Choosing displays for a purpose
Compare different displays of the same data set (for example a tally chart and a picture graph, or a table and a bar graph), describe what is common and what each display makes easy to see, and choose the display that best suits a question or purpose
Lesson
Set out your lesson
“Choosing displays for a purpose means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Tally sheet or simple bar sketch
- A short set of category counts
Extra for the adult
Worked example. Cats 4, dogs 2 — cats have more. The tally and comparison are the proof.
Optional challenge. For Choosing displays for a purpose, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Choosing displays for a purpose, not mastery.

Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
Choosing displays for a purpose means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.
Materials: Tally sheet or simple bar sketch; A short set of category counts. Adult tallies one category and sketches a bar. Child tallies three categories and answers one comparison question. Done: three tallies plus one correct comparison. Stop after the fresh check; keep optional challenge for another day.

Where a teacher solution is present, it is on the same page as the student task; this check did not find a separate locked student view. An adult can use the student view section and should not read a solution aloud. Advertising was not observed in the fetched HTML text; that is not a browser, device, or ad-free guarantee. This is a paper or discussion task, not an automatically marked interactive game. Opening the link does not save practice or assess mastery. Diagrams on the page use missing or filename-only alt text, so they are not an accessible image equivalent. Accessibility still depends on an adult describing the picture.

Check understanding
- Show the same pet survey as a tally chart and as a picture graph and say what is the same in both and what each makes easier to see
- Answer the same question (e.g. 'How many chose dogs?') from two different displays of the same data and say which display made it quicker
- Choose a table to read an exact count and a bar graph to compare categories at a glance for a given purpose, and explain the choice
“If your child sees the same survey results shown two ways — say a tally chart and a bar graph — can they say what both show, which one makes the favourite easier to spot, and when a table would be the better choice?”
