Third Grade Subtraction Voicethreads

Students in Mrs. Devlin’s Class have created these voicethreads to practice subtraction, teach others how to subtract, and see if anyone has a different way.  Check them out, and feel free to comment with your own method!

Note:  We did realize that you could keep the writing from fading towards the end of the project.  To see how, read how to increase writing time in voicethread.
