What this lesson shows
Pies eaten by 10 contestants: the mean, median, mode, and range.
The worked example
The lesson works this one step by step: Pies eaten by each contestant: 1, 2, 2, 2, 3, 3, 5, 6, 8, 8. Then your kid tries one like it on paper.
The steps
- Mode: tallest stack
- Median: the middle
- Range and mean
Helping at home
The mode is the tallest stack. The median is where the Xs counted in from both ends meet. The range is the greatest minus the least. The mean adds every X and shares the total out.
If your kid gets stuck
Mode, median, range, then mean.
