Perhaps they will benefit from an example of what an average is, prior
to a statement of what the concept 'is'. I can imagine a teacher
explaining to a class that they could put all their lunch moneys into a
pile & then redistribute it equally so that each student has the same
amount.... <Caution: if you are a teacher, be aware of the possibility
of some involved parent taking umbrage at "income redistribution"!>

But wouldn't the more astute little tykes say that teachers' pets get
the higher marks & the trouble-makers lower?

>Start with the average of two scores, then 3, 4 etc. Ask them why it
is useful in the end to give an average score rather than a list of 30
scores.

Students may not see the need for a single number, rather than two or
five. The class might consider a student who has written 5 math tests.
He can either tell his poor old man: "my average on the last 5 math
tests was 64% - or - he could say "I got 80% on the 1st four and 0% on
yesterday's."
Maybe his mom is trying to quit smoking: "I have had 7 cigarettes in the
last week: 1 day on an average" vs "I had 7 cigs a week ago but none since"

So: Students: when would a single number be good enough? monthly class
absenteeism? maybe to compare all the grade 6 classes. Or tardiness?

These are the 'mathy' topics that should indeed be mastered. But if
there is some context (why we might want to use averages) I would hope
the success ratio might be higher, on average;)

Do I sniff a conspiracy? & if so, why?
