Mathematics and Quantitative Reasoning
Gage programmed the digital marble obstacle course using the app, measuring lengths of ramps, angles, and timing each segment. He performed calculations to estimate travel time, added distances, and adjusted dimensions to balance difficulty. Through this process he practiced arithmetic, geometry, and proportional reasoning, and recorded results in a spreadsheet. His work showed how quantitative reasoning guides design decisions.
Science and Natural Inquiry
Gage explored physics concepts while building the digital marble race, observing how gravity, friction, and slope affected marble speed. He formed hypotheses about which obstacle shapes would slow the marble most, then ran multiple trials in the app to test his ideas. By comparing outcomes, he practiced the scientific method, analyzing cause‑and‑effect relationships. This hands‑on digital experiment deepened his understanding of motion and energy transfer.
Self-Management and Metacognition
Gage took charge of the entire project, setting a clear goal to create an engaging marble race and planning each step from sketching the course to coding in the app. He managed resources such as time, the app’s tools, and online tutorials, and kept a log of his progress. After each test run he reflected on what worked, identified improvements, and revised his design accordingly. This demonstrated strong goal‑setting, resource management, and reflective practice.
Tips
Tips: 1) Invite Gage to map his course on graph paper and calculate exact slope percentages to reinforce geometry. 2) Encourage him to research real‑world marble run videos, then design a new obstacle inspired by the most efficient ones. 3) Set up a mini‑presentation where Gage explains his design choices and physics reasoning to family members, fostering communication skills. 4) Introduce simple coding challenges, like adding a timer or score system, to blend programming with math.
