/r/matheducation

/r/matheducation is for discussions of math teaching and pedagogy.

r/matheducation is focused on mathematics pedagogy (the teaching of). Please avoid posts that are related to homework or other "How do I solve this?" type questions. There should be an emphasis on usefulness (such as good internet resources or ideas for how to teach a concept).

Note: This is not a subreddit to self-promote your blog, website, or YouTube channel, but rather to point out resources you've found that you could actually see bringing something useful to the art of math teaching.

Just explaining a single math concept isn't a good fit here, but something that explains an innovative way to teach a concept to others is fine.

The guiding principle for content here should be: is this something related to the teaching of mathematical concepts?

I know two different people who lived in central Pennsylvania. I would say they were in junior high in roughly 1990. They did not go to the same school and did not know each other, but they both separately mentioned a very unique way they learned math. I've tried to search for this online but couldnt really find anything conclusive, so I thought I'd bring it here and see if anyone knows anything about this method.

I dont remember all the details so I apologize if my mistakes make it harder to identify. Basically numbers were assigned names of generic items. So somehow you would memorize that 3+3 = pie in the face because 3 was substituted by mom (hold three fingers up and then flip them upside down makes an M). so two moms could make a pie.

Yes I know it sounds ridiculous. has ANYONE else heard of this lunacy?

I did Kumon in highschool and the practice helped me a lot. After a quick google search I can't seem to find a modern printable sheet generators online, many of the sites I found are older and difficult to navigate.

Would a more modern tool be useful for teachers/educators/parents? If so, which grades/subjects do you think would have the most interest? My uneducated guess is that basic number identification (e.g. count number of apples) and BEDMAS would be most popular since it's fundamental.

I’m trying to draft an IEP with math goals that cover all of pre-algebra, but for the life of me, I cannot find it spelled out anywhere. Basically I want the 7th grade IEP goals to state everything he needs to learn to take algebra in 8th grade. (Long story short, but everyone agrees that his math abilities should put him in 8th grade algebra, but he is having trouble focusing on the materials and completing work in 6th. So the goal is to get him the support he needs in 7th to get through the prealgebra curriculum.)

So where can I find a simple syllabus listing everything that needs to be learned in prealgebra?

School uses Illustrative Math and Zearn, but I cannot tell which grade level corresponds to prealgebra.

Dear all, My son is a academically strong 8th grade student that intends to do Calculus in 9th grade. He is currently enrolled in Geometry and Algebra 2 at a top public school, with straight As and no challenges. The math department has agreed to give him a chance to do Calc in 9th Grade provided he shows the completion of a validated Precalc course during summer. Due to a mistake from the administrative team, he won't be able to apply for the local University summer courses, as he originally planned.

I would like to know which courses would you recommend to fulfill this rather vague Precalc course requirement... many many thanks for any feedback you may give us.

Hi. I've got an interview coming up with Brighterly, and I'm curious to hear from anyone who has already gone through the application process or worked with them. What was your experience like? Any tips or insights would be greatly appreciated! Thanks in advance!

My grade 11 math teacher decided that he wasn't like those other girls. So he made my entire class do a math presentation as part of final exams. He gave us all a list of every type of math problem we did that semester and on exam day we would have to randomly solve one of them and explain to the class what we did. If we made a mistake, he'd stop us and either the first person to correct it would earn extra credit or someone who hasn't corrected yet. That was your way of earning your marks back, although sometimes he chose not to stop them and just nudged them in a direction.

I can't speak for my old classmates but I have a love hate relationship with this. Leave it to one of the schools coaches to make final exams--Math of all subjects-- a competition. I'm not a teacher but I'm very much curious what educators and other people think of this.

I just got accepted into Data Science programs at SDSU and UC Berkeley as a transfer student. I am very torn about which school to choose. Berkeley seems like it should be the obvious answer due to its prestige and how its is ranked as the number one data science undergraduate program in the US. But, if I went to SDSU I would get out debt free versus for Berkeley I would need to take loans out. Is the prestige of Berkeley worth going into debt for? By attending Berkeley would I land a higher paying job or get to work at companies like Google, Amazon, etc? Does Berkeley really give me a leg up in my career compared to a school like SDSU or does landing the right job come down to your projects and experience more in DS? Also, would attending Berkeley even matter if it seems like I am going to need to get a masters for becoming a data scientist anyways? Thank you in advance!

I’ve read the Wikipedia article on it and it says it’s been deemed one of the biggest educational failures of the 20th century.

Was New Math really doomed to fail because it was too hard for kids to comprehend, or was it more that it was too hard for teachers and parents to come to terms with?

I'm at University and the teacher asked to do a research on what are the difficulties math teachers experience when teaching deaf students, so I would like to know if anyone has something to share for my research. I would also appreciate if you could also say what did you do to solve this problem or if you couldn't solve it.

For context, my current students are under achievers, and new comers. I have, in my career, organized my math classes into 3 sections, instruction, examples, you try, rinse and repeat, depending on the section and length of class. At my current school that often means the you-try section is the last part of class, and my observation comments indicate that students doing classwork isn't considered keeping them engaged bell to bell. An additional wrinkle is that many students work and even if they don't, they don't do homework. I don't mind having classwork instead of homework, especially in this environment, but if this (given the circumstances) isn't bell to bell, what is?

I just got an offer from UNC today, and now I got accepted from TAMU and UNC for a math PhD. I know that TAMU is pretty good at functional analysis and mathematical physics. I’m wondering what the strong direction in would be UNC? And which one has a stronger faulty group if I’m willing to pursue in PDE and Analysis (not sure which specific direction of analysis yet)?

I'm quite handy with the (standard) Equation Editor in Word. I've taken a look at the Mathtype website, but can't really see what advantage the 62 dollar p/y tool will bring me.

Is there anyone who can shine a light on why I should (or shouldn't) get this Add-in?

Hi everyone. I have an obsessive personality and I have decided that my next one will be maths. I want to learn all of it but, to be fair, I suck at it. Nonetheless l am willing to make the effort. Can you please show me a path, some sources to begin learning above middle school level mathematics? Thank you.

Hi everyone,

I was wondering if somebody could clarify this for me: I know we have a complex exponential, but I am wondering if there exists a complex power function - or is it the case that the complex exponential sort of “covers” anything we would need for complex power function?

Thanks so so much.
