Class 4 Data Handling Worksheet – Bar Graphs, Pictographs & Data Interpretation

Data handling worksheet for Class 4 with tally marks, pictographs, and tables. Includes solved examples and practice questions to help your child collect, organise, and present data clearly.

What is Data Handling?

Data means information or numbers that we collect about the world around us. Data Handling is the process of organising this information so it becomes easy to count, compare, and understand.

Ways to Show Data

Tally Marks: A quick way to count things. We draw 4 vertical lines and cross them with a 5th diagonal line to make a group of 5. This makes counting large numbers faster and less error-prone.

Pictographs: Pictures or symbols used to represent data. In Class 4, each picture stands for exactly 1 item, making them straightforward to read and draw.

Tables: Information organised neatly into rows and columns so we can read it at a glance.

Solved Example

A pictograph shows toys in a shop. Cars have 5 symbols and Balls have 3 symbols. Each symbol represents 1 toy.

How to Read This

Count the number of symbols next to each item. Cars have 5 symbols, so there are 5 cars. Balls have 3 symbols, so there are 3 balls. Cars have more toys than balls.

Practice Problems

• Count a set of tally marks and write the total number. → Reading Tally Marks
• Look at animals in a picture and count how many of each type there are. → Counting and Sorting
• A pictograph shows ice creams sold on Monday and Tuesday. On which day were more sold? → Comparing with Pictographs
• Count mixed fruits from a picture and organise them into a table with tally marks. → Building a Tally Chart
• A class has 6 dogs, 4 cats, and 3 birds as pets. Which pet do most students have? Draw a pictograph. → Creating a Pictograph
• Count two types of balls from a picture, compare them, and show each using tally marks. → Counting, Comparing, and Recording

Scoring Guide

• 25–30 marks: Superstar! You are amazing at data handling. Keep up the great work.
• 18–24 marks: Great Job! Practice making more tally marks and pictographs.
• 10–17 marks: Good Try! Practice counting tally marks every day. You can do it.
• 0–9 marks: Keep Going! Practice tally marks and counting. Ask your teacher for help.

Tips and Common Mistakes

Remember that a crossed group of tally marks equals 5, not 4. This is the most common mistake at this stage.

Count slowly and carefully. Rushing leads to missed items, especially when sorting mixed objects.

Always check every symbol in a pictograph before writing your answer. Missing even one changes the total.

Practice daily by counting real things around you — toys, books, pencils — and recording them using tally marks.

Write your answers clearly. Skipping the final step of writing down the number is an easy mark to lose.
