Fairies, butterflies, and magic help to make this math-focused picture book from Danica McKellar, the New York Times bestselling author of Goodnight, Numbers and star of The Wonder Years , positively enchanting! Join ten flower friends for a night of excitement that mixes a little math with a lot of magic. As each flower turns into a butterfly, children will discover different ways to group numbers to create ten, an essential building block of math, all while watching each flower's dream come true. (And keep an eye out for the adorable caterpillar who wishes he could fly, too!) In this, the second book in the McKellar Math line, actress, math whiz, and New York Times bestselling author Danica McKellar once again sneaks in secret math concepts to help make your child smarter and uses her proven math success to show children that loving numbers is as easy as a wave of a wand and a BING BANG BOO!

Parent Magazine

Review: Great to teach your kid the fun of learning math! - Math is fun! Really, math IS actually fun, specially if you learn it from an early age. Books like this are the secret sauce to kickstart that sense of wonder and science and nature; and if you child manages to keep that healthy curiosity all the way up to the adult age, expect him to have a bright future (math is essential to land high-paying jobs in the tech industry, for example). This lovely book by Danica and Jennifer is meant to teach your small child all the different ways to sum two numbers and get 10 as a result. After this book, your kid will know that 10 is sum of 2 and 8, of 3 and 7, and many other ways (how many?). This seems like an easy task, right? For us adults it is indeed, and for your kid it will be too after this book. And if your child enjoys this book, there is lots more to explore after that. For example, tell your child there is a game based on this! It's called "Kakuro", and it plays just like the well-know Sudoku: you have to fill in numbers in a grid, but this time the number must sum to given value. If the value is "10" and there are two empty cells, then the answer will certainly be one of the combinations we have learned in the book, such as 3 and 7! (To find out which is right combination, you need to check the other clues, just like a crossword). You may also be surprised to discover there are mathematicians who dedicate their life to study the very same problem posed in the book, of describing a number as a sum of other numbers. They call it "the partition problem". We have seen that 10=7+3, but if we allow more than two numbers, how many combinations there are? We can write 10=3+3+6, or 10=1+5+4, or my favorite 10=4+3+2+1. There are 42 different combinations! And, as it turns out, to this day no one know a formula to discover the number of partitions of a number, without calculating first the partitions of all number that comes before it. We can find approximations though, one of them was found by the great genius from India, Srinivasa Ramanujan. Hollywood just made a movie about him, search for "The Man Who Knew Infinity". There is even a scene in movie with him explaining the partition numbers and calculating the approximation! There are so many stories that you can tell your kid after this. Another example: see how math in this book is made with poetry? It even has rhymes! Wouldn't it be fun if mathematicians used poetry and rhymes to express mathematics? Well, this used to be the way in the past! Certainly you must remember the quadratic equation (minus b, plus or minus the square root of delta, and so on). There is a formula for the cubic equation as well, and the person who created that formula, the italian mathematician Tartaglia, presented it to world in 1539 as a rhyming poem! Search in google for "Tartaglia's cubic poem", your kid will enjoy to know that! Math is incredibly fun, and this book might be the one to unlock the potential in your child. Danica's text is great and Jennifer's illustrations are amazing (I must say my favorite character is caterpillar engineer). Don't pass it up!
Review: Cute and engaging intro to basic math - Cute and engaging book to intro math concepts. My almost 4 yo daughter started showing interest in addition, and she loves butterflies, so I purchased this book and it did not disappoint. The story is easy to follow and there are multiple math concepts - counting forward, counting backward, adding, subtracting - without the content feeling overwhelming. My 2 year old likes the pictures and the story, and I like that he’s getting exposure to counting and basic math without pushing anything on him. The focus is definitely more on math than a really creative, heartfelt story, but if your child is showing any interest in math, or likes flowers/butterflies/fairies, I would for sure recommend.

### ⭐⭐⭐⭐⭐ Excellent way to teach young children combinations of ten!
*by D***Y on August 5, 2022*

This is an excellent and fun way to teach reading and a very important basic math skill! I am a retired elementary teacher (taught first, second, and fifth grades). As a fifth grade math teacher, I realized one of the common inteferences with student math success was lack of the basic earlier grade level skills of number sense. One very important skill is being fluent in the umderstanding of combinations of ten. This book with it's beautiful illustrations and story line meets that need! Additionally loved the encouragement for parents to teach math as an integral part of their child's life ... so important. How to get the most out of "Ten Magic Butterflies" was a guidance that I feel sure parents (and teachers) will appreciate.
