I have been teaching Moon phases for a very long time. Many of the worksheets I have seen for sale will combine a view of the Moon orbiting the Earth from a standpoint of looking down at the North Pole of the Earth. These same sheets also show how the phases look from someone on Earth. What they don't bother to explain is how the perspective changed from one view to the other.
This activity takes care of that misunderstanding. There is one activity sheet that should be duplicated for every person in your class. That i followed by 6 PAGES FOR THE TEACHER (cream colored) that go into step-by-step instructions on how to go from one perspective to the other.
In addition, Moon phase names are involved with an explanation of waxing and waning. Finally, students are instructed on how to easily figure out the amount of time for the Moon to move between phases and the parts of the day to see certain phases.
