This tutorial is a fun way to make characters appear and reappear when the are tapped in a loop using Scratch Junior. ScratchJr is a collaboration between the DevTech Research Group at Tufts University, the Lifelong Kindergarten Group at the MIT Media Lab, and the Playful Invention Company.

The main Computing concepts covered in this tutorial are loops, broadcasting messages and debugging algorithms.

Challenge activities are to create a hide and seek loop with more than two characters and also to add sounds to the sequences.
