Pre-K students can figure the 'mean' if you talk about balancing. Suppose
you have a bar graph with 5 categories. Category 1 has 6 items; category 2
has 4 items; category 3 has 7 items; category 4 has 4 items; and category 5
has 4 items. All 5 bars have at least 4 items. Category 1 has 2 'extra'
and category 3 has 3 'extra' -- if I distribute those 5 'extra' to all 5
bars, then each bar will have a mean of 5.
I did this with some Pre-K students today. Actually they are pre-pre-K -
they'll be in Pre-K when school starts. They all did fine.
Hope this works for you.

Subject: [Channel-talkdata] Session #10 Homework Problem H3
This year I taught in a integrated preschool classroom and we recorded our
daily weather each morning as a large group. I mainly focused on this
activity for the 1-1 correspondence for my 4-5 year old students; but, after
taking the course I realize how much further I can take this routine
activity. I have been working on a way for the children to record the data
on their own weather graphs and continue to their basic math skills with
additional questioning that would be geared toward the average type of
weather for the month (mean), the median, and the mode. We already do the
mode using the terms the type of weather that occurred the most during the
month. Of course, my students would not be able to figure out what the mean
would be, but I could ask them to predict using their graphs what they
believe it to be and then basically figure it out in front of them for
exposure to addition and division. We could also easily find the median
This weather graph activity is actually my work in progress for my project
because it would be used daily and it would be beneficial to their
I loved the course and I know that the information I have gained from it
will be useful in my future teaching endeavors.
