NCERT Class 6 Maths Chapter 4 Data Handling and Presentation: what it teaches

Your child collects and organises data with tally marks, draws pictographs with a key and bar graphs with a sensible scale, and thinks about how to present data clearly and honestly.

Why it matters later. Presenting data honestly is needed for statistics in later classes and in science projects.

Start the scale at 0 and label both axes.

You need

  • squared paper
  • coloured pencils
  • a question to survey 15 or more people

Tonight’s 20 minutes

  1. Survey: “Which is your favourite fruit?” Record with tallies.
  2. Make a frequency table.
  3. Draw a pictograph where one symbol stands for 2 people.
  4. Draw a bar graph with a scale of 1 unit = 2 people and label both axes.

Words to use

  • data
  • tally
  • frequency
  • pictograph
  • key
  • bar graph
  • scale
  • axis

Watch for

  • Bar graph axes not starting at zero. Start the scale at 0 so bars compare fairly.
  • Pictograph halves ignored. If one symbol = 2, show 1 as half a symbol.

What it sounds like at home

A short example of the conversation. Your words will differ; the questions are what matter.

YouOne symbol means 4 people. How many for 3½ symbols?

Your child12 plus 2 is 14.

YouWhy start the bar graph at 0?

Your childOtherwise bars look more different than they are.

YouWhich is most popular?

Your childMango.

A game for this week: Survey challenge

  1. Choose a question with one answer per person.
  2. Survey 15 people.
  3. Make a table, pictograph and bar graph.
  4. Present three facts and one surprise.

A 5-day plan, 20 minutes a day

  1. Day 1Collect data with tallies.
  2. Day 2Frequency table.
  3. Day 3Pictograph with a key.
  4. Day 4Bar graph with a scale.
  5. Day 5Survey challenge presentation.

Why start a bar graph scale at 0?

So bar lengths compare fairly.

Ready for the next chapter when your child…

  • Organises data into tables.
  • Draws pictographs and bar graphs with scales.
  • Reads and explains graphs.

Questions parents ask

What is the difference between a pictograph and a bar graph?

A pictograph uses symbols with a key; a bar graph uses bars against a scale.

How do I choose a scale?

Pick steps that fit the biggest value on the paper, like 1 unit = 2 or 5.

What are artistic considerations in graphs?

Clear labels, colours and layout so data is easy and honest to read.
