TVM Solver and Loan Payment Calculator - Google Sheets Version
This Google Sheets-based TVM Solver mimics the behavior of the familiar TI-84 calculator application. You can use all the same instructions you always do. Students simply leave the field they wish to solve for blank. I know how difficult it can be to get a good TVM solver into the hands of your students when they are working from home on a variety of devices. I also included a Loan Payment Calculator to determine the monthly, weekly, or biweekly payment, given the principal amount, annual inte

Teaching style
Whenever possible, math should be driven by engaging problems that pull students into the concepts and skills I seek to teach. 'Fruitfully frustrated' is a good place to be :)
I enjoy writing and performing math raps (youtube CalfordMath), integrating Geometer's Sketchpad to bring dynamic understanding, gamifying learning (see my product 'Algebra Tile Factris'), and generally pushing creative limits to make math concepts accessible to my students.
I am aware of students' math stigmas and horror stories. I try to build on their natural math intuitions, sidestepping their perceived inability to 'do math' because they never won a class game of around-the-world with multiplication flash cards in grade 4.

Additional biographical information
I'm an avid recreational chess player. I enjoy music, skateboarding, longboarding, rapping, programming (see my product 'Algebra Tile Factirs' for a computer game example, or my 'Colouring by...' products for an automated worksheet product), and doing math for fun (total geek).
