example =(2+5)*4 result is 28 (and not 22)

In this exercise we are going to implement a subtraction table: the user will enter a number in D4 and the table will show the result of subtracting that number to all the numbers between -5 and 5 in the column F

• Write TABLA DE RESTAR, in C1 as the sheet headline.

• Select C1:D1, deploy the contextual menu, and select the option Unir celdas. This options will merge these three cells in a single one. There's also a button unir celdas in the toolbar

 unir celdas

• We are going to write two lines of text, starting in B2. To fit them increase the cell hight, clicking on the border between the files B and C and drag it down, (as shown in the image below)

• In B2 write Escribe en la celda resaltada con borde grueso el número del que se desea obtener la tabla de restar. Then merge the cells B2:F2.

• Select the merged cells and drop down the contextual menu

• Formatea las Celdas→solapa alineación. Select the alignment settings shown in the image below. The goal is to align the text to the center, both vertically and horizontally

• Highlight the cell D4 with an area and border color using the buttons color de fondo, and bordes.

 Botón bordes. Botón color de fondo

• In the column B must appear the number entered by the user in D4. So write =D4 in B6 and then drag down the cell to B16 using the autofill handle, (the little black square)

• This is the result, which is not exactly what we were expecting. We expected to find the D4 value (3) in all the cells in the range B6:B16.

• In a SpreadSheet, by default, the references to cell are relative, that is, the reference is the distance from one cell to the referenced cell. Not to the position of the referenced cell, but the distance in horizontal and vertical cells between the in which the reference is entered and the referenced cell. If you put in B6 the reference =D4, this means that B6 must take the value of the cell placed two columns on the right (B is two columns right from D) and two cells up (6 is two rows down from 4)

• When you drag down B6 to B7, B7 takes the value of the cell placed two rows right two rows up, that is D 5, a cell with no value, instead of D4, as shown in the image below

• The solution is to fix the reference to D4 using the \$ char. Write in B6 the reference =\$D\$4 Putting \$ besides the column (\$D) fix it while dragging it horizontally. Putting \$ besides the Row (\$4) fix it while dragging it vertically. This is called an absolute reference.

• Put in B6 the reference =\$D\$4 , and again drag it down from B6 to B16. The result must be like this one:

• Notice that there are reference mixtes like =\$d4 o =d\$4. The first one sticks on the column D while dragging, the second sticks on the row 4

• In F6 insert the formula =B6-D6 and drag it down until F16. In this case the relative reference system plays in our favor, since we want to subtract the values from B and D in every row

• The subtraction table is done. Try to change the number in D4, all the sheet is redrawn showing the subtraction table of that number

EXERCISE 5 MULTIPLICATION TABLE

Open the sheet 5. Multiplicación in your exercises template.

In the previous exercise you carried out a subtraction table. In this exercise you are going to make a multiplication table, using all the techniques learned in the exercise 4

This time the user will enter the number in the cell G4

• Use the column D to place an absolute reference to G4. (Remember the absolute references uses \$ to fix the reference to a cell)

• Write in F6 the value 0 , and in F7 the value 1, and drag down to F16

• Use the column H to write a formula in which columns F and D are multiplicated

• Save a backup copy called ejercicio5

EXERCISE 6 MENTAL CALCULATION

In this activity the user must demonstrate his skills in mental calculation. The user must solve the equations and write the result in the column I. If the solution is correct a VERDADERO text will be shown in the column J. The message will be FALSO otherwise. In I7 we will place the function =CONTAR.SI(J1:J5;"VERDADERO") (In valencian language the function is COMPTARSI). This function counts the number of cells in the rage J1:J5 containing the text VERDADERO

• Let's get started with the first row. Write in J1 =SI(I1=A1+C1*E1-G1;”VERDADERO”;”FALSO”). Remember, SI will write in J1 VERDADERO if the condition is true,and FALSO otherwise

• Fill in the proper SI formulas in the cells J2,J3,J4, and J5

• In I7 insert the formula: =CONTAR.SI(J1:J5;"VERDADERO") (in valencian language COMPTARSI) this function was explained at the beginning or this exercise

• We also want some user feedback. If the number of true answers is bigger or equal to 3, in J7 must show "PRUEBA SUPERADA". While this goal is not achieved the message in J7 must be "SIGUE CALCULANDO". Write in J7 =SI(I7>=3;"PRUEBA SUPERADA";"SIGUE CALCULANDO")

• Save a backup copy named ejercicio6

EXERCISE 7 DEPARTMENTS

Open the sheet 7, departamentos. We are going to make a table of the expenditure in different departments in a school.

• Set up area and border line colors in the cells as shown in the image below. To set up the area color use the color de fondo, button or the menu option Formato →celdas→tab fondo,

• To set up the border line in a cell and the border color, use the Bordes button, or the menu option Formatea celda→solapa bordes,

• To set up a text color use the button color de texto

• The result must be similar to the one shown below:

The rows 3 to 17 are reserved in order to allow the user to enter the expenditure of the departments ; in the row 18 there will be written the sum of expenditure in any department and in the row 19 you will calculate the percentage of the total expenditure

• To calculate the sum of the expenditure in a department, (that is B3+B4+B5+B6…..+B17), in row 18 write the function SUMA. In B18 write the formula: =suma(B3:B17). Drag right the cell B18 to the G18, (using as before, the little black square)

• In H18 we are going to enter the sum of all departments expenditure, (that is, B18+C18+E18+…...+G18). You must figure out (descubrir la solución) the correct formula taking into account how you solved a very similar problem in the previous paragraph.

• In the row 19 we must work out the percentage of the school expenditure due to each department.

• Select the cells, B19:G19, and set up percentage format with two decimals on them. Use the buttons percentage and the increase/decrease decimals buttons

• Write in B19 the formula = =B18/\$H\$18, and drag it right until G19. In order to get a percentage it isn't necessary to multiply it per 100 since the percentage format makes automatically this multiplication. Notice also that we divide it per \$H\$18, (an absolute reference). If we divided it by H18 (a relative reference), the dragging right wouldn't work properly. It would write C18/I18 in C19, where I18 is an empty cell.

• A last step to end up the sheet. Set up the money format in B3 : G18, and G19. Use the button money. In the image below is shown the expected result

EXERCISE 8 Average Mark

Open the sheet 8 Nota media.

A teacher needs to calculate the average mark got by his students in a trimester. The teacher has assessed 4 task in the trimester and therefore he has 4 mark for each student. But every task must have a different weight in the average mark. For instance:

Mark 1 (N1) 30% de la nota final

Mark 2 (N2) 30%

Mark 3 (N3) 20%

Mark 4 (N4) 20%

The formula we must write in order to calculate the wighted average mark, is::

Let's implement all these data in the sheet:

• In B3:E3 write the student's marks.

• Set up %format in B5:E5 (remember, you can use the % button in the toolbar).

• Enter in B5:E5 the marks weight over the total mark. Important: the sum of all them must be 100.

• Enter in D7 the weighted mark formula shown above. Remember that as you have set percentage format in these cells it is not necessary to divide by 100 in order to get a percentage. That, is the weighted mark is =B3*B5+C3*C5+D3*D5+E3*E5, and is not =(B3*B5+C3*C5+D3*D5+E3*E5)/100, the formula show at the beginning of the exercise

• Format the table as shown in the image above. Remember, you can change the borders colors using formato celda→bordes

• Join the cells B7:C8 and D7:D8. Remember you can use the button unir celdas or the contextual menu option unir celdas.

• Centered vertically and horizontally the data inside the cells using formato celda→alineación, or the align buttons in the toolbar menu (shown in the image below)

EXERCISE 9 UNITS CONVERTER

We are going to make an spreadsheet to convert different units:

• From pounds to kilograms. Kilogramos= Libras *0,4536

• From kilómeters to meters. Metros=Kilómetros *1000

• Join the cells B1:E1 using the option unir celdas (o fusionar celdas) from the contextual menu

• Join the cells BC and DE in the rows 4 to 8 as shown in the image

• Format the sheet with the border and area colors shown in the image

• The formulas to carry out the conversion must be written in D5, D7 y D9. For example, in order to convert Centigrades degrees in Farenheight you should write the formula =(B5*9/5)+32, where B5 is the cell in which the user has entered the centigrade degrees

• Insert n D7 the formula to convert Libras in Kilograms

• Insert n D9 the formula to convert Kilometers en meters

We are going to make a table showing the final results of several student groups in a trimester. Using as input the number of students who passed all the subjects, those who failed in three or less subjects and those who failed in more than 3 subjects.

• Create a table as shown in the image below. Use the borders and area buttons or formatea celda ->borders

In A4, A6, A8, write the number of students in each group. In the cells with orange area enter the number of students who passed all the subjects, those who failed in <3 subjects and those who fail in >3 subject:

• Set percentage format (use button %) in the white cells on the image.

• Write a formula in cell B4, to divide the number of students with 0 failed subjects (B3) by the total number of students (A4)

• In order to drag right from B4 to D4 change in the formula in B4, A4 by \$A\$4

Fill the cells B6:E6 y B8:E8, using the procedure shown in the previous paragraph .

Add the rows needed to calculate the totals for students number and percentage

• In A9 write a formula to add all the students in 1º ESO (that is A8+A6+A4)

• Drag the formula from A9 to D9, to get the total number of students in any category (0 fails, <=3 fails, >3 fails)

• In B10:D10 set up % format and write the formula to calculate the students percentage in each category for all 1º ESO
