Geometry, Points of Concurrency

Concurrency in Triangles InfoNotes & Activities

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

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
