Visualization is an important reading comprehension strategy where readers create mental images of the text as they read. Visualizing text makes reading more personal and memorable by engaging readers' senses and prior knowledge. As readers visualize, they gain a deeper understanding of what they read and can recall it for longer periods of time. The document provides an example group activity where students visualize a story without pictures and compare their mental images to the actual illustrations. Individual visualization exercises are also suggested to help readers strengthen this important skill.
