Which of the following can be used as assessment strategy to encourage interdisciplinary in Mathematics? A. Projects B. Field trips C. Anecdotal records D. Olympiad

Projects allow students to integrate mathematics with other disciplines like science, social studies, art, etc., encouraging interdisciplinary learning. Field trips provide real-world contexts where mathematics intersects with geography, history, science, and culture. Anecdotal records are an observational assessment tool not specifically interdisciplinary. Olympiads are typically subject-specific competitions. Hence projects and field trips best promote interdisciplinary assessment.
