Finding the mode
Identify the mode of a data set shown in a tally, pictograph, concrete graph, bar graph, line plot or table: every value or category that occurs most often, so a data set can have one mode or several tied modes; use the convention that there is no mode when every value occurs exactly once; explain what the mode tells about the data; and compare the modes of two data sets
Lesson
Set out your lesson
“Finding the mode 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 Finding the mode, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Finding the mode, not mastery.

Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
Finding the mode 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
- Point to the mode on a pictograph or bar graph of favourite fruits and on a line plot of shoe sizes, and say it is the most common response
- Name every mode when two or more categories tie for the most (e.g. apples, bananas and grapes each chosen 6 times), and say there is no mode when every value occurs exactly once
- Find the modes of two classes' favourite-fruit tallies and say whether the modes are the same, even when the counts in each category are different
“After a family vote on pizza toppings, can your child tell you which topping was chosen most often (the mode) and what it means if several toppings tie?”
