I have really got on board with Dropbox as a quick way for the students to do a picture rhyming sort. I got the sort pictures online and just took a screen shot. I correlated the rhyme with one that is covered on MAP testing (NWEA).
I have a file of different pictures for each rhyme. I am doing more than a rhyming pair as I think the students are quick to find the pair and then do not look for other pictures that match.
I upload all the pictures into Dropbox. The students click on each picture (labeled a, b, c, etc) and then sort the pictures. The students do this on Educreations and record for a second (some do it a lot more) and then save their work.
Here are some of the students' work, screenshot from Educreations:
All the students received this sort but I have also had different students go to different folders, marked A, B, C and then download the pictures in that folder which are designed for them. This is one way I can differentiate this activity for the students.
