Students use pair programming to trace, annotate and debug a prewritten Twine story. Students then add modifications to the existing code and extend the story.

Students will craft a Twine program with variables, conditionals, and relational expressions for a historical narrative on Westward Expansion. Students choose a project from a choice board & test products regularly during construction. Programs should offer multiple outcomes based on the user's choices or actions."

Students will engage in a discussion about the concepts of algorithms and loops. They will then apply the pair programming technique to collaboratively create an origami model. During the activity, students will closely examine the algorithm, represented by the origami instructions, and identify the 'loops,' ( steps that are repeated in these instructions).
