Here s the question parents ask at the end of every school year: How can we help our kids prepare for the next school year, while allowing them to enjoy their summer vacation? Here s the perfect answer: short lessons presented in a daily schedule for 8 weeks. The Monday Thursday lessons cover a variety of grade-appropriate subjects. Friday s lessons are fun, brain-teasing kinds of activities. Each book for Grades PreK 6 includes over 300 stickers that can be used to track progress and reward good work.
