Describe two evidence-based math intervention strategies for students with disabilities.

• A. Concrete-representational-abstract (CRA) approach and explicit, guided practice with scaffolded instruction.
• B. Rote memorization and timed drills.
• C. Only visual-spatial worksheets.
• D. Unrelated computer games.

Answer: (A)

The idea being tested is which math interventions are supported by research for students with disabilities. Two approaches that consistently show positive outcomes combine helping students build understanding through concrete experiences with clear, guided support as they move toward abstract symbols. The concrete-representational-abstract sequence starts with tangible items the student can manipulate (concrete), then uses pictures or drawings to represent the same ideas (representational), and finally presents the symbols and equations used in standard math (abstract). This progression helps students see the connections between real actions and mathematical symbols, making concepts easier to grasp and apply in different situations. Pairing that with explicit, guided practice and scaffolded instruction means the teacher demonstrates the skill clearly, leads guided practice with prompts and feedback, and gradually reduces supports as the student becomes more proficient. This structured approach builds both understanding and procedural fluency, reduces confusion, and supports independence over time. Other options fall short because rote memorization and timed drills emphasize speed over understanding; relying only on visual-spatial worksheets limits the range of representations and may not build necessary procedural fluency; and unrelated computer games don’t provide targeted, evidence-based instruction.
