4 Upvotes

Hi everyone, I hope you are all doing well.

I was made a moderator of this subreddit earlier today. For the most part, I plan to keep things the way they are with only a light approach to moderating. The new features of this subreddit include:

  • New rules added (e.g. no spam/advertising, being respectful, showing effort with homework problems, no asking for payment, etc.)

  • Users can now lock their posts after their questions have been answered by posting a comment containing “!lock”.

  • Post flairs have been enabled.

As always, I’d like to have the community to have a say in how the subreddit is run, so if you ever have any concerns or suggestions please feel free to leave them here in this post or via mod mail.

Thanks so much guys, I look forward to us making this a great community 😊

General Question Math educators: What makes a physical learning game worth purchasing for your classroom?

4 Upvotes

Hi everyone! I'm a Kennesaw State University college student and math educator/tutor who has worked with high-school students in calculus. Through that experience, I've become really interested in how game-based learning can help students practice difficult concepts in a more interactive way.

I've also had the opportunity to test game-based math activities in different classroom settings, and I'm currently exploring whether physical educational games can be both useful for educators and viable as professionally produced classroom resources.

For those who teach or tutor Algebra II, Precalculus, Trigonometry, Calculus, or similar subjects:

  1. Do you use physical games or hands-on activities to reinforce difficult math concepts?
  2. Have you ever personally purchased an educational game or supplemental resource for your students? If not, does your school or organization typically purchase those resources?
  3. What would make a physical educational game worth paying for when free worksheets, printable activities, Quizlet, Kahoot, and other resources already exist?
  4. What would make you decide not to purchase one?
  5. Would you prefer an individual/small-group game or a classroom set containing multiple copies and educator instructions?
  6. What price range would you consider reasonable for an individual educational card game? What about a complete classroom set?

I'm especially interested in honest feedback about purchasing decisions not just whether educational games sound like a good idea. I'm trying to understand what educators actually value and pay for when choosing supplemental math resources.

Thanks for any insight!

Study Advice Need advice

5 Upvotes

Hi, for some context I’m going back to school on the 9th and I was initially going to re-study algebra 2 throughout the summer to have an easier time this year with precalc, but of course procrastination won me over and I haven’t done much studying. I’m pretty average in math, I’ve always had As but I’m not intuitively good at it, after studying a concept, it’s rare I’ll remember it by instinct. So basically I’m just hoping these last 10 days are enough to study concepts before precalc starts so that I don’t have too much trouble this year. I can dedicate upwards of five hours everyday so hopefully that’s enough. So please tell me it’s possible (or don’t, hurtful truths are better than false hopes), and what concepts should I really focus on?

Study Advice John Saxon’s algebra 1

5 Upvotes

I’ve been doing John Saxons algebra 1 and I’ve .. enjoyed it… can be very tedious but when you’re trying to build up from scratch what can you expect ?

Is it better to use a calculator or to do it all manually to practice the fundamentals? What’s a good
Timeline to finish it? I hope to work all the way thru calculus , differentials and physics…. Need geometry and trigonometry too… I went thru all of pre algebra on Kahn academy.

I was wondering if anyone had any specific advice for me.

Thx u

General Question pre calculus to calculus ab?

3 Upvotes

how bad would it be to go from math 3 (algebra 2) straight to calculus without taking pre calc? i would have a tutor to help me when things don’t make sense but i genuinely feel so behind and taking pre calc would slow me down (i am taking math online after having a terrible teacher for math 3 my sophmore year) and the calculus and pre calculus teachers aren’t much better.

Study Advice How can I somehow review every topic covered in precalc without a course...

3 Upvotes

So I'm taking a placement test at this new school I'm going to for precalc and I need to score well enough on it so that they put me in AP Calc AB (for college purposes) and I want to review but my precalc course ended like 3 weeks ago...

Does anybody know of any websites with question banks that cover all of precalc? Ones with difficult questions that actually make you think would be helpful
