Introduction to tips on how to use Algebra Tiles. These tiles, the “base ten blocks of center college” are the go-to device in any good algebra trainer’s arsenal.

You could have heard his voice within the wildly standard online game, 5 Nights at Freddy’s: Sister Location.
Earlier than turning into a voice actor, Mr. Area was a center college math, science, and STEM trainer, and taught elementary arithmetic strategies on the College of Mississippi.

Why does X always ≈ 5.2?
Fans of Algebra Tiles cheat and say (as here): "Since the length of the X bar is not divisible evenly by the 1×1 squares (it's not exactly 5 or 6), we're going to pretend that means, 'Unknown' ".
This exception is presented slickly as if it were a "rule". It is NOT a rule. It is a PROBLEM WITH THE SYSTEM.
If it is a rule, then does this mean that whenever we get a fraction in our future math lessons, we can call that an X?
There are many other issues as well, some minor, others major. (Why are positive numbers using different colors for different sized tiles, but negatives are all red? Is this significant? Or not? Also, when using AT's with equalities (equations on both sides of an equals sign), certain manipulations (movements of the tiles) are "legal" under the system, and other manipulations/moves which are more intuitive to a young mind are actually illegal.) All of these factors are "dirty", rather than presenting a "clean" system to a young mind. Finally, when one tries to use AT's for more and more advanced concepts, the more exceptions have to be introduced, as well. By the time the system becomes completely untenable, it has to be abandoned.
Algebra Tiles is an ugly (inconsistent) system whose proponents ignore the exceptions and problems, even when these problems are pointed out to them by other adults. But forcing young minds either to load this clutter into their heads, or (for those who SEE these problems early on) to sublimate their good seeing and play along — these are even uglier.
nice what a legend
Thank you this was a clear explanation
Wow, what an inspiring math teacher! I sure hope he doesn't become the comic relief voice actor in a popular game series about haunted robot animals!
HI MR. ANDY!! I HAVE A GREAT TEACHER THAT WAS MY MOST IDOL!! HE TEACH ME ARCHITECTURE AND I LEARN SO MUCH FROM HIM.. HIS NAME IS ANDY TOO!! ANDY ARE GREAT PEOPLE THO!!
Yo I didn’t know the legend was also a mathematician NOOOOIIICCEEE
How can you have negative X squared? I am wondering this because if you take a negative number and multiply it by itself you get a positive number, and if you square a positive number you get a positive number. e.g -2*-2=4 2*2=4.
Yo you need to be my teacher but in high school
Great intro to algebra tiles!!!
Hi
anyone from ms s's class here?
I look at this dude and all I see is the bald head and the american flag. Its awesome. He also teaches really well and I understand this much better now.
Yeah… that did not in fact explain how to use the tiles. That was a starter about what their value is and I still think they're a bad idea.
Nice vid I am in 8th grade and started school a week ago I wanted to learn about dis to prepare for the test
I'm not a fan of these new approaches to math, but I appreciate your video since it stated the assumptions one makes (e.g. the smallest squares are unit squares) that weren't stated in my daughter's math book. So many sources and videos fail to point out the basics. Thanks!
Hello! Would you tell me how you set up your device to record your videos? I am a teacher and I do tutoring online. I send videos to my students all the time, but I can't find how to set my device so it's comfortable for me and it visually clear for my students. Please help as soon as possible.

I can't stand algebra tiles…absolutely no offence to you teaching,but I'm in grade 10 and was never taught this till this year. I understand if you give me an equation,but all I see are boxes and squares and they freak me out!!! and I have a moth provincial in 3 days and I'm freaking right out!!!!
idk y i laughed so hard at this XD
lol
Forget the haters. This video was very helpful. I also teach 7th grade math and need to learn how to use tiles.
I gave you a thumb-up. I'd say "thumbS-up", but in reality it is only one thumb; I only get one vote. I'm in my second semester of student teaching and looking at the new common core textbook we'll be using, filled with algebra tile stuff, which I'm not really good at. I'm scared to death! I think I'm going to plow through this without using the tiles….?
