A fun offering for English and Spanish learners alike with a mystery element that will hook its target audience. A great way to make math fun. ( )

This book contains short stories that children can solve either in English or Spanish. Each story is one minute long and at the end of that story there is a prompt to stop and think about the problem in the story. I recommend this book to English learners and even Spanish learners because they are challenged mathematically while learning a new language. ( )

This book is great short stories that are written in both English and Spanish. Mysteries are always fun, these mysteries include math. Any way to make math more fun is a great tool. it also allows students to see real world application. ( )

My class loves it ( )

I received this book as part of the LibraryThing Early Reviewers program. I did not read the whole book, but I did read enough (more than half, focussing on the Spanish side) to get a sense of the book. This is a series of short "how did they figure it out/what would you do" puzzles about math. It involves light geometry, proportions, probability, rates, arithmetic, and problem solving, and could definitely entertain a wide grade range. It is written in English and Spanish, (on facing pages, which I found useful when I didn't know a word), and then each mystery is solved on the next set of facing pages. The mysteries were set in the normal life of the kids - figuring out chores, getting the best price, playing a game, etc. There were a few math errors, but they were typos instead of math issues, and I hope they catch them in the next edition. A couple times there were assumptions about what kids know, for example how big a soda can is, but actually, if you were reading this with a kid, you could go find one and look, which would be part of the fun. As a full-time math tutor, I am glad to know this book exists and expect that I may be able to use some of these interesting problems with my students. ( )
