Use stacks of index cards (cut in half) to make simple flip books and discover how our brains can perceive sequences of still images as if they are in motion. #Candyland characters gingerbread man codeYou can also introduce the concept of debugging as a way to troubleshoot code that doesn't work as expected. Non-specific (or incorrect) directions can lead to funny mistakes in the activity and will help students begin to understand how precise coding instructions must be for a program to run properly. The science: Practicing writing concrete and repeatable directions to navigate from Point A to Point B helps students practice the kind of algorithmic and sequence-oriented thinking used in coding and computer programming. See also, 20+ Coding Activities for Beginners and Beyond.) For more inspiration about using an activity like this to introduce coding, see paper-based coding activity. Students can also color in the area around their path, adding in a forest, a lurking fox, or other creative storytelling elements. ( Tip! You can increase the complexity for older students by allowing them to add in bridges or obstacles to navigate and devising concrete single-block coding directions to match. Using only commands that involve moving x number of steps up, down, left, or right, can students successfully guide a gingerbread person along the path? Students can color in their own Candyland-like path on graph paper or on our free templates ( large graph for a simple path small graph for a longer, more complex path). Put a gingerbread spin on this paper-based coding activity by having students create a custom path from the starting point to the gingerbread house and then write the directions for someone else to follow.
