    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
    together.
    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
    problem-solving abilities.
    I loved the course and I know that the information I have gained from it
    will be useful in my future teaching endeavors.
