The locus of all points equidistant from a line and a point not on that line would be a parabola (but you already knew that if you had seen this earlier post!). For example, the locus of all points equidistant from a fixed point would be a circle. A locus is the set of all points satisfying some condition. Hmm, maybe there is something to these crazy conics after all….Īs my Precalculus students begin to explore conic sections, a related activity that is a lot of fun is to use the concept of locus to generate them. They got very excited as they saw their function plots match the photos so closely. Then, we pasted the photos into Geometer’s Sketchpad, placed a grid over them, and came up with functions that model each conic section. We took photos of the water coming out of a drinking fountain, the fireplace of our school’s library, and a flashlight’s beam when it is next to a wall. So, as my precalculus students wrapped up their investigations into parabolas, ellipses, and hyperbolas, we looked at some examples of how they occur in the real world. That said, I do try to make connections between abstract mathematical concepts and things my students encounter in their lives. I wonder if my colleagues who teach literature have to deal with that! Of course, math is worth studying in and of itself, just as poetry is. Have a great week.How many times have math teachers heard that question? I question the assumption underlying it – that math should only be learned if it has “real-life” application. Many of the websites are pdf’s and word documents, but there are several Geometer Sketchpad files included in the mix.Īs always, I would love to hear of other sites that would be a good addition to my list.

Targeted Implementation and Planning Supports – This website provides a series of lessons for Ontario Curriculum topics in grades 7 through 10. It also includes tutorials and information about the program. Hastings and Prince Edward District School Board – Provides a variety of Geometer’s Sketchpad resources and lessons for grades 2 through 8 – a great list. Offered by the makers of the program, Dynamic Geometry, this site includes information about the program and its use around the world, various classroom ideas, projects, a Sketch Gallery provided by users, links, PD information, and a downloadable how-to guide. The Geometer’s Sketchpad Website This should be your starting point. For those of you who are already using it, here are a few websites to help you along: I have not spent much time exploring Geometer’s Sketchpad, and I have put it on this summer’s “to do” list. Posted by admin in General Science, Math, 0 comments (Update – This section no longer appears to be part of the website) Here is the resource that I found which uses Geometer’s Sketchpad to help teach slope concepts. Once on the correct school section, there are a variety of math topics with lesson and unit plans to explore. The section is titled “Concept Development Units”, and the right side bar allows you to choose elementary, middle school, or high school. Finding the education section was a bit tricky and wasn’t easily accessible from their main page, but I managed to find the right area. I was surprised at the source, and so I went to their main site to see what other type of resources were available.

One of the documents that came up in my search was a pdf from NSA website. The second site was found as I was exploring creative ideas for teaching slope. If interested, here is the resource I found for solubility (which is actually only a small part of this resource). The e-library is definitely the place to be on that website, where you can search their vast resources by topic, age range, type/format, publisher, or year. According to their website, they house “the UK’s largest collection of STEM and teaching resources”.

I was searching for solubility animations when I came across the National Stem Centre.

This week I came across two interesting educational resources, the National Stem Centre in the UK and surprisingly, the National Security Agency (who knew?).
