Excellent children’s book on perseverance!
Format: Kindle, Format: Kindle
This is the seventh story about little Nick in the “World of Kids’ Emotions” series by author Elizabeth Cole.
I have read all the books in this series and have shared them with my young grandson over the years. Emotions can be difficult for boys and girls too!
I like how in this story Nick is trying rollerskating! He’s not doing very well and gets discouraged. Fortunately, his father offers some encouragement to persevere and keep at it!
His mother tried baking cakes. At first she did not do a good job, but later mastered the skill of baking cakes. Other examples are used throughout the book to show that trying to do your best and having a goal are great ways to approach persevering!
“Perseverance makes me stronger.” I love the positive messages that are in this book. Positive self talk and encouraging oneself are helpful tools. “No matter the outcome, at least I did try!” ”My dreams will come true because I believe in myself.”
There are some positive affirmations at the end of the book. And also a free coloring page that can be downloaded with a scan code.
The illustrations are very nice to look at and colorful. The artist did a lovely job. The illustrations go along with the storyline nicely.
The writing in this book has a pleasant flow with lots of rhyming words. “Perseverance means not quitting right away, but keep trying more and more, day after day.”

Never Give Up

This is a wonderful story, told in rhyme, by Elizabeth Cole. It’s about a boy named Nick who who falls the first time he tries his new skates. Dad and Mom share their own experiences and how they didn’t give up trying new endeavors. Eventually, Nick finds success after following his parents’s advice with gaining confidence along the way. He realizes that persevering had made him a stronger person.
Ms. Cole’s book is a must have in any teacher’s classroom library and used to create thoughtful discussions about never giving up. The illustrations are visually pleasing which will engage children. This book receives my highest recommendation.
