I’ve mentioned the ice cabinets at this chain of convenience stores before. They provide some nice data points for a linear relationship. I finally built a short Desmos activity around the photos. Even though the short activity could be polished, it has a couple of nice features on slide #3 The user is prompted to enter an equation, and the… Read more →
Region 4 Educational Service Center hosted their annual Math Conference, and they usually offer a handful of sessions addressing students with special needs (EL students, students with IEPs, struggling learners, and more). This year, I attended a fantastic session by a new presenter, Leximar Irizarry. The heart of Ms. Irizarry’s session was a cluster of five stations that attempted to replicate… Read more →
I once fixed a broken cruise control on my SUV. I used an internet search engine to look up the specific problem I encountered, I found the exact part number to order from the dealership, and a couple of online videos gave me step-by-step instructions on restoring everything to working order. Of course, I still know nothing about how cruise control… Read more →
Meet Taco, my trained snail. I give him signals, and he walks up and down a tree in my backyard. If you’ve worked with integer tiles, you can see some quick connections. The yellow commands look like positive integer tiles, and the red commands look like negative integer tiles. After students experiment with Taco the snail, they are ready to… Read more →
We all stumble across moments or images that would make for great math explorations. For example, every time I stop at Buc-ee’s I photograph the cabinets of ice for sale. Someday, I am sure I will make an interesting activity predicting how much a bag of 30 pounds of ice should cost. On a recent trip, however, I discovered that… Read more →
A few years ago, I was talking with a teacher on my team, asking him how he coached students who struggle with word problems. His toolbox of problem solving pedagogy boiled down to one sentence: “I tell them to read the problem again.” While it is vital to make sure students understand the problem, we can help them develop strategies… Read more →
Two of last week’s sessions at T3 in San Antonio highlighted some great strategies to differentiate for Special Education students using TI Nspires and TI’s Navigator teacher software. Andy Aguirre, from Northside ISD’s new Harlan HS, share very practical strategies for differentiating a TI Nspire activity to meet the needs of different learners. She began with a .tns file from TI’s… Read more →
The first two weeks of this school year, I have been teaching a Geometry course for 8th graders in a face-to-face/distance learning hybrid. My students were spread across several campuses. I would physically teach from a different campus each day, which students from other campuses would join us via teleconference. My biggest concern as the first day of school approached… Read more →
We just completed the first week of school, and I taught a middle school Geometry course in a distance learning/face-to-face hybrid environment. My students were spread across several campuses and I physically taught the class from a different campus each day. This allowed the students to have face-to-face class time with their teacher on the days I visited their campus,… Read more →
My oldest brother earned his undergraduate degree in astronomy. He puts it to good use. He studies space weather and helps design components for satellites. Sometimes we end up in remote locations with great views of the night sky. He enjoys pointing out some highlights: “The International Space Station should be visible near the horizon in view minutes over that… Read more →
