Modeling Fraction Operations with Parallel Resistor Circuits
by Abraham Rosengard
Students will explore mathematical rules for combining fractions with unlike denominators by modeling equivalent resistance calculations for resistors wired in parallel electrical circuits. Using a simulation on TinkerCAD, they will select resistor values to calculate the total resistance. This cross-disciplinary investigation into fraction arithmetic concepts through hands-on electronics projects and verification of Ohm's Law relationships will build procedural fluency and conceptual links between mathematics and electrical engineering contexts.
