This curriculum is based on a schedule with 50 minute classes. Here is a Google Drive folder with every handout, another folder with an answer key for every handout in the first semester, and a video playlist showing how to create visuals in GeoGebra. Also, many problems throughout the curriculum, including all multiple choice questions, are released items retrieved from ACT, New Visions, PARCCPSAT, SAT, and TEA. Finally, check out the pedagogy page to see snapshots of how to implement these lessons.

25 thoughts on “Geometry

  1. I teach algebra I and geometry. I found your website when looking into standards based grading this past August. I liked your format for SBG, and looked at your curriculum. I have been using it this year, with some minor changes. I really like the geometry and how it is flowing. My students have been learning about parallel lines crossed by a transversal, and I’m about to introduce proofs. I’m excited to do this with the mazes! Thank you for sharing all of this. I know you’ve put a lot of time and effort into it. It’s nice to find so many great resources in one place.
    I’m using some of the algebra work, but had to slow it down a little at the start. Most of my students weren’t ready for where your curriculum started. I will keep using resources from your curriculum, though, and I’m following your units and quiz techniques.
    Once again, thank you! !!

    1. Sarah,

      Thanks so much for the kind words! I really appreciate it. I’m glad it’s been useful so far! This is my first year teaching Geometry, so it’ll have to be adjusted over time. If you don’t mind sharing, I’d love to hear about/see some of the changes you made! Feel free to reply here or email me if that’s easier.

      Thanks again!

  2. I just stumbled onto your blog and am blown away! Thank you so much for sharing all of this. You’ve clearly put a lot of time and energy into it. You rock!

  3. Hey Dane,

    You mentioned before your school’s resource is Big Ideas….Do you ever use the Student Journals or Textbooks for anything during your lesson’s or for homework problems outside of class?

    1. Hey Jake,

      I mainly use the book to find more challenging questions and to help guide the order I teach topics. I don’t use student journals. Everything on the curriculum page here is what I give in class. I don’t give homework. Thanks for the questions!

      1. I appreciate your response! Thank you very much. Again, I absolutely love what you have done with the Geometry curriculum and I am going to try to follow this model and use what you have! I’ve looked through just about everything and love how you engage the students and work through lots of different activities throughout the class. I like how you do ungraded formative assessments to see where kids are at, I like the spiraling idea, and I really like the concepts quizzes and how it relates to standards based grading. Last question….If I use all of these resources this coming year in my geometry class should I be making copies of all the google docs and keeping them in my drive so I have them and I know they won’t change? I ask that out of fear of losing the documents because of things that get changed or deleted or if for some reason the site ever went away and I didn’t have access to these materials halfway through the year all of a sudden and I haven’t made my own copies in my google drive. Any thoughts on that?

        Also I am REALLY looking forward to see what you end up doing with Algebra, as I see it’s a work in progress and lots of links are under construction and being edited. Do you plan on updating that throughout this school year by chance?

      2. Thanks so much again for the positive feedback, Jake! It really means a lot. Although I don’t plan on getting rid of the site at any point, it may be a good idea to make copies of the documents because I usually update them here and there each year. I’ll always have the docs posted, but the content may change depending on student needs or new ideas. Also, I am planning on updating the Algebra 1 materials throughout this school year. It’ll probably be a slow process.

    1. Hey Stephen,

      I covered quadrilaterals on days 100-104. However, that is a unit that I’m thinking about tweaking. This curriculum was based on my first year of teaching Geometry, so I’m still learning! Thoughts on what should be changed?

  4. Hey Dane,

    I love your website! Do your students have access to this website or is there a separate website that you give to your students?

  5. Dane,

    I noticed that sometimes you don’t include concept quizzes that cover material taught. For example, segments of circles seem to not be assessed. I assume there is a good reason behind it though. I would appreciate it if you could explain to me why so I can have a deeper understanding of your thought process behind teaching material and concept quizzes.

    Thank you,
    Kevin Grogaard

    1. Hey Kevin,

      Thanks for the question. When planning out a course, I try to choose the 20 most important concepts (based on state standards and feedback from teachers on my team and higher level content areas) to assess. From there, I spend the bulk of our time teaching those top 20, and I only quiz those top 20. Here’s a detailed breakdown of why and how to do this. The segments of circles unit was a tough one to determine whether or not to quiz, but I decided not to because it seemed too reliant on formulas (at least from my new to Geometry teaching perspective). I decided that I didn’t have enough time to go as in-depth as needed for a quiz, so I taught the basics and moved on to more important topics.

      Hope that helps!

  6. Hey Dane, I started implementing some of the online activities in my class and they have gone great! I was wondering if you touch on the centers of triangles at all (orthocenter, centroid, circumcenter)?

    1. Hey Stephen,

      Thanks for the encouragement! I’m happy to hear that they are going well.

      In our state, points of concurrency is not in the standards, so I left it out of the curriculum. However, I did teach it a couple years ago, and here are the lessons. It didn’t seem to flow well, so look through them with caution.

      Let me know if that helps!

  7. Thank you soooo much for all your hard work! You have made my life much easier. I was wondering if you have a Google drive for Geometry like you do for Algebra.

    1. Thank you for the kind words! I’m glad the site is useful. At this time, the Geometry Google Drive is a work in progress. Unfortunately, it probably won’t be ready until the end of this school year.

  8. I’m a first year teacher and you have lit up my life with these problems. They are everything I was looking for and aspiring to. I also love that I can teach them in my own way.

    Thank you from Seattle!

    1. Wow, thank you so much for the kind words, Maddie! I really appreciate it and am glad the site has been useful. Feel free to send questions or feedback for improvement any time.

      Good luck with the rest of the school year!

  9. This curriculum is amazing, thank you!!! It’s saved me as a new Geometry teacher!!! Do you have a folder or document with all the geometry problems you’ve pulled from from ACT, New Visions, PARCC, PSAT, SAT, and TEA?

    1. Thank you for the kind words! I really appreciate it and am glad the site has been useful.

      Unfortunately, I do not have a folder or document with those problems. I used to, but I got rid of them once the problems were placed in the curriculum. Sorry about that!
