The activity that we did can be done on both the LearnPad and the iPad. While the apps used to complete this activity were different, the end result turned out the same.
In an attempt to have my students apply their learning while creating and collaborating, we annotated a time on an analog clock and posted it to a blog. Having students annotate a time on an analog clock required them to apply their understanding of Common Core Standard 1.MD.B.3 which requires 1st graders to tell and write time in hours and half-hours using analog/digital clocks. To add an additional layer to this activity, students then went to their peers' blog posts and left a comment with the digital time that the analog clock was representing.
Below is a video that highlights how this activity was done in my class as well as how it can be done on both LearnPads and iPads.
