Early childhood is a time to encourage a love of learning and school with engaging  instruction that allows children to develop their natural curiosity. With comprehensive  curriculum, engaging libraries, and innovative applications for home and school,  Houghton Mifflin Harcourt provides young learners with every opportunity to build the  foundations for lifelong achievement in PreK–Kindergarten. As educators, it’s our job to  ensure that we give children new experiences and opportunities to expand their  knowledge and explore reading, science, math, social studies, art, and world language. Beginning with PreK, HMH prepares children for every transition by developing the skills  for academic, social, and emotional success.
