Interactive Fraction Comparison Practice (based on Guillaume Lesprit's idea)
Loading the math board and drawing, please wait…
① This example is an interactive drill for comparing two fractions, generating random pairs for students to judge which is larger, with a timer and score feedback. ② Core math concepts include fraction comparison, common denominators, least common multiples, and ordering of rational numbers, along with ratio and number sense. ③ Construction highlights: using GeoGebra commands Point, CircleSector, and Sequence to build visual elements; objects n1, d1, n2, d2 store numerators and denominators; points A, t, C, H and a chronometer manage interaction; text objects texte1-texte4 display prompts and feedback; Button1 (Bouton1) generates new problems; lists L_1 and L_2 track progress; slider vitesse adjusts speed. ④ Suitable for upper elementary to middle school students for self-paced practice, and for teachers in classroom demonstrations or gamified math learning, reinforcing strategies for comparing fractions.
