LATITUDE AND LONGITUDE LESSON:

Student assessment work sheets for Latitude and Longitude lesson plan are available at this link:

The individual task consists of completing a work sheet I downloaded onto each laptop.  This will be the first time I try this approach.  I will assure you my administration will enjoy my paperless approach.  Students are instructed to complete directly onto the Word Perfect format work sheet.  It sets the lead for the group task.  Work sheets consist of prior knowledge on latitude and longitude coordinates covered during the week.  The first challenged started here.  All students were able to open the file, but several had difficulties answering on the designated area on the template.  They did not have the Word Perfect knowledge and hesitated when they put answers and the areas became altered on the work sheet.  I was able to assist these students and after reassuring them they proceeded with no other delays.  After completion, they were able to upload it onto the school’s assignment drop box on our website.  Completed work sheets from 2 students are linked to this post.

Reflecting on the first part of the lesson, I believed it went well.  I will continue implementing doing task from uploaded files and then have them upload to the drop box.  I will make this a weekly goal to have students upload assignments and class work onto the drop box.  The individual work part of this lesson is simply a recall and prior latitude and longitude knowledge.  Two focus questions needed to be answered on the work sheet.  Understanding the diversity among my ELLs, I provided the file in English and in Spanish.

  1. Global Positioning System satellites transmit signals to equipment on the ground. GPS receivers passively receive satellite signals; they do not transmit. GPS receivers require an unobstructed view of the sky, so they are used only outdoors and they often do not perform well within forested areas or near tall buildings. GPS operations depend on a very accurate time reference, which is provided by atomic clocks at the U.S. Naval Observatory. Each GPS satellite has atomic clocks on board.(AIRANDSPACE.SI.EDU/GPS.HOTMAIL)

  2. A GPS accuracy depends on the type of receiver. Hand held units are about 10 to 20 meters accurate.

    1. There are some that position objects withing 12 -20 inches, but as always these are very expensive equipment and only certain agencies and groups have access to them. Good job Hector.

  3. Specifications for many GPS receivers indicate their accuracy will be within about 10 to 50 feet (3 to 15 meters), 95% of the time. This assumes the receiver has a clear view of the sky and has finished acquiring satellites.Many receivers include WAAS capability, which can enhance accuracy in many parts of North America. But if you're moving around or in areas with less than ideal conditions, you'll probably find your receiver isn't using WAAS a good share of the time.
    GPS systems work in different ways, some are better suited to specific environments, some are free, and others have ongoing charges.
