Curiosity leads to learning! Curious George Adventures in Learning is a researched series for early learners. It was designed by Houghton Mifflin Harcourt, a global leader in education serving 60 million students worldwide. Each workbook features 12 new mini-stories that provide context for math, reading, and science practice. These stories give children authentic learning experiences that naturally inspire curiosity. Children are more motivated to ask, learn, and retain information when they learn through stories. In the Grade 1 workbook, your child will practice and solidify math, literacy, and science skills. Extend counting to 120, add and subtract within 20, tell and write time, and distinguish between long and short vowel sounds.　 The workbooks also integrate social emotional activities to support whole child development. And they're mapped to the Common Core, providing valuable reinforcement of the concepts they learn in school.
