Welcome to the 1st Math Book Magic Monday! Each Monday I will post an entry about a magical math book.

Since 7/10/2017 is the first day of a week full of palindrome dates (see sidebar for more on this), this week’s post is inspired by my little palindrome-aged child. My son Landon turned **1** year old last month.

I know, **1 **may not be exciting to some in palindrome number land, but it was exciting for our family. A few weeks before Landon’s birthday, I checked out a bunch of library books with the number *one* in the title. Below is the low down on a magical math book starring *one *lonely fish.

**The Book**

*One Lonely Fish* was created by Alan Mansfield (concept and design) and Thomas Flintham (illustrator). It was published by Bloomsbury Children’s Books in 2017 (originally published in Great Britain in 2016 by Templar). It’s a larger-sized board book measuring 9 1/8 inches by 11 1/2 inches.

The book begins with one, little lonely fish. A second fish arrives, but he comes with his mouth open wide to eat the little, oblivious lonely fish. The pattern continues until one gigantic fish gobbles the sequence of nine smaller fish. The story ends how it began with one lonely fish.

**The Math**

*One Lonely Fish* is a counting book from 1 to 10. This book is great for children developing one–to-one correspondence as each page offers a new opportunity to count. Below is the page for eight. You can see the uniquely shaped page design in the photo.

This book reinforces the connection between counting and cardinality. Cardinality is a measure for the number of objects in a set. For example, on the page for 8 fish, 8 follows 7 in the counting sequence and 8 stands for a set of eight fish.

**The Magic**

The day I brought *One Lonely fish* home from the library (along with a 10 or so other math books with *One *in the title) my two older children (ages 7 and 4) searched through the piles of math books. They both grabbed for *One Lonely Fish* and attempted to share it as they flipped the pages. A few pages in, a struggle ensued. My daughter exclaiming, “It’s my favorite!” The fighting continued despite my rational response, “But look there are so many other books!” Tears. More fighting. More tears.

There is something about the book’s vibrant colors, it’s triangle-shaped pages that get smaller and smaller, and the growing sequence of fish for the BIG lonely fish to chomp down on that was appealing to my kids and I suspect others. This is why *One Lonely Fish* is the selection for this inaugural math book magic Monday.

I would recommend this board book for toddlers, pre-school aged children and kindergartners. WARNING if you have toddler sharks in the water: Landon took a bite out of the library copy. It is durable, but perhaps not toddler teeth proof.

**Thoughts?**

I am one lonely fish out in this big blogosphere sea. Feel free to drop me a line in the comments or follow me on twitter (@KellyDarkeMath).

Thanks and see you next Monday! #mathbookmagic

You really make it seem so easy along with your presentation but I find this matter to be really one thing which I feel I might never understand. It kind of feels too complex and very vast for me. I am taking a look ahead to your next put up, I’ll attempt to get the grasp of it!

Great point Alex! The sidebar is no longer there! Originally it said something to the effect of: A palindrome is a number/word that reads the same backwards and forwards. For example, BOB or 101. And so a number corresponding to the date July 10th, 2017, namely 7102017 (or 71017 if you prefer), is a palindrome (if you disregard the 0 that is sometimes written in front of the month AND you are in a country, like I am, where the month is read first). Also, the rest of the week (and then some) works the same way if you disregard the 20 in 2017: 71117, 71217, 71317, 71417, 71517, 71617, 71717, 71817, 71917. Hope this helps. Thanks for reading!
