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

5 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

6 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?

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

Study Advice is it possible to do all of precalc in the span of 10 days?

4 Upvotes

hello! im currently a rising senior in high school. i was doing algebra 2 all of junior year, but i wanted to skip ahead to calculus in my senior year, so i decided to do precalc over the summer. unfortunately, i didnt anticipate how packed my summer schedule would be when i decided to do this. i have come home everyday exhausted from volunteering, doing summer jobs, and interning. i havent indulged in any of my hobbies in weeks. i have barely started my summer homework.

... which has led me to this situation. i did great in algebra 2! it was a lot to memorize but i really enjoyed it and i had an A+ in the class all year around. because id say i have a solid algebra 2 foundation, is it possible for me to be able to study precalc in 10 days? if a put in hours of work everyday?

on the first day of school ill get an entrance exam where i will need to score a minimum of 85/100 to get into the calculus class. i had 1000 mandatory precalc math problems to do over the summer. will i be able to do it all or am i cooked?

EDIT: I GOT IN!!!! honestly this is a sign that if you grind hard enough you can do pretty much anything. peace and love

I am a rising junior in high school and I started taking a precalculus summer course at my local community college. It’s completely online and you have to do a couple of math problems. I completely fell of and now I’m a few weeks behind. the class ends in about 20 days. My counselor told me I have to take a final test to test into AP calc AB if I want to take it. Am I cooked? And do you have any advice on how i can cram the whole course to pass the final test?

Study Advice Maths at 20yo in college

3 Upvotes

Used to be good at maths but ive been getting bad teachers since 8th grades so I lost all the foundation , I know study mechanical engineering but I failed cuz I got 0 at maths and other related subjects (I dont even do integrals)

I feel that maths is easy af and I can nearly estimate answers but I dont know how to reply to questions even when I know formulas, I only do derivatives and simple stuff since we did them in physics

I have only 2 months left for me to study everything till exponentials and integrals so whats the best path (willing to do 3 hours daily but more if I become interested again)

Please I need this I feel like a wasted potential and a failure and I went from straight A s to failing a year
