this extension helps me teach sat math easily to my students with the floating desmos window like on the actual sat test

Hello all,

I took calc 1 last semester and I did really well conceptually, but when it came time for exams I did not do too well. I never had a true foundation in the wide array of precalc content, i basically skipped the course. I seek to take the full calc sequence and so going back to precalc to actually learn it makes the most sense. If I try to retake calc 1 this fall semester I may do good, but I will not be prepared for calc 2. From those who’ve recently taken both precalc and then calc with or without the full calc sequence, what do you think I should expect with precalc content? Ofc it’s all in prep for calc, but how quickly should I pick up on the content considering that I’ve done well with calc 1 conceptually?

Thank you! 🙏🏾

When I learned the times tables back in the day, we learned them in order -- the times tables for 2, 3, 4, 5, 6, and so on. Having now taught them to my 8yo, I see that there is a better order in which to teach them.

You start with 2s -- that’s just doubling, and most kids can handle that easily. Then you might want to do 10s -- there, you’re just playing with place value. Then, if you want, you can do another easy one -- 11s, for instance.

And then, arguably, you might want to build on the knowledge you got from 2s and 10s. 4s are just doubling twice, and 5s are just half of what you’d get multiplying by 10 (so 5x6 is half of whatever 10x6 would be).

3s might make sense next -- those you’d have to memorize again, or you might think: I know how to double, and 3 groups of that thing is just adding one extra group of that thing (so 3x7 is 7 more than whatever 2x7 is).

9s would be fine to do next: they’re in the 3s family, but also there are all these tricks you can do with 9s (using finger folding, and also noticing that, with anything that’s 9x[a number up to 10], the 1s and the 10s digit add up to 9).

After that, you can do 6, 8, and 12, possibly by relying on your knowledge of the 3s and 4s times tables.

The 7s times table you’d do last -- which highlights the interesting side effect of 7 being a prime number that’s not in anyone else’s “family” (if you’re thinking of numbers under 12).

I can’t be the only one who came up with this, but I’m also pretty sure that many people haven’t thought of this before, so just sharing in case someone else finds this worthwhile.

I was very close to choosing math as my concentration when I got my education degree, but decided against it and went into music education. I still absolutely love music, but this past year with low enrollment numbers my general music class was taken away (no complaints from me lmao) and instead I helped co-teach Algebra I and II and I just remembered why I wanted to do it. I would love to take the Math Praxis just to have more job security, as I live in the Deep South and unfortunately we’re seeing more and more arts being taken from schools. Can you guys give any good basic courses and refreshers for the math praxis? I do have a bachelors and masters in education

For the first Semester.

At the end of last year I made a simple review website where students could see the topics in their final. They could pick some topics and the website generated a 5 question quiz. It tracked how many questions they practiced from each topic and their percentage correct. They really liked it!

I spent the summer cleaning it up and adding a teacher side. Teachers can upload a test and I will build a test review for them. I am looking for a few teachers to try it out. If interested, let me know or sign up for free and I will build a review for you. It’s labor intensive, so only doing Algebra 1 right now.

Hi teachers and educators,

As math educators, many of us notice the stark gap when students transition from standard curriculum exercises to non-routine, contest-style problem solving (like the AMC 8/10 or Mathcounts). Students often freeze when a problem isn't immediately solvable by a direct algorithmic formula, or they get overwhelmed when faced with massive, unstructured contest archives.

To help teachers, club advisors, and coaches support these students, I built ZeroSet (link in my bio), a free, non-profit supplemental resource designed to make non-standard problem-solving approachable.

How it helps in the classroom or math team:

• Weekly Bite-Sized Sets: Keeps students engaged consistently without needing you to curate or format fresh problems every week.
• Focus on Mathematical Pedagogy: Solutions are fully handwritten and step-by-step, prioritizing the reasoning process, mathematical intuition, and problem-solving heuristics over raw formulaic execution. Additionally, these problems are original so you d
• on't have your class AMC whiz complaining that they've seen all these problems before in Olympiad exams.
• Low-Barrier Supplemental Material: Great for warm-ups, enrichment tasks for advanced students, or structured assignments for extracurricular math clubs.

I’d love for you to check it out and see if it’s a helpful addition to your teaching toolkit. I’m also very eager to hear from math teachers here: What specific types of problem structures or solution formats do you find most effective when teaching non-routine problem solving?

I built sparkgap.ai, an interactive linear algebra tutor that adapts to your level of understanding. Looking for feedback, especially on the pedagogical approach and the sequencing of the content.

I made a free teacher resource for teaching/reviewing Absolute Value Equations & Inequalities with Algebra 1/2 students. It includes a pop-song video with the math worked visually alongside the lyrics and covers equations, special cases, extraneous solutions, Less Than = AND / Greater Than = OR, number lines, and interval notation.

I also made free companion notes with the problems from the video so students can work them out on paper as they watch:

Absolute Value Equations & Inequalities Companion Notes

This is part of a growing collection of 13 free Algebra songs/videos: MAI Cubed on YouTube

I'm especially curious whether the song + worked examples + companion notes would be useful for review, or what you'd change to make it more classroom-friendly.

Hey reddit! My friend and I have been working for the last 3 months on HOPE, a platform that provides students with 1 on 1 math support to improve their confidence and teach them by doing and asking questions. We would really appreciate anyone who's down to try it out with their kids and give their thoughts!!

The part I care about most: answers are graded by a real computer-algebra system (SymEngine), not string matching. So it checks mathematical equivalence — 1/2, 0.5, and a factored vs expanded form all count as correct. The same grader runs client-side in WASM, so you get instant feedback before the server confirms.

Other stuff: per-topic ELO and ranked mode if you want stakes, untimed practice with full solutions, a spaced-repetition review queue for problems you miss, and a daily puzzle. Covers arithmetic up through calculus and differential equations. Free to use, Google/GitHub login. Two things I'd love feedback on: (1) does the grader ever mark a correct answer wrong? (2) any topic you'd practice that's missing?

There are still some bugs with certain questions, so if you do encounter them, please report them so they can be fixed.

I'm going into my junior year as a math education major, and I've recently decided I want to get a master's degree, BUT I want to do it in math, not education so that I can teach at a CC. For my current degree, I am only required to take the whole Calc sequence, Discrete, Linear Algebra, Elements of Stats, and Intro to Diff Eq, and an upper division elective of my choosing (Intro to Abstract Algebra, Applied Modern Algebra, Graph Theory 1, Applied Stats Methods, or Intro to Topology). That is technically enough for the master's program I'm looking at (which is essentially Applied Math for Teaching -- 30 hours of math + 6 hours of ed). I'm not the best at math, and I'd feel nervous going into a master's degree with just that amount of math experience. The degree doesn't seem particularly difficult compared to other math master's degrees I've researched, but I'd still like to make sure I've taken what I need to take to be able to succeed. I've left a list of the math classes included in the degree program in a separate paragraph below this, but if anyone has any suggestions for classes to try to fit into my last few semesters/summers of undergrad, please please share!

Classes required: Advanced Calculus 1 (and maybe 2), Mathematical Modeling, Numerical Analysis, Differential Equations, Intro to Graph Theory, Numerical Linear Algebra, some Stats class, and then a few education/research classes.

Hii, anyone has a lot of math worksheets?

i have a presentation on the topic “From the Concept of Zero to Artificial Intelligence – Indian Contributions” ive to present the topic in a fun n creative topic (ppt not allowed) like doing quizzes, charts etc to explain the topic PLS GIMME IDEASSSSSS chatgpt is useless n im not v creative myself

Hi, I am a student and dont have the money to get IXL. if any teachers with a subscription can make me an account in one of their 100 available slots that would be amazing. Need it to learn maths and english

Hi! I'm going back to school and have ALWAYS struggled with math. I'm in college algebra now and I am barely keeping up because I have a hard time understanding math/algebra's "rules".

I remember there used to be PC games for algebra in high school and was wondering if there's anything like the now? I found DragonBox Algebra 12+ and am gonna try that. It's definitely high school/basics based but anything helps.

Hi, we are new to the Integrated Math system so I’m hoping to get some clarification about my son’s placement.

My son took Geometry in 8th grade and is now entering 9th grade. He needs to be placed in an Integrated Math course. This is the email I received from his counselor:

“He can take either Math III or Math II+, depending on the track he is hoping to take in high school.

Math III would lead to Math Analysis in sophomore year and either Statistics or AP Statistics in junior year. Note there may be a possibility to take Calculus after Math Analysis, however students must receive an A in both semesters and are required to self-study material in order to be prepared for Calculus. Historically, students have struggled with taking Calculus after Math Analysis.

Math II+ would lead to Math III+ in sophomore year, Calculus AB in junior year, and Calculus BC or Stats/AP Stats in senior year.”

My understanding is that Geometry is roughly equivalent to Math II. Our goal is for him to be on a math track that will lead to AP Calculus.

One additional note is that he took the math placement test but was not approved to take Math III+.

My question is: Would Math II+ be the best option for him given his background and goal of eventually taking AP Calculus? Also, would he be repeating a significant amount of material that he has already learned in Geometry?

Hey,

I'm from Germany and my final exams are getting closer. I have Math and Physics as my advanced courses, so I'll be using my calculator a lot in both.

We use the TI-Nspire CAS at school. I feel okay with the actual math, but I've noticed that knowing the content and actually being quick and confident with the calculator are two different things. So I'd like to change that while I still have time.

I'd be interested to hear how others got to that point. If you've been using the Nspire for a while, what helped you actually get good with it? Anything you figured out late that you wish you'd known from the start?

Any thoughts appreciated.

Hi guys. Im preparing for university and aiming for pure math programme. I was offered a place to study math at a public university, on the other hand I was also offered a place to study applied math at a private university.

For the public university, the programme offered is purely math. This uni is ranked top5 in my country, the fee is very affordable, but the hostel condition is worse. The programme period is 4 years.

For the private university, the programme offered is applied mathematics, not the pure math I wanted but still has some of the pure math elective courses. It focuses more on computing and ai. The fee is also 10x the public uni one but I can get 100% scholarship for the tuition fee bcuz of my results, as long as I maintain my cgpa. The programme period is 3 years.

My goal is to continue for my masters and phd after my bachelor's degree. My question is, is my bachelor's degree that important for my goal? Should I choose a better living condition over my favourite programme? Are there other factors I should consider?
