QUICK IMAGES

http://blogs.henrico.k12.va.us/math

Routine: The teacher will click to display the image. The image will only be shown for 3 seconds. Once the image disappears, students are asked to tell the quantity or draw what they can remember seeing. When the teacher sees that most students have drawn all they can, he/she will click to display the image for three more seconds. Once the image disappears again students will continue drawing. At this time, students can compare drawings and either discuss in pairs or as a whole class how they developed their drawings. The Quick Images routine develops mental imagery, builds vocabulary, improves spatial memory, and teaches students to analyze mental images.

Guiding questions: “What did you see?” “How did you draw it?” “What are figures that you see?”
