Astronauts blast off into space aboard rocket ships. In space, they may do research, grow food, and help repair their ships. Beginning readers hone their phonics skills while learning about space crews and the people on them. As readers practice decoding words with the long vowel teams oo and ew, they gain science knowledge. Every Stairway Decodables nonfiction book combines multiple aspects of the Science of Reading to support small group instruction, independent reading, and reading practice at home.
