In Unit 1, students read carefully selected pages of the anchor text, One Well: The Story of Water on Earth to build background knowledge about where freshwater comes from and about the three issues that the book describes: access to water, demands on water, and water pollution. Students begin by hearing pages of the book read aloud to determine the main ideas and supporting details of a read-aloud. They also reread the pages to analyze the illustrations and answer vocabulary and text-dependent questions.
For the mid-unit assessment, students listen to new pages of One Well read aloud to determine the main idea and supporting details before rereading the text to answer text-dependent questions. In the second half of the unit, students read pages of One Well paired with additional complex informational texts to compare the main ideas and supporting details of both texts. For the end of unit assessment, students read a new informational text to determine the main ideas and supporting details before comparing it to pages of One Well.
