We have created a great 3-5 days PowerPoint on Transparent, Translucent, and Opaque. It has KWL, prior knowledge, vocabulary, graphic organizers, full lesson plan, whole group lesson, small group lesson, and individual assessment to check for understanding. I am very excited about using this in my own classroom this year! ;) If you like this, then you need to purchase my Transparent, Translucent, and Opaque Activities. It is 12 printable pages that goes right along with the PowerPoint/Adobe document.
