I used MosaicMaker. I enjoyed finding photos and playing around with all the ways I could compose them. You could spend ALL day doing this. I think in my classroom it would be really neat to create little cards for each student. For example, create a card with all sorts of butterflies and on the back of the card list facts about butterflies. The students could use their cards during Readers & Writers Workshop and at the end of the unit, the cards would be theirs to take home. Too cool. I'm excited about using this program in the Fall.
