Week 20 - Sorting, Filtering & Functions (Applied Together)

 

CLASS OBJECTIVE

Apply sorting, filtering, and basic functions (SUMA, PROMEDIO, MIN, MAX, COUNT, COUNTA and COUNTBLANK) together to organize and analyze simple data efficiently in a spreadsheet.

⸻

🗓 

CLASS AGENDA

💬 Introduction

“Imagine you have a list of grades, expenses, or attendance.

What if you could organize it, see only what you need, and calculate everything automatically?”

---

1️⃣ Short Review

Students recall:

• What sorting does (change order).

• What filtering does (show specific data).

• What functions do (calculate or count automatically).

Teacher reminds:

📌 Spreadsheets are powerful when you combine tools.

---

2️⃣ Explanation: Working With Data Step by Step

Teacher explains the correct order:

1. Organize data (clear table with headers).

2. Sort data (A–Z, highest to lowest).

3. Filter data (show only what you need).

4. Apply functions to analyze results.

Simple examples:

• Sort grades from highest to lowest.

• Filter only “Passed” students.

• Use PROMEDIO() to find average grade.

---

3️⃣ Demonstration

Teacher shows a simple table (grades, attendance, or expenses) and demonstrates:

• Turning filters on and off.

• Sorting numeric and text data.

• Applying functions after filtering.

• How results change when data changes.

Students observe how one table gives many answers.

---

4️⃣ Activity – “From Data to Answers”

Students will organize a table, apply sorting and filters, and use functions to answer simple questions.

---

5️⃣  Take notes in your notebook.

📓  NOTES IN YOUR NOTEBOOK

Answer these questions:

1. Why is it important to sort data before analyzing it?

2. What is the advantage of filtering information?

3. Which function do you use to calculate an average?

Week 19: Counting Functions – COUNT(), COUNTA(), COUNTBLANK()

CLASS OBJECTIVE

Learn how to use basic counting functions in a spreadsheet — COUNT(), COUNTA(), and COUNTBLANK() — in order to identify how many cells contain numbers, text, or are empty.

⸻

🗓  CLASS AGENDA

💬 Introduction

“Imagine you have a list of assignments and you want to know how many you finished and how many are missing.

Instead of counting by hand, a spreadsheet can count for you.”

---

1️⃣ Short Review

Students recall:

• What a range is (A1:A10)

• What a function is (name + parentheses + arguments)

• Basic data types: text, number, blank

---

2️⃣ Explanation: What Are Counting Functions?

Teacher explains:

Counting functions count cells automatically depending on what is inside them.

💡 Simple definition for students:

“Counting functions help the spreadsheet tell you how many things you have.”

---

3️⃣ Explanation of Each Function

Teacher shows simple examples for each one.

---

🔹 COUNT() – Counts only numbers

=COUNT(A1:A10)

Example:

Count how many grades (numbers) are written.

---

🔹 COUNTA() – Counts all non-empty cells

=COUNTA(A1:A10)

Counts:

• Numbers

• Text

Example:

Count how many students wrote something.

---

🔹 COUNTBLANK() – Counts empty cells

=COUNTBLANK(A1:A10)

Example:

Check how many assignments are missing.

---

Teacher demonstrates using simple datasets such as:

• Homework: Completed / Blank

• Attendance: Name / Empty cell

• Grades list

---

4️⃣ Demonstration

Teacher opens a spreadsheet and shows step by step:

• How to write each function

• How to select ranges correctly

• How changing data updates the result instantly

Students observe how each function works with real examples.

---

5️⃣ Activity – “Counting My Data”

Students will work with a small table (attendance, homework, preferences) and apply all three counting functions.

---

6️⃣ Take notes in your notebook.

---

📓  NOTES IN YOUR NOTEBOOK

Answer these questions:

1. What does the COUNT() function count, and write an example?

2. When is COUNTA() more useful than COUNT(), and write an example?

3. What does COUNTBLANK() help you identify and write an example?

4. Why are counting functions useful for students?

⸻

📌 KEYWORDS

• COUNT(): Counts only numbers

• COUNTA(): Counts non-empty cells

• COUNTBLANK(): Counts empty cells

• Range: A group of cells (A1:A10)

• Data type: Text, number, or blank

Week 15,16,17,18 - Introduction to Functions (SUM, MIN, MAX, AVERAGE)

CLASS OBJECTIVE

Learn what a function is, understand its structure (name + parentheses + arguments), and use basic spreadsheet functions such as SUM(), MIN(), MAX(), and AVERAGE() to analyze simple data.

⸻

🗓 

CLASS AGENDA

💬 Introduction

“Have you ever wished your calculator could find the largest number or the average of your grades automatically?

Spreadsheets can do that with just one function.”

---

1️⃣ Short Review

Students recall:

• What is a cell, row, and column

• What is a formula (=)

• Basic arithmetic operators

---

2️⃣ Explanation: What Is a Function?

Teacher explains:

A function is a built-in operation in the spreadsheet that performs a calculation automatically.

📌 Structure of a function

=FUNCTION_NAME(argument1, argument2, …)

Examples of arguments:

• A single cell → A1

• A range → A1:A5

• Several ranges → A1:A3, C1:C3

💡 Simple definition for students:

“A function is like a smart formula that does the work for you.”

---

3️⃣ Explanation of Basic Functions

🔹 SUM() – Add many numbers quickly

=SUM(A1:A5)

🔹 MIN() – Find the smallest number

=MIN(B1:B10)

🔹 MAX() – Find the largest number

=MAX(B1:B10)

🔹 AVERAGE() – Find the average

=AVERAGE(C1:C5)

The teacher uses a small example table such as grades or prices.

---

4️⃣ Demonstration

Teacher opens a spreadsheet and shows step by step:

• How to select a range

• How to insert functions using the fx bar

• How the function updates when numbers change

• How to read the result correctly

Students observe how SUM, MIN, MAX, AVERAGE work in real time.

---

5️⃣ Activity – “My First Functions Table”

 

(Mention only)

Students will create a small data table (e.g., 5 grades, 5 prices, 5 scores) and apply each function.

---

6️⃣ Homework

HOMEWORK

No homework this week.

Week 14: Sorting & Filtering Data

 CLASS OBJECTIVE

Learn how to organize information in a spreadsheet by using basic sorting (A–Z, Z–A) and filtering tools in order to quickly find and understand data.

⸻

🗓 CLASS AGENDA

💬 Introduction

“Imagine you have a long list of students, scores, or expenses. Would you look line by line to find what you need?
Sorting and filtering make this MUCH easier.”

---

1️⃣ Short Review

Students recall:

• What types of data exist (text, number, date, formula).
  

• What a table looks like (rows + columns).
  

• Why organized information is easier to understand.
  
  

---

2️⃣ Explanation: Sorting vs Filtering

🔠 Sorting (Ordenar)

Changes the order of data.
Examples:

• A → Z (ABC order)
  
  

• Z → A
  
  

• Smallest → Largest
  
  

• Largest → Smallest
  
  

📌 Sorting rearranges the whole list.

---

🔍 Filtering (Filtrar)

Shows only the information you want to see.
Examples:

• Show only students with grade above 80
  

• Show only “Completed” tasks
  

• Show only the month of February
  
  

📌 Filtering does NOT delete anything — it just hides what you don’t need for the moment.

---

3️⃣ Demonstration

Teacher shows:

• How to select the header row
  

• How to click the filter icon (funnel symbol)
  

• How to sort A→Z and Z→A
  

• How to filter by:
  
  

• Text
  

• Number
  

• Conditions (greater than, equals…)
  

• Checkboxes
  
  

Students observe how the table changes instantly.

---

4️⃣ Activity – “Order My List!” (Mention only)

Students will practice sorting lists (names, scores, favorites).
Then they will apply filters to hide and show specific information.

---

5️⃣ Take notes in your notebook.
