from 37 reviewsI am the Executive Director of Right to Life Kern County and I love to have this book on my table when I go out to events! It is so helpful to show people and children that the fetus is alive and growing from the very beginning! Thank you for a beautiful, educational resource for the pro-life cause!
These are great! Came at just the right time for a certain four-year-old asking questions about God making everything and also about germs and other things we can't see, like the wind, etc. She made it almost all the way through the first book without losing interest, which in itself was great!, but next time we look at it she will likely connect all the way through.
I like the gentle way that God is infused in the content--because our family has varying degrees of what is just right or too preachy for their kids--and how the graphics are accessible to any child (or adult) without seeming cartoony.
I have only skimmed the other books, but they look to follow the same template as Atom and Iota. Looking forward to sharing these with all the grandkids!
I ordered this book bundle for my 3 older kids, 6 and under, to be used in our homeschool time! I wanted something science based that centered the teachings around the gospel. They are so kid oriented and Christ-centered and our family loves them!!
gifted the books to my 3 year old grandson. We read them together. In a few years I think he will begin to understand how the designer made heaven and earth.
It is well written and shared the story of the Gospel powerfully.
My daughter and I are reading these books and she’s mentioned a couple of moments when she has made a choice to stop and respond differently that she was fighting a dragon and names it. We’re enjoying these books and appreciate the awareness that comes from reading them and discussing them. Thank you.
I ordered a 3-book series of Atom and Iota. I love that they help prime kids to question when science contradicts God. They teach kids to look for science to confirm God, instead.
Bought these for my grandkids, and they, and their parents loved them!
Amazing recourse for science that brings it all back to biblical truth! Thank you for making these!
We love them so far! Our Son is only 2 and a half but he thinks the characters are so fun and likes to turn the pages himself!
Child and I love the books. Accurate information a child can learn but not in a stuffy/boring way. Great idea to make the clever characters to help make the learning fun
