Which math task would likely pose the greatest difficulty for a student with impairments in spatial relationships and perceptual-motor skills?

The task of constructing congruent geometric shapes on graph paper would pose the greatest difficulty for a student with impairments in spatial relationships and perceptual-motor skills. This type of task requires the ability to visualize shapes, understand their dimensions and positions, and accurately translate those visual representations onto a flat surface. Impairments in spatial reasoning can hinder the student’s ability to comprehend how to manipulate and relate different geometric figures, leading to challenges in accurately creating congruent shapes.

Additionally, perceptual-motor skills are crucial for coordinating movements, such as drawing or tracing shapes, which are integral to successfully completing this task. A student struggling with these skills may find it difficult to maintain the precision needed for constructing shapes that are congruent.

While solving word problems, adding and subtracting whole numbers, and interpreting graphs and charts may present some challenges, they often rely more on other cognitive processes like verbal reasoning, numerical operations, and analytical skills rather than the specific spatial and motor coordination required for constructing shapes. Therefore, option B stands out as the most challenging for a student with these specific impairments.
