Data means raw facts and figures — like marks, names, photos or sounds. On its own a pile
of data is messy. But once we organise it and turn it into a neat table or a colourful chart,
it becomes useful information that helps us make good decisions. Let's play with the 5 types of data,
build a bar chart, and draw a pictogram! 🎉
Playground 1 · Sort the data (5 types) 🗂️
Every piece of data has a type. Tap an item, then drop it
into the right bucket. You get a ✅ or ❌ each time — collect a perfect score!
1️⃣ Pick an item
2️⃣ Drop it in the right bucket
Score: 0 /
12
🔎 The 5 types of data🔢 Numerical = numbers you count or measure (marks, age, temperature).
📝 Text = letters and words (your name, address, a message).
🖼️ Image = pictures (photos, drawings, emojis).
🎬 Video = moving pictures (movies, CCTV, an online class).
🔊 Sound = audio (a song, a voice message, the school bell). 🔔
Playground 2 · Bar chart — which sold most? 🍋
Riya ran a stall last week. A bar chart compares categories —
the tallest bar sold the most. Tap − / + to change the weekly totals and watch the bars
and the winner 🏆 update.
📊 How to read a bar chart
The bottom line (the X-axis) tells you the categories — here, the things Riya sold. The side line
(the Y-axis) tells you how many were sold. A taller bar means a bigger number, so the tallest
bar is the best-seller. Always read the title and the axis labels first!
Playground 3 · Pictogram builder 🌳
The Eco-Club counted trees planted by each class. A pictogram
uses a symbol to stand for a number — that's the KEY. Switch the key and watch the rows of 🌳
recount themselves!

🧠 From raw data to good decisions
Data is just raw facts. First we COLLECT it (from people, books, the internet, or instruments).
Then we ORGANISE it — classify (group similar data) → structure (folders & tables) →
label (clear names) → store (save it safely). Finally we REPRESENT it: tables for
exact values, bar charts to compare, and pictograms for a fun picture-count. Now we can understand
it and make good decisions! ✨
