Achieve!: Grade 1

This photo-based workbook series was designed by Houghton Mifflin Harcourt, a global leader in education serving 60 million students worldwide. Achieve! offers a comprehensive curriculum with a funny bone. Vibrant photographs form the center of each activity: math, reading, science, and social studies. The book's central character is Cosmo. Cosmo appears on selected activity pages to help extend ideas to every day life.

Whether it's used as a summer refresher or for weekend reinforcement, it's the perfect tool to nurture kids' natural interest in the world and how it works. In the Achieve! Grade 1 workbook, kids have hundreds of opportunities to practice Common-Core aligned math, literacy, science, and social studies skills. Count to 120, add and subtract within 20, tell and write time, distinguish between long and short vowel sounds, and explore model citizenship.
