Students and Teachers alike, though mostly for teacher resources.
Use it for enrichment, when those extra problems are needed.
Good question. The organization is subject to change as I flesh this out more.
My original idea is by grade level, but some of these can be used at all grade levels.
By topic? Too broad, I think.
We will see...
April 21 2026 - Modified Calc and Vectors to have a Challenge/Thinking Problem Section
Added a document for the Limits Unit for Challenge Problems (since currently teaching that unit)
April 2026 - Came across STEP (Sixth Term Evaluation Papers) questions which are used in the UK for admissions into math programs.
Working through 2018 and modify/adapting questions to be suitable for current Ontario/IB math programs.
Most of these are for grade 12 Ontario Math courses, so look for them there.
February 2026 - Added Dinnertime Math section, Math Man (didn't want to lose these)
January 2026 - Added my current IB Paper 3's to the Post Secondary Explorations
December 2025 - Finally began this webpage with my retirement in mind. Thanks to GVMA for allowing me to do this.

These are links to puzzle websites that are great for students. I've used variations of these for the Halton Math Contest, warm ups in class, cool downs in class, etc... Some of the more obscure are great since it forces students to create their own rules. Provided by the Krazydad website.
These are links to problem solving sites that I have used extensively over my years of teaching. They are excellent and the source of some of the material here. I highly recommend them!
