Big One PowerPoint is a cross-curricular assignment meaning it has to be connected to school somehow.You pick the topic but connect (loosely) to school.
Examples: PE = any sport; ELA = any author/book series; Foreign Language = any country that speaks that lang; BOS = any thing with computers/gaming
You pick the topic and then complete the assessment based on the rubric. Your presentation will be 15 slides with slide 1 as the title slide and slide 15 as works cited. You fill in the rest :)
