What are the three stages of the Concrete-Representational-Abstract (CRA) approach to teaching mathematics?

• Concrete, Pictorial, Abstract

• Concrete, Representational, Abstract

• Conceptual, Relational, Applied

• Calculation, Reasoning, Application

Why is the Concrete-Representational-Abstract (CRA) approach considered important in mathematics education?

• It ensures all students learn at the same pace.

• It allows students to make connections between different forms of mathematical concepts.

• It primarily focuses on memorizing algorithms.

• It is only beneficial for students who struggle with abstract concepts.

How should the Concrete-Representational-Abstract (CRA) approach be implemented for optimal learning?

• By strictly moving from concrete to representational, then to abstract in separate lessons.

• By focusing solely on abstract methods for advanced students.

• By integrating concrete, representational, and abstract elements within the same activity.

• By providing only manipulatives for all mathematical problems.

What is the recommended approach for implementing the Concrete-Representation-Abstract (CRA) model in mathematics education?

• Teach each phase (Concrete, Representational, Abstract) as separate, distinct lessons.

• Focus solely on the abstract phase once students grasp basic concepts.

• Integrate all three phases within the same activity to build deeper connections.

• Introduce the concrete phase first, then move to representational, and finally to abstract in a strict linear progression.

What is a primary benefit of integrating the Concrete-Representation-Abstract (CRA) model in mathematics instruction?

• It allows students to skip the concrete phase if they are quick learners.

• It simplifies the teaching process by providing a rigid, step-by-step curriculum.

• It helps students develop a deeper number sense and make stronger connections between different mathematical representations.

• It primarily benefits younger students and is not applicable to higher-level mathematics.
