Feb 04, Badlydone numberkand it it was amazing Shelves: I bought this book for my eight-year old a math nerd in the makingbut the entire family enjoyed it so much that I had to write a review. Hilbert are owners of Hotel Infinity where every number integer has a room. Of course, as a consequence, the hotel has an infinite number of rooms. However, Zero shows up at their doorstep and wants to stay at the hotel. How does one go about getting Zero his own room?
And what about the fractions who also make an appearance and would like to I bought this book numberand my eight-year old a math nerd in the makingbut the entire family enjoyed it so much that I had to write a review. And what about the fractions who also make an appearance and would like to dat in the hotel?
The Cat in Numberland addresses several complex mathematical concepts such as countable and uncountable infinities in a very clever and numbrrland way. It is a short read 56 numberlwndbut manages to entertain, inform, and stimualate those brain cells.
A must-read for young and old, math phobics, and “math philics”.
I must not fail to mention the clever artwork that accompanies the story – we spent time going over each picture to see if anything of interest was hidden! Feb 19, Dolly rated it liked it Recommends it for: Fascinating book about infinity. The concept is mind-boggling, and I found myself sympathizing with the cat since I couldn’t fathom the enormity of it myself either. But I loved how the author explains the idea and at least we get the general concept. The black and white illustrations are simple, but entertaining and our girls thought it was funny that 1, makes an appearance in the story several times.
We enjoyed reading this book together. Nov 10, Rosa rated it liked it Shelves: Interesting, kind of funny. Like The Number Devil: A Mathematical Adventure for younger kids.

I wonder if Mr. Hilbert miss their cat. Dec 28, Jo Oehrlein rated it liked it Shelves: Did a good job of explaining the Hilbert hotel concepts.
Did less of a vat job when talking about other things that were tossed in — like the 4 games that the numbers could play adding, subtracting, multiplying, and dividing. Mentioned that not any 2 numbers could play division, but didn’t say anything about limits on subtraction. Didn’t change the division limits once fractions entered the picture. I did love the single variable algebra problems that were introduced when the letters came to p Did a good job of explaining the Hilbert hotel concepts.
I did love the single variable algebra problems that were introduced when the letters came to play. Jan 30, Chris rated it really liked it Shelves: I had checked out this ‘ Flatland for Infinity’ on a recommendation, but wasn’t too sure about it. The kids wouldn’t let me put it down.
We normally do this sort of book a chapter at a time over a few days, but they insisted we read it through cover to cover in one sitting. Bravo Mr Ekeland — we’ll be sure to look into your other works. Aug 31, Alison Tripp rated it really liked it Shelves: The story is humourous and the cat is great. Introduces fractions, the idea of infinity and discusses additon, subtraction, multiplication and division.
Ct great for students struggling in math as a supplement but entertaining. I would reccomend for 4th and 5th graders and encourage a Hotel Infinity follow up activity. Maybe have un kids “play” the games the numbers did role play math problems. Dec 27, Jessie rated it liked it Shelves: This is a fantastic depiction of the proofs involving Hilbert’s hotel. I love the inclusion of both letters and numbers and also the defense of zero!
I didn’t particularly like the arithmetic games. With only number,and of each number, it’s not clear how the games are played; wouldn’t be possible to play. Also, 0 can be divided, even though 0 can’t divide, and it would be very boring to play addition, subtraction, and multiplication with 0.
Talking about “The Cat in Numberland”
The poor confused cat. Apr 07, Jeri rated it it was amazing Shelves: The cat stays in Hotel Infinity where all the numbers reside in their respective rooms. But what happens when zero comes numberand needs a room? What about when the letters need to stay the night? And how on earth do they accomodate all of the fractions? It’s nummberland a great story with a bonus of kids learning about math concepts. Aug 09, Jenny rated it nhmberland liked it Shelves: I read this to my 5. The cat that lives at the hotel with all the numbers is finally so baffled by the fact that the hotel is full but there is always more room that he moves away.
Jul 08, Donna rated it it was amazing Shelves: I borrowed this book from the library for my 2nd grader. He read it cover to cover in one sitting.
The illustrations are whimsical. The writing is direct, simple, and clever. It makes the concept of infinity accessible and fun. Jun 03, Jaime rated it liked it Shelves: TRuman is into numbers lately, and we started reading this chapter book about a cat in numberland.
Kn is loving it, and we ar reading a chapter a night, or at least part of a chapter.

It is a great book for him, and I love how intrigued he is with numbers, and math. May 17, LibraryCin rated it liked it Shelves: A cat lives in Hotel Infinity and is perplexed by how many different numbers and fractions can be added into the cwt, each with their own room.
The illustrations are very well done and do help explain.
