This product uses Reading A-Z's "Volcanoes" booklet, appropriate for 3rd grade reading lexile. However, if you do NOT have access to Reading A-Z, each question contains a paragraph from which to read OR a map from the book. Thus, the booklet is not 100% necessary. The reason paragraphs are included is because this set of worksheets focuses on "hot text" features; in other words, the students need to highlight, underline, or circle causes and effects throughout their independent and group work.
The pages are set up and labeled with "Teacher Model," "group," and "independent." The independent pages are differentiated. The CIRCLE is "high" group and the Square/Triangle is medium/low. Personally, I pulled my lowest group to a back table so I could monitor their progress.
These were created within a larger unit for Cause and effect and natural disasters.
