This can be used along with the author’s devotionals or as a stand alone. As a certified teacher and homeschool mom I believe you could use the book as a science supplement for fourth grade and up and your curriculum for grades 1-3. It also would work well for activities for kids to do while waiting in appointments, church, during free time, travel, or anytime you need a quiet activity. Kids who like science will probably enjoy this book the most, but the colorful pages and variety of activities will appeal to all kids.
I highly recommend The Indescribably Activity Book by Louie Giglio.
I was given a copy by the publisher and not required to write a positive review.
