1st and 2nd graders--Lego sort

As a quick and fun activity (and to practice communication, collaboration and sorting) groups of 3 students worked together to sort Legos based on 4 properties of their choice. After each sort they took a photo with the iPad. When they were finished with their 4 sorts they imported the photos to PicCollage and created a poster with captions explaining their sort criteria.

A skill to discuss--poster appeal--can your audience read the captions?
