Data Through Pictures 5 Maths Chapter 15 CBSE Notes 2025-26

The chapter “Data Through Pictures” from Class 5 Maths helps students understand how information can be shown visually using tables, icons, pictographs, and bar graphs. It uses relatable situations such as keeping track of TV watching habits, observing playground items, counting vehicles, and daily routines to explain basic data concepts. The chapter encourages children to investigate, record, and compare data from their own environment.

How to Collect and Represent Data Children can collect information by asking questions or observing events around them. For example, Samaira and Kabir acted like reporters and asked their friends how many hours they spend watching TV daily. The information was organised in a table with two columns: 'No. of Hours Spent Watching TV' and 'No. of Children.' Tables make it easier to compare and answer questions about the data collected.

Students are asked further questions such as: How many children watch TV for more than half an hour? How many watch for less than two hours? These types of questions help them explore and interpret the recorded data.

Pictographs: Using Pictures for Data When there is a lot of information to record, pictographs offer a fun alternative. For example, in a shop, Joseph Uncle uses pictographs to count toys, board games, and sports items. Instead of drawing each item, students can use symbols: one toy icon represents five toys, helping to count faster. The use of a scale (such as 1 icon for 5 toys) keeps the pictograph simple and neat for large numbers.

• 🎲 = 5 toys
• 🎲 = 5 board games
• 🏏 = 5 sports items

Students can try using different scales, such as one icon for 10 items, depending on how many things they need to record. The pictograph method makes data easy to understand and compare at a glance.

Observing and Comparing with Pictographs The chapter gives another example where Deepti counts the number of two-wheelers on the road. By using 🛵 to stand for 3 vehicles, she records the data for three days and then compares which day had the highest or lowest numbers. Questions are provided to help students practise comparing days and total counts.

Understanding Bar Graphs To show data where actual numbers or direct comparison is important, bar graphs are useful. Bar graphs use vertical or horizontal bars of different lengths to represent data. Sheela, for instance, records her daily routine in a bar graph, showing how she divides her time between sleeping, school, studying, eating, playing, and other activities. This visual representation helps students quickly identify which activity takes the most or least time.

• Bar graphs have activities on one axis and the number of hours on the other.
• Longer bars mean more time spent; shorter bars mean less time spent.

Students are encouraged to make their own bar graphs based on how they spend their time in 24 hours and to discuss which routine seems more balanced.

Measuring and Recording in Daily Life Children are guided to use data collection even in everyday activities, like measuring the length of their index fingers using strips of paper. After measuring, the strips can be pasted on a bar graph to compare whose finger is longest or shortest. This activity makes measuring and comparison lively and personal.

Awareness Themes: Food Wastage The lesson also brings out social responsibility by introducing the topic of food wastage at Rani’s school. Data is shown as a bar graph depicting the amount of each food item wasted in the canteen across different days. Students think about the impact of wastage—if 1 kg of food can feed 3 children, how many children could have been fed instead?

Students are prompted to discuss practical ways to reduce food wastage, such as taking only as much food as they can eat or reutilising leftovers.

Picture Observation Activities The chapter concludes with activities where students observe images and decide whether statements are true or false. For example: “All girls are wearing glasses”—students must look at the picture and mark TRUE or FALSE. Such observation questions develop careful analysis skills, attention to detail, and the habit of verifying data visually.

Summary Tables and Tools The endnotes of the chapter include handy references such as the fractions kit (where unit fractions like 1/2, 1/3, 1/4, etc. are tabulated) and number tokens. These are tools for students to cut out and practise, supporting basic arithmetic and fraction sense in fun, tactile ways. Instructions for nets of solid shapes (Icosahedron and Dodecahedron) are also included to reinforce understanding of 3D shapes and nets.

Through engaging examples and hands-on activities, “Data Through Pictures” helps students build skills for organising, visualising, and analysing information, which are foundational for mathematics and everyday decision-making.
