Mega Machines takes readers to a busy, noisy construction site to watch the bulldozers, diggers and cement mixers in action, constructing a new school. In this Level 1 DK Reader children just beginning to read will be part of the action — from preparing the site to adding the finishing touches and having a grand opening ceremony. DK Readers is a multi-level reading program guaranteed to capture children's interest while developing their reading skills and general knowledge. With nine new exciting titles to choose from this season, kid's ages 4-10 will find the perfect book at their appropriate reading level to help with school projects or independent reading. Supports the Common Core State Standards.
