    2nd Grade Teacher Shares Ideas for Mystery Class

    This 2nd grade teacher shares ideas about calculating photoperiod with
    her students. She offers to share the worksheets she's created. (See below.)

    My second graders and I found that computing the photoperiod time was
    difficult and complicated for them with their current level of skill.
    But I was determined to make this a successful experience and use of the
    Internet, so I devised a worksheet that helps the students to convert
    the military time to standard time and then to tally the hours and
    convert additional minutes to hours as needed.

    I also ended up designing a worksheet to help them decide what their number
    of minutes in the photoperiod time means in fractions so that they can
    represent the time on the graph that Journey North provided. The whole
    process is time consuming but when I use the additional help I receive
    when my two University of Mass students are with me, the kids are
    catching on to some pretty sophisticated math processes and are becoming
    more familiar with calculators.

    I'm not sure how I could send this across the Net but if anyone wasnts some
    help I could fax them or send them out by regular mail.
