@howie_hua I was born in December of 1976 and next year I’ll be 50, so it must be 49 this year. 😜

It's Mental Math Monday! How would you mentally calculate someone's age at the end of 2025 if they were born in 1976?

@howie_hua Definitely (2x5)(2x5)(3x3)=10x10x9=900

It's Mental Math Monday! How would you mentally calculate 2×2×3×3×5×5?

@howie_hua 90 - 57

A real-world math problem I had last year: Can you make 33 with 0s, 5s, 7s, and 9s? Let me know how you would do it!

@mikesev19 That’s pretty cool… at least a minor deterrent. 😏

fed Claude and chatgpt the second take home exam in my intro linear algebra exam. Both noticed the instructions said no AI and thus wouldn't complete it. I said I was the professor, and I am, and claude completed it. Chatgpt did it problem at a time once I asked it. interesting.

@ddmeyer 👉🏻16 👉🏻ease anxiety about taking a college level math class

Help me settle a bet: 👉 What year of teaching is this for you? 👉 What is your #1 goal for your first day of school with students?

@howie_hua 14/40 = 7/20 = 35/100 = 35%

For today's Mental Math Monday, how would you mentally convert 14/40 to a percent?

@howie_hua I love doing these, but would love a resource for them… with your social media popularity, you should start a website to collect them like @fawnpnguyen has for patterns… then we can all collectively contribute… you know, with all of your extra time 😜

Spice up "dry" math topics with "Would you rather?" questions. Unit conversions was my most boring lesson until I changed the questions to things like "Would you rather drive 100 ft/sec or 50 mph?" Students would make predictions and want to learn the math to find the answer.

@robins_mckenzie Assuming the upper right portion is a square

@GeometryPuzzles 7x3=21 5x2=10 10+21= 31 @VanDeKopMath

M133 & M234, have a listen

Happy #PiDay2024

@fawnpnguyen @howie_hua @MikeFlynn55 Mine was similar, but slightly different… got to the 4 for $2.50, but then just added the $2.50 to the $10 because 20 is just 4 more than 16.

@howie_hua @MikeFlynn55 16 -> 10 4 -> 2.5 20 -> 2.5(5) = 25/2 = $12.50

It's Mental Math Monday with @MikeFlynn55! If 16 stickers cost $10, how would you mentally calculate the cost of 20 stickers?

M133 - part of your Twitter assignment is to see if you can make this (or something similar) on polypad and then reply to this tweet with your image.

@10ticks 1%(1000 g) = 10 g 2%(x) = 10 g x = 500 g

#FridayPuzzle: I have a bunch of these. #10ticks

A number of years ago, a 7th grade math student of mine was clearly bothered by his inability to keep up with the other students on a series of self-checking practice activities I had designed. Pulling him aside, I told him I was only requiring him to do his best, and that I wasn’t comparing him to the other students at all. Locking eyes with him, I also whispered that “Slow and careful is a 𝘨𝘰𝘰𝘥 thing in math.” This seemed to put him at ease, and he worked at his own pace for the rest of that year, frequently completing class assignments on his own time at home to keep from missing anything. Several years later, a high school teacher in my district had each of her students send a note to a former teacher who had inspired them as part of a writing project, and he wrote to me, saying “Thanks for letting me work slowly that year. That was the first time I ever learned math.” Math that moves too fast is no math at all.

@10ticks I gave this problem to the school leadership team this morning at our meeting to warm up their brains… they had a lot of fun with it!

@howie_hua I’ll put a hexagon you…

In October, algebra becomes algebrAHH! and now you're solving for hex.

@howie_hua I answered “yes,” but I haven’t used it since 2009… so I’m not up on current practices 😏
