Using a modification of the fraer model for vocabulary, students create cards for important Ecosystems vocabulary. The 4 quadrants include: the vocab word, an example/drawing, definition, and related words (for example, consumer and decomposer would be related words for producer). In the related words section, my students and I have started creating graphic organizers to show how the words are related. This year, I printed these on cardstock and had students cut them apart to create vocab index cards. Later in the year, we will add key concepts to remember about each word. Especially helpful if science is a tested subject in your state. You can download this and insert any vocabulary words you wish students to master in any subject.
