“There’s always a feeling of being excited, yet nervous; ready, yet unprepared for the unexpected; organized yet chaotic thinking of a million more things I could still do. But every time I see my why, I know I’m in the right profession.” I wrote this quote at the beginning of the school year and it […]

I made this quick activity for students to discover the exterior angle sum. I just printed several quadrilaterals and pentagons, cut out the exterior angles, and put them mixed up in a Ziplock bag. I gave students 5 minutes to work with a team of 3 to somehow figure out what all the angles added […]

My husband and I have been renovating our house (HGTV/DIYnetwork style, sadly without the help of Chip and Jo from Fixer Upper or Yard Crashers) and I realized it was the perfect opportunity for some real world geometry. The inside is almost completely done with a new kitchen and new flooring, so next we will […]

While planning for geometry last week I began thinking about how I could amp up midpoint and distance formulas. After learning the formulas, my students practiced with very abstract points. However, I knew I wanted them to see examples that had meaning. With the help of the English and World Geography teacher, I developed my students first interdisciplinary activity […]

I just finished the first week of school and looking back, it was one of my favorite starts to the year. Normally I’m not satisfied with my first day of school activities and either feel that they’re too cheesy or too boring. This year, however, I finally feel really happy with how the first day […]

My husband and I just got back from a great trip in Chicago to celebrate our first year anniversary. I loved every part of our trip from the delicious food, enjoying a no-hitter game at Wrigley Field, walking the city, seeing iconic sights, and so much more. Even though we were there for absolutely nothing to […]

Here is a quick lesson I put together using the Jigsaw Cooperative Learning technique for 3D solids. We learned the surface area and volume formulas for prisms in a direct instruction model and because we have such little time left in the year with testing and such, I decided Jigsaw-ing these concepts would be the best way. Overall, […]

A couple weeks ago, I was planning for our last unit in geometry which is 3 dimensional solids, and as I was measuring nets and counting vertices, edges, and faces, I suddenly realized I was really bored. If I was bored, my students definitely would be! I knew I needed to amp up my curriculum to still […]
