Sometime in the fall of 2016, I invited students to my AGOO; however, I ran into difficulties because my students are too young to have email accounts. I used the first option, "Add members without sending emails" and used my email. It worked.
In October 2016, I created a group, Earth System Science 6, in my AGOO. I created two lessons and added them to the group folder. Students work on their map and submit back to the group, where all maps reside.
The students are able to work on their maps on the iPads and on PCs in our school computer lab. It has been working out pretty well.
I entered 4 students in the Middle School/High School Map competition, just to jump in and get feedback on my students' maps. I have found Dr. Waverly Ray to be very helpful and encouraging.
