Core Skills Analysis
Mathematics (Pre‑Algebra & Introductory Algebra)
- Applied the concept of variables and expressions while solving interactive Desmos activities, reinforcing the meaning of symbols in equations.
- Practised solving linear equations and inequalities from AoPS Intro to Algebra, developing procedural fluency and logical sequencing.
- Explored coordinate geometry by plotting functions on Desmos, linking algebraic formulas to visual graphs.
- Connected arithmetic patterns to algebraic generalisations, strengthening number sense and the transition from concrete to abstract reasoning.
Digital Technologies / Computer Science
- Wrote and debugged block‑based code in the LEGO Spike Prime environment, learning sequencing, loops and conditional statements.
- Integrated sensor data (colour, distance) from Spike Prime into decision‑making algorithms, introducing the idea of input‑processing‑output cycles.
- Created parametric sketches in Desmos, experiencing how mathematical formulas can generate dynamic visual output—an early exposure to computational thinking.
- Collaborated online with AoPS forums to discuss problem‑solving strategies, building digital communication and community‑learning skills.
Design & Technologies (Engineering & Robotics)
- Built functional mechanisms with LEGO Spike Prime, applying principles of levers, gears and torque to achieve motion.
- Designed and iterated wobble‑dog prototypes on wobbledogs.com, testing balance, centre of mass and material flexibility.
- Documented the engineering design process (ideate‑prototype‑test‑refine) for both LEGO robots and wobble dogs, practising systematic problem solving.
- Evaluated the performance of each design against defined criteria (speed, stability, programming accuracy), honing assessment and reflection skills.
Science (Physics – Motion & Forces)
- Observed how motor power and gear ratios affect acceleration and distance travelled by the Spike Prime robot, linking force and motion concepts.
- Measured angles of wobble‑dog tilting to discuss equilibrium and the role of friction in stabilising moving objects.
- Used real‑time sensor readings (e.g., distance sensor) to explore concepts of measurement, accuracy and experimental error.
- Connected the mathematical modelling of motion curves in Desmos to physical trajectories of the robot, reinforcing the maths‑science relationship.
Tips
To deepen the learning, have the student design a challenge where a Spike Prime robot must guide a wobble‑dog through a maze using only sensor feedback, then graph the robot’s speed over time in Desmos. Next, ask them to write a short explanatory report linking the algebraic equations they used to the physical forces observed, incorporating diagrams of gear setups. Finally, schedule a peer‑review session where classmates critique each other's designs against a rubric focused on efficiency, creativity, and mathematical justification.
