3. A Grade 8 EMI mathematics teacher introduces new academic vocabulary related to geometry. Rather than directly explaining the meaning of terms or correcting student errors, the teacher presents visual materials and colored rods and encourages students to work collaboratively to identify patterns and formulate explanations. When students make mistakes, the teacher remains largely silent and uses gestures or visual cues to prompt self-correction. The teacher believes that learners develop deeper understanding when they actively construct knowledge rather than receive it directly.  Which teaching method is MOST clearly illustrated in this scenario?
(A) Audiolingualism, which promotes automatic language production through repetition and reinforcement
(B) The Silent Way, which encourages learner autonomy, problem-solving, and self-discovery while minimizing teacher talk
(C) Suggestopedia, which emphasizes relaxation and positive emotional experiences
(D) Grammar-Translation, which emphasizes explicit explanation and translation exercises
