About Us

Welcome to Dorey Publications and thank you for your interest in
Mr. Dorey's Algebra Handbook.

My name is Kevin Dorey, owner of Dorey Publications and author of Mr. Dorey's Algebra Handbook.  I teach Common Core Algebra I at Pittsford-Sutherland High School, located in the suburbs of Rochester, New York.  When I began teaching Common Core Algebra I, I found myself in search of a resource that would support my students' learning; a place where they could turn when questions arise and that would have everything all in one place.  When I was unable to find quite the right thing, I set out to put together my own collection of explanations and examples that would become Mr. Dorey's Algebra Handbook.  

Today, my students use their Algebra Handbook often and it has become an invaluable resource for them.  I teach them how to use a math book (you would be surprised at how many don't know how to!) by having them look things up and preview topics at the start of class.  I sometimes ask students to use a particular example as a model for solving a warm-up question or to review an important concept.  In our class notes, we make note of which page of the handbook relates to the day's lesson and, when questions arise, my first response is an inquiry as to whether the student has consulted their Algebra Handbook. Typically students learn that they are able to find the answers to their own questions and that they don't need to see me after all.  Resource teachers, parents and others who support our students have similarly found Mr. Dorey's Algebra Handbook to be a valuable resource.

I invite you to explore Mr. Dorey's Algebra Handbook and consider how it can be of use to your students or your child as they learn and work toward mastering Common Core Algebra 1.  

The Algebra Handbook Timeline:  Our Story

2013-2014: New York State adopts the Common Core Learning Standards in Algebra 1.  Kevin Dorey, a high school mathematics teacher, purchases several different handbooks to trial with his students.  None of the handbooks meet his needs, so Dorey decides to create his own Algebra Handbook.  The first handbook, a humble 40-page booklet called "Algebra Reference Book and Study Guide," focuses primarily on functions and algebra fundamentals.

2014-2015: Pleased with the results of the first edition, Dorey sets out to create a more comprehensive handbook.  The revised book is now 77 pages long and includes more topics than before. The name "Mr. Dorey's Algebra Handbook" is adopted.

2015-2016: Dorey spends much of the summer working on a more complete version of the Algebra Handbook, which is published in September of that year. This version featured 115 pages and more closely resembled the handbook today. Kevin Dorey founds Dorey Publications and begins marketing the Algebra Handbook publicly.

2017-2018: The Handbook is revised again, this time to 120 pages.

2019-2020: A major update takes place with several sections completely rewritten, particularly the functions section of the book, to better meet student needs. The handbook is now 148 pages and was released just prior to the start of the COVID-19 pandemic.

2020-2021:  A large library of math tutorial videos is released on the Dorey Publications website.  This proved very helpful for many students who were learning remotely during the pandemic.

2022-2023: With the forthcoming implementation of the Next Generation Learning Standards in New York State, Mr. Dorey sets out to completely update and overhaul the Algebra Handbook.  Every page is reviewed with a majority revised and rewritten.  Dubbed the Next Generation Edition, the new handbook is 160 pages in length and is the most complete edition ever.  It was released in August 2023.
