The document describes a data wall created to display students' pre- and post-test drawings assessing visual-spatial skill development across grades K-5. The wall shows a sample of drawings from each grade level demonstrating the range of abilities within that grade. It also features direct comparisons of individual students' pre- and post-test drawings to illustrate growth in drawing level. The data wall is intended to track improvement in visual-spatial skills through a drawing-based curriculum and demonstrate how these skills are developed and practiced over time.
