We divide the students into groups of four and assign a role to each member: reader, accountant, scribe and draughtsman.
The group starts by reading four lines of a story and makes a prediction of what vowel they think will be the most frequent.
Then, they count the five vowels and construct a bar chart that represents the frequency with which the different vowels appear. Next, we reflect together on how we have represented the bar chart: vertical or horizontal, and why; on how we have compiled the information: if we have used a table to record the frequencies, if we have counted drawing lines …
Finally, we will discuss and reflect whether variability is the same in all the groups and if the result was the expected or not.
