Insightful, wise and practical!
Format: Hardcover
A highly readable mix of practical strategies, engaging anecdotes and research-based insights, Thrivers underscores the importance of our kids' innate character strengths for their success and happiness. I found this book perfectly timed, given all the pandemic-related stress our teens have had on top of everything else! Borba’s advice on recognizing and nurturing what really matters makes this book a parenting must-have (and I’ve read plenty of them).

Helpful pinpointing which traits to focus on
Format: Hardcover
I loved the format of the book, how are you take a diagnostic test and then read the sections that pertain to the character traits that you want to strengthen in your child. But when I read the chapters, I was disappointed. I was hoping for new information. If I had never read a book on how to support my child’s development and education, I would have been delighted.

impressed with the quality and design
Format: Cards
much sturdier and better made than other flash cards we've tried. our son loves the size and reaches for these to play with frequently. nice to have a thicker box for bringing them with us to restaurants / travel that doesn't get ripped on the first usage.

Perfect for duo language learners
Format: Cards, Format: Cards
I love these cards my son received as a birthday gift, he started duo language program this school year and it’s been super helpful to help him practice at home. I also love the papel picado touch and that the colors are not so bright and in your face.
