Origami and Math: Simple to Complex (Dover Origami Papercraft)

The purple flowers in this picture were made from this book. They have the correct number of petals, unlike a traditional origami lily. John Montroll does this with what he calls a five-sided-square base. I loved learning about both the geometry and the art, the algebra and getting animal proportions right. It is not hard to understand, and most projects do not take long.

I buy everything by Montroll.

My boys are not crafty in any sense of the word - they hate to color, refuse to do simple craft projects, but love math. This was a perfect marriage of the two. My six year old occasionally got frustrated by harder activities, but easily got the simple ones. My ten year old was happy with the whole thing.

As a mathematician, I was hoping for some in-depth math analysis and was disappointed to find little simple angling math only. Seems to have been better being sold as another origami book with folds. No real theory or math behind the works.

Good purchase.The models help you learn and are helpful to understand certain reasons for doing things.Its worth having in your collection for reference and just for the one model that usually takes 6 pieces to make is made with one…the yellow one on the left side of the cover near the elephants head…

Neat book

I bought this for my 12 yr. old grandson who has a passion for origami. He folds every paper that he sees! He was not interested in the math behind it all so this was a waste of money at this time. Maybe someday he will be into the inner workings of something he finds fun with.

I have everyone of John Montroll'sbooks - and this like all that came before it is a gem. Some interesting models. I really like the elephant in this book. The correlation between Origami and Math is fascinating. While I still cannot wrap my brain around all of it - it is still over the top.

Very nice models. I found it very interesting.The math remarks are very interesting, most of all about geometic constructions by folding and folding location of landmarks.If you are interested in landmarks or computation of proportions or angles, you'll enjoy this book.Besides, it contains some animal models, with remarks about the proportions (that is the mathematical aspect).It is not intended to be a whole exhaustive volume about all aspects of origami and math. In that sense, the title may be a bit ambitious.It does not contain kusudama or modular origami.Neither it is a classroom book or a pedagogic activities book.Nevertheless, if you teach math, some models contain interesting geometry lessons you can exploit in the classroom.

It's a fascinating book, with lots of interesting figures to fold. Working from basic flat triangles that teach you how to properly fold and understand the concepts of geometrics, this book takes you through some useful concepts, helping to understand how a three-dimensional figure is really just a bunch of flat pieces fitted together. It's helped my son with his geometry and turned from a bit of educational fun into a hobby.
