I usually teach points of concurrency before Winter break but since I'm doing the Building Thinking Classrooms (by Peter Liljedahl) I'm not moving quite as fast and I'm okay with that. My students are gaining a deeper understanding and on their semester 1 reflection, many of them said they like building their understanding at the… Continue reading Concurrency in Triangles InfoNotes & Activities

Graspable Math
I attended Howie Hua's #VirtualMath21 (you can search the hashtag on Twitter but Howie seems to have disabled his Twitter account). I really enjoy a good free conference and this one didn't disappoint. I have a few things churning in my mind, but one I wanted to share immediately was Graspable Math shared by Tim… Continue reading Graspable Math
Get a Clue Escape Room
We are not giving finals this year. An idea I think I support (it has been hard keeping motivation without a final). I wanted a way to review everything we have learned this year but in a fun way. I originally planned to do a murder-mystery activity like I saw on Twitter shared by @MrsHiltnerReads.… Continue reading Get a Clue Escape Room
Commercials for Class
As the year winds down, keeping the excitement going is sometimes difficult. I have two classes with seniors, whose last day was Friday, and now I have Juniors for 2 more weeks and I need to find activities to do that do not rely on new content. I decided to make commercials for students in… Continue reading Commercials for Class
Go Fly A Kite
My colleague and friend, Danyelle, has done this kite construction project for a number of years during summer school. She first saw it at a conference many years ago. We decided to try it last year during the school year and then the pandemic closed school and we didn't get to do it. When the… Continue reading Go Fly A Kite
Similarity Exit Tickets
As promised last week, here are some exit tickets that you can use with a Similarity Unit in Geometry. Just a reminder of how I use these. I give feedback on each submission and have students work on them until they are correct. I love doing this with the comment feature in Google Slides. In… Continue reading Similarity Exit Tickets
Road Kill Kafe goes Remote
Well that sounds like a movie title. I wanted to share with you a quick update to Road Kill Kafe that I use in my Geometry class to discover congruent triangles. It was shared with me by my friend Craig Klement (@CraigKlement) and you can read about all of my Triangle Congruence activities here. We… Continue reading Road Kill Kafe goes Remote
Volume and Spheres Application
Installment three of the area, surface area, and volume application problems. I know some of you have been using these and I hope they are working out well. Area application can be found here. Surface area application can be found here. In this post I have included volume application problems and application for surface area… Continue reading Volume and Spheres Application
Creating Popcorn Containers
I love taking boring problems from the book and turning them into fun learning experiences. A boring word problem was the beginning of this task. The actual prompt (which I can't seem to find anymore) gave two popcorn containers, one a cylinder and one a cone, and asked the relationship between the volumes. I saw… Continue reading Creating Popcorn Containers
Application for Surface Area
I posted some area application problems last week. You can find that post here. I also promised some surface area problems, so here you go. One page is many different problems that you could use as an assignment, assessment, or problem of the day. The second one is one problem broken up into 5 days,… Continue reading Application for Surface Area
