Prediction: Skip a phase for 7 days
Remember there are 3.5 days between each phase, but we use skip a phase for 7 days!
16
Skip a phase for 7 days
This means when I look at the diagram, to go from NEW MOON to FIRST QUARTER, 7 days have passed or you can add 3.5+3.5 to see how long it takes to get to FIRST QUARTER.
17
Skip a phase for 7 days
If I want to see how long it takes to get from FULL TO NEW MOON, I will skip a phase TWICE. This means I skipped waxing crescent AND waxing gibbous. If I skip twice it takes 2 WEEKS or 14 days.

Multiple Choice
Which moon phase would be found ONE WEEK after a WAXING GIBBOUS?

Multiple Choice
Which moon phase would be found TWO WEEKS after a WANING CRESCENT?

Prediction: Calendar Questions
Don't be overwhelmed! A calendar is a useful tool! Skipping a phase for 7 days just means move the phase down one week!
22
Prediction: Calendar Questions
If a new moon is on the 2nd, what moon phase is found one week later? A FIRST QUARTER ON THE 9TH, because it is 7 days later, I just move down ONE ROW on the calendar. I can keep skipping a phase for 7 days by moving down one row.
23

If a new moon occurs on the 5th, when will you see a full moon?
24
Multiple Choice
