Data Handling!
Chapter 18: Pictographs & Simple Charts
Data is not just numbers — it's information about people and things. Pictures can help us understand data quickly and clearly!
What Does the Class Like?
Riya wants to know: "What fruit does our class like most?"
She asks everyone and makes a picture chart!
Milo looks at it and says: "Now I can see the answer right away!"
"That's the power of data!" says Riya. "Pictures tell the story!"
Data is information we collect to answer questions. What questions might we ask?
🔢 Data comes from questions: "What does our class like?" "How many sunny days?" "Which pet is most popular?" Collect answers, count them, show them with pictures!

A pictograph uses pictures to show data. Each picture stands for one item!
👀 To read a pictograph: Count the pictures! Each picture = 1. So 5 apples means 5 children chose apple.
Look at the pictograph and answer the question!
Compare two categories. Count the pictures to find the difference!
Use + and − to add or remove pictures. Create your own pictograph!

Questions & Answers
Reading pictures of data
What is data?
Data is collected information. Favourite fruits in your class, or how many sunny days this week, are both data.
What is a pictograph?
A pictograph shows data using pictures. Each picture stands for a number of things.
Why does one picture sometimes mean more than one?
Because drawing fifty apples takes too long. One apple can stand for five apples. The key tells you the rule.
What is the key?
The key is the small note that says what one picture is worth. Always read the key before reading the graph.
How do I find which has the most?
Look for the longest row of pictures. That is the largest amount without any counting.
Why do we draw graphs at all?
Because a picture shows the answer instantly. A list of numbers takes much longer to understand.
What is a tally mark?
A tally is a quick counting stroke. Four upright strokes with one across means five. Tallies make counting fast and neat.
How can I practise at home?
Count something for a week. Cups of water, birds seen, or minutes read. Draw a pictograph and give it a key.
📊 Readiness signs: Child can count pictures accurately, answer "which is most/least" questions, explain what a pictograph shows, and create simple pictographs from collected data.
