Helping people learn and teach math, Singing in choirs for fun, and Solving Tech Problems in Summerside, Prince Edward Island, Canada

In Toronto, I helped hundreds of students through high school & university as a private tutor, teacher, academic advisor, school administrator and guidance counsellor. I co-founded and ran a private, alternative high school, then established my own math tutoring centre. I used several stylus-based tablet PCs for taking/making digital math notes long before tablets were a thing. I was also an active volunteer in the Ontario homeschooling community: writing, advising, and speaking at conferences.

From our island waterfront "semi-retirement" home in Atlantic Canada, I currently create and sell middle & high school math teaching/learning resources. Although I taught high school and intro university mathematics, the real need in education is to support teachers of earlier grades who may not be math specialists themselves and whose own backgrounds and/or confidence in math may be lacking. My most popular products are those that thoroughly and thoughtfully explain "the basics" such as integers and solving simple equations.

I also write about my experiences in tech as a power user and floundering app-builder/tech-learner. (Just what is Error 28, anyway?)

I happily sing the least-conspicuous Alto2 lines in as many local PEI choirs as our travel schedule permits. I'm Communications Director & General Tech Support for the Summerside Community Choir, and Choral Librarian for the Indian River Festival Chorus. When not rehearsing, I can be found digitizing music, webmastering, tweeting and tech troubleshooting.

I regularly chronicle life & world travel via Twitter and annotated Google photo albums. Ever in search of the perfect digital photo-management system, I spend more time than any one human should testing, tweaking and breaking several services.

Other personal interests include cappuccino, watching Toronto Blue Jays baseball on PVR delay so we can skip commercials (no spoilers!), our low-carb/high-fat/grain-free/intermittent fasting/ketogenic diet that has helped me lose 175 pounds since 2011, stylus-based gadgets, and natural disaster movies where the rogue atmospheric physicist saves the day.

My home is currently Summerside, PEI, Canada (though I will always be "from Toronto"). My actual physical location could be anywhere in the world as a constant travel companion to my loving husband Joe, with whom the epic "Oshawa vs. Brampton" battle is ongoing.
