Seven books for a weather-and-seasons unit, and the honest truth about a weather shelf is that half of it is science and half of it is literature, and your students need both. Some of these are weather as a feeling: a boy alone in fresh snow, a city street when the rain finally breaks a heat wave. Some actually explain the machine: what makes thunder crack, why summer is the tilt and not the distance, where rain goes and comes back from. Hand each student the one that fits their level, and know before you do which book opens the unit, which one teaches the mechanism, which one settles the student who's scared of thunder, and which two are the read-alouds.
Different students can be reading different ones on the same morning. The thing to hold in your head is which kind of book each one is. Weather by National Geographic is the shared ground because it names the whole subject at a level a beginning reader holds alone, so start the unit there. Then the shelf splits in two. The Snowy Day and Come On, Rain! are the literature, weather as something a child lives rather than studies, and they are your read-alouds. The other three do the explaining: Flash, Crash, Rumble, and Roll takes apart a thunderstorm, The Reasons for Seasons settles why summer is warm, and Down Comes the Rain runs the water cycle as one loop. Match each student to the book that fits their level and their week, and keep one question under the whole unit: the weather you can feel out the window and the machine that makes it are the same thing, so which of these books shows you the feeling, and which shows you the works?
