Nix the Tricks
This year I hope that every math teacher could make a commitment to teaching solid mathematical procedures that are fully developed and conceptually built. What I mean by this is that we should only teach procedures that we can explain mathematically to students including the reasons behind why the procedure works. When we teach students a procedure that we can't really explain mathematically, in student terms, we are reinforcing a "trick" or a "gimmick". Imagine if every year a student was taught at least 1 and more likely 2 or 3 new tricks to solve problems. Over time that is a lot of tricks without any mathematical foundation. Far too often I work with students in middle school, or even high school, who know little math and a lot of tricks. Given a new problem, all they can do is try to remember whether this situation calls for KFC, PEMDAS, or the Butterfly. This makes me sad because I want our future citizens to be more math literate and have a sense of number to rely on. Reasoning in mathematics means students explore many ways to find an answer and how efficient and effective those processes are. If we continue to drill instruction down to tricks and shortcuts, we have removed all the reasoning, and thus all the beauty that mathematics can truly offer. If you vow to Nix the Tricks this year, then check out the linked site where you have access to a downloadable, FREE, book on all the common, and some uncommon, tricks we have all been guilty of teaching and some ways to reinforce the development of mathematical understanding in students instead.
Are you EduSMART?
Recently I joined EduSmart as part of a growing team to support math and science instruction. I believe that Edusmart is the one of the best compliments to the curriculum resources already in the classroom. And you may not know that the Texas version of EduSmart Math is 100% aligned to the TEKS in grades 6 through 8 and was approved as 100% conforming during the 2014 textbook adoption process.
EduSmart's video based instruction supports teachers with content delivery using animation that engages kids, while the characters develop deep mathematics and real connections through modeling. What a great tool for not only supporting a teacher's instruction, but also as a review tool for students to hear the content in a new way and support what was learned in class. EduSmart can also be a fun and easy way for math teachers to begin flipping their classroom since the video content is already created. In addition to the video instructional components, EduSmart lessons also have guided notes for students to keep up with learning, practice to reinforce learning, and several online and offline activities to apply learning in real contexts. All of this at an affordable campus price. If you are interested in learning more check out EduSmart Math today. And if you have questions or thoughts, please email me anytime!

Order of Operations: The Myth and the Math
In this article the authors confront 6 of the common misconceptions about the Order of Operations as we know it today. Covering issues such as "the order of operations is rigid" and "the order of operations is best taught using memory triggers" definitly hit home with me. If you read my above commentary on teaching solid mathematics, these two common misconceptions by teachers and how to correct it in our teaching really got me excited. The authors also address the math behind the process, helping readers understand how to use the order of operations to teach conceptual math and build a stronger base for our young students.
My favorite quotes from the article:
"Preparing mathematically proficient students requires that what is learned is understood - every day, all topics."
"When we teach order of operations in a rigid way, students miss out on opportunities to look for efficient approaches, a critical component of procedural fluency."
Be sure to read the entire article from Jennifer M. Bay-Williams and Sherri L. Martinie!
Math Cut Ups Featured Title: Two Wrongs and a Right
This month I'm featuring Two Wrongs and a Right because it goes with my topic this month of Order of Operations. The focus in this activity is for students to think about the process and not just find an answer. In a small group students review a set of 9 cards in 3 colors. These cards represent 3 order of operations problems, each presented with 3 solutions as a colored set. For each of the 3 problems there is one card showing a complete and correct worked solution. The other two cards show worked processes that are incorrect. Students have to determine which of the cards in the colored set is "right" and which two are "wrong" and place them correctly on the mat. When ordered with the right solution and then the two wrong solutions on the mat, small letters on the corner of the card set spells a word to make the set self checking for the students. When finished, groups can trade card sets and work through 9 more cards (3 more problem sets). I recommend a recording sheet where students also have to state the mistakes that were made on the "wrong" cards to show they really understand the solution and the mathematical process.
Each package comes with 10 full sets (5 sets of A cards and 5 sets of B cards, and 10 placement mats) so that you can put students in small groups of 3 and have everyone engaged. All materials are pre-printed on colored cardstock. Each package is just $15 and comes ready to laminate, cut, and use!
