From the same wiseguy who brought you "Fractions: You're Teaching It Wrong," "Multiplication: You're Teaching It Wrong (and you really don't have to...), among other deals, I now present unto you, "Division: Take My Word For It, You're Teaching It Wrong."

It's 62 pages long! Okay, half of those pages are printable "division facts reminder & practice cards, but still, that's a lot of division for you to digest.

13 concrete techniques that you can implement into your classroom tomorrow, or, even better, steal and use in your TpT materials!

Here's what it be about:

• FYI: Division is Hard on the Brain - the neuroscience of this elusive and misunderstood operation.

• Modeling Division: ACTIONS! - you're probably developing incomplete concepts of division. Here's 7 examples of how you should be doing it, and it has to do with monkeys and bananas!

• The Language of Division: CONFUS-ING! Here's how to get your students to understand it once and for all...

• Those Pesky Remainders: Whole Numbers - How to help your students to really grasp what a remainder is all about.

• The Property of Proportionality: This technique can be used quickly and easily to slay even the most ferocious division problem. Why aren't you teaching it to your class?

• Property #2: Identities and Ones - Why are you teaching your students 100's of isolated division facts? Here's a way to cut it down to size....

• Property #3: Zero is dangerous! How to have a sensible and mature conversation with your students about the third rail of mathematics, 0.

• How to Memorize Division Facts: A neuroscientific approach to helping your students memorize the division facts with a minimum of tears and frustration. Includes a full set of printable cards.

• Bigger Division Strategies: Have you seen these three ways to avoid that dreaded "long division?"

• What is Long Division, Anyway? : In which I argue that there is no such thing and stage the Traditional vs. Multi-Step Division Throwdown. An algorithm that is both transparent and forgiving for doing complex division problems.

• Moron Remainders: Fractions - Just don't say "remainders over divisors!" Teach it in a way that is organic and understandable.

• Moron Remainders: Decimals - Why the current "long division" algorithm is short on "magic" and stuffed with "hocus" and "pokus."

• Division and Decimals: A New Path - turn fractions into the decimals using an algorithm which borrows techniques from computer scientists!

This is written so that you can take a subject as scary and intimidating as division and make it kinda fun and interesting. Seriously, the more you and your students learn about division, the more likely you are to get totally down with it. Seriously, there's some great stuff in here (okay, there are no "scoot" cards, and no cutsie graphic) that will really provoke deep thinking in your kids. And because I wrote it, lots of good jokes.....
