"I Know I Can" classroom poster

There are so many great messages buried in the music of the 1990s to early 2000s. And so much of it is completely unknown to kids in our classrooms! I know I sound like my parents about "the good old days of music" here, but back then music had a message and a meaning. It was meant to better us as a society and to bring us together. 

How to Use Algebra Tiles to Multiply Polynomials: with pictures!

I set a pretty average goal for myself a couple months ago to blog about all the ways to use algebra tiles. But then of course life got in the way and here I am only on post #3-- how to use algebra tiles to multiply polynomials. I'll get there, but it may take more time than anticipated!

My favorite use of algebra tiles is for factoring quadratics, especially where the A value is greater than 1. Using the tiles makes this process so much more concrete than any other method (in my opinion). Because it's my favorite, I jumped to blog about it first. But before we even get to factoring, we learn how to multiply the binomials, which is what this post is about.

But first! If you don't have a set of algebra tiles, here is a free set of printable paper algebra tiles. If you print on 2-sided card stock (like Astrobrights) it'll mimic the positive and negative sides of the plastic tiles.

Here we go!

How to Enlarge a PDF into a Multi-Page Poster for FREE! 3 Simple Steps

When I first started hanging math word walls on my classroom bulletin boards, I figured out a super roundabout way to enlarge a pdf to print on multiple pages. There were multiple conversions involved and the whole thing took entirely too long. So I enlarged a few things, put them up in my classroom and moved on. 

But I recently revisited this whole free poster thing because there had to be an easier way. And my "revisiting", I mean I asked in our Facebook group and got an answer in 3.2 seconds from a super helpful teacher Ms. Potter. And yes, I had been doing things the hard way!

I could very well be the very last person on Earth to know how to do this but like we tell students, "Always ask your question because guaranteed there is someone else in the room who is wondering the same thing." So if you are like me, here are 3 super-simple steps to enlarge a pdf into a multi-page poster. 

How to Eliminate Glare on a Laminated Classroom Word Wall

That glare from a shiny, laminated word wall is killer. Between the florescent lights and the windows, there's always somewhere in the room where the glare coming off the lamination blocks sight of the references underneath it.

I've been on the search for flat lamination pouches for a while now. I even tweeted Staples, who replied that they'd send the idea to their corporate office. To date, there are no flat laminating pouches at Staples. Or anywhere else. 

But there is an easy solution! I finally figured this one out today and I want to share it with you! 

So what's the solution?

Clear, flat spray paint!
