Today, my math peeps, we’re going to be sharing and maybe doing math! Is there a problem that you love having your kids work on? A favorite problem that evokes conversation and ah hah moments? Or is there a math problem or puzzle you’ve seen or done that made you go “oh, wow!”?  In your Mastodon post: 1. Write down your math problem! If you use it in your class, share the grade/class you use it with, and why you like the problem for your kids. If it’s just a recreational math problem or puzzle, feel free to just drop it in the post. You can decide whether you want to give a hint or not ..read more

Recently, Sam Shah and I decided to join Mathstodon and try to rebuild our math teacher community. I have been so excited to talk to all of my math teacher friends again! It truly feels like Twitter 2010, 2.0. We also started a new hashtag, #ClassroomMath, so we could easily find other math teacher posts. There are already about 100 posts a week to this hashtag, so join in our fun! ColinTheMathmo made a very cool Solipsys that created a visual of the conversations recently happening. I love to try all of the things, so I’ve been downloading different mastodon apps for my phone. I’ve tried Mas ..read more

(From Sam Shah and Julie Reulbach) What We’re Doing and Why: Okay, friends. Twitter was acquired by Elon Musk and seems to constantly be on the brink of imploding and full of misinformation, and now ads about every three tweets. There is that whole pandemic thing where many of us were just trying to keep our heads above water — and so we connected less with the online math community. Twitter Math Camp became a thing of the past. And blogging was already on the decline.  And you know what? We miss our math teacher community so goshdarn much. We miss talking with each other, throwing lesson ..read more

20 Minute Assessments
I Speak Math
by I Speak Math
1y ago
Last year, I decided to make all of my assessments 20 minutes or less, even in my AP Calculus classes. My school created a post covid schedule, to reduce stress for students and teachers. In this schedule, students had three 70-minute periods a day. Since we had 6 total periods and a “drop day” each rotation, some weeks I saw my students three days, and some weeks I only was able to see them twice for class. The schedule was wonderful for everyone’s mental health, but it did significantly cut down class days. As an AP Calculus teacher, this was concerning. Because, excluding the month of April ..read more

Using Delta Math to See 3D Volumes
I Speak Math

2y ago
Delta Math has incredible sets for seeing volume of cross-sections and solids of revolutions. If you instruct your students to click on “show solution“, they can pull a slider to see the region become a solid! For the cross-section set, it shows the shape (square, rectangle, or triangle) growing along the base. For the disks, it includes the radius with the 3D shape. The washer set shows the washer inside the 3D shape. There is also a matching set, where students can practice matching up the 2D region with a resulting 3D shape, and vice versa. The five sets I use are in the image below. I have ..read more

Discovering Volumes of Known Cross Sections Using Play-Doh
I Speak Math
by I Speak Math

My AP Calculus students had a tough time with volume last year. So this year I wanted an activity where they could actually see the cross sections. I have seen many awesome activities where students actually measure the base between curves, and then create cross sections using paper, like the ones from Bowman and Rebacka. I would love to do these with my students, but unfortunately we are very short on time this year because of our school schedule. So, I decided to try it out using Play-Doh. I had students mold each type of cross section, and then let them slice it with either dental floss or ..read more

Feeling Depressed Teachers? Try One Good Thing

“The negative screams at you, but the positive only whispers.” Barbara Fredrickson Most of my Facebook and all of my Twitter friends are teachers. And I have seen so many posts that tell me that my teacher friends are not ok. Teachers are overwhelmed, overworked, stressed and sad. Well, in none of the posts do teachers actually say that they are sad. Instead, they say they exhausted, lethargic, and talk about the lack of motivation. And I have been feeling many of these same things, especially the lack of motivation in this very cold winter. I am sad, as I am every January and February. But I ..read more
