I just got my copy of the book, The Best of Math Teacher Blogs 2015. The book is a collection of blog posts by teachers involved in the online community, #MTBoS. You can read more about how the book came to be on Tina's blog . One cool thing about this project is being published alongside some teachers that I really admire! Another awesome thing is that proceeds of the sale of the book go to giving scholarships to teachers so that they can attend " Twitter Math Camp ." I've never been myself, and if it wasn't for having a newborn this summer, I would have tried to get there this year! The idea of meeting up with some of my Twitter friends and talk math sounds so fun! I do hope a TMC is in my future in the next few years!  I'm looking forward to reading all the great posts in this fab book. If you want a copy for yourself, click here ! If you want a preview of the post of mine that is in the book, check it out here . It really is one of my favorites! ...

I think to be a good teacher, you have to love teaching, love learning, love kids, and love your content area. You don't have to love them all equally and there can be parts of your job that you like better than others... but you certainly can't dislike the subject that you teach! So, I love math. My love of math has grown as I grow in my own understanding. But I do love it. I love how numbers work. Prime numbers? Fascinating! Dodecahedrons? Beautiful! Fractions? Useful!  ... and Pi? Yep, I love pi! Today happens to be Pi Day. This is my 11th year of celebrating Pi Day. I've done everything from bringing in pie, having memorizing contests, investigating the ratio itself, and circle drawing contests. I have been in my own little world, proudly wearing pi t-shirts and pi earrings! My family and friends know I like pi. My brother bought be a pi pizza cutter . My daughter wore a onesie last year that says "Cutie Pi." I myself have 30 digits memorized! ...

I haven't written about a lesson idea in a while! While talking with an 8th grade teacher today, I was reminded of a lesson I've done in the past about combining like terms. I wanted to write a quick post to share and also so that I can have it saved to refer back to. The lesson begins by showing this clip: The kids always laugh and enjoy the silliness of it. When it keeps going, I hear a lot of "You gotta be kidding me!" and "ugh, how long is this going to go on?" Perfect. I feel like I'm creating the controversy (create the controversy, Dan Meyer suggests is a first step) After the video, I talk about a simpler version of this same idea. Me: What if I ordered 5 hamburgers, 3 orders of fries, 6 hamburgers, and 2 more orders of fries. Is there a better way to order that is less confusing? Students: Yes! (they are almost frustrated with me!) Put the hamburgers together and the fries together. Me: Oh, so if I wrote ((write on the board:...
