In the first unit of this module, students launch their learning about tools and work by considering the best tools for specific tasks. Students consider the unit guiding question, "Why do we need tools?" as they interact with and read about tools. In the first part of the unit, students build their knowledge of tools by engaging with a variety of texts and completing "tool challenges." Each challenge presents students with a dilemma based on the question, "Which tool is best for the job?" As students engage in the challenges, they discuss, ask questions, respond to questions, and ultimately experience using tools for themselves.
During the second half of the unit, students engage in a series of focused read-alouds of the book Tools by Ann Morris. Through this text, students continue to learn about why people use tools, discover new and various tools, and decide how tools help make tasks easier. Students practice sorting tools into categories while using their question-asking skills as they work with a partner on the sorting task. Students deepen their knowledge about tools when they read about the functions of specific tools in the index of Tools. The Unit 1 Assessment is a final, less scaffolded, focused read-aloud during which students demonstrate their understanding of the different types of tools through partner discussions, sorting, and informally providing a written response to the question, "What job does this tool help to do?" (RI.1.1, RI.1.7, L.1.5a, SL.1.1a, L.1.5a and L.1.5b).
