Order of Operations Posters

Next up in the back-to-school posterpalooza, it's the order of operations. I've heard different people have different opinions between GEMA and GEMDAS. I like the idea of arranging the letters like this as a compromise between the two. It emphasizes that multiplication/division and addition/subtraction occur in pairs, at…

Inequality Symbols Posters

Okay, before I go any further, I feel I should clarify: I have not just been working on posters for the last week, despite them completely taking over my blog. I have been working on lesson ideas, too. I just want actually try them out in class, so I can…

Converting Units Posters

I'm a Geometry teacher who doesn't know how to measure anything. Okay, I can measure stuff. But, like most of the world except the nation I now live in, I learned* to measure everything in metric. Mostly. I grew up on a farm, so I'm very used to measuring area…

Classroom Rules Posters

This tweet basically summarizes what the last week has been like in our house: Rest assured, all. Laminating continues because we found an unopened box of 100 pouches. @reilly1041 @theshauncarter @druinok @misscalcul8— Sarah Carter (@mathequalslove) July 31, 2016 The latest contribution for my walls are my classroom rules: These…

Parent Functions Posters

New posters today for Algebra 2: Parent Functions! I actually put these up a couple of weeks ago, but unfortunately didn't have any photos of them. Then the floors of the school hallways got waxed and we weren't allowed in. Until today! Here's them next to my Geometry Symbols Posters.…

Geometry Symbols Posters

Firstly, my recent exciting news that I don't think I've blogged about yet: I have a job at the same school as my wife! :D I have my own classroom! This was in doubt for a while, as it seemed I might need to be a roaming teacher (which didn't…

VCE IT Problem Solving Methodology Posters

Warning for maths people, you may want to ignore this post. ;) While maths will always be my first teaching love, I do teach a few ICT classes, including VCE Information Technology. A requirement of the subject is that all our work is based around a process called the 'Problem Solving…

Discrete Probability Posters

At the start of this term, I said I was going to make more of an effort to make posters and decorations, particularly for the video conferencing room where I teach Year 12 Maths Methods. That hasn't really happened as much as I'd hoped. But seeing all the new year…

Areas of shapes mini-posters

In my Year 9 textbook, the start of the chapter on area and volume starts with a "review" of areas from past years. And by that, I mean it says something along the line of "you should remember these formulas from Year 8," then proceeds to list the formulas for…

Differentiation Posters

I've never been that good at posters. In my defence (and take this for the lame excuse it totally is), my school doesn't give teachers their own room. My year nine and ten classes are in a room that doesn't have any spare space on the walls, my IT Applications…
