Reach for Reading units are organized around a “Big Question”. This interactive bulletin board is meant to be used throughout the Theme 3: Water for Everyone as students explore the big questions of “Where does water come from? Where does water go?” Students show their understanding of the concept by writing or drawing on raindrops to answer the big question. The class can keep adding raindrops throughout the unit as they learn new information about the water cycle. You can use different colored raindrops for the different questions, or have your students write in different colors to answer the different questions.
