Mathematical modelling (and how to prepare for exams!)
[PSLE Maths and up: Mathematics Modelling for Teachers] Kept you waiting, huh? You'll find this post to have a somewhat unusual approach compared to the sort of high-quality content you'd have expected from this blog. The following video might be a bit boring, but let me try to explain it: What's important to understand, is that this happens pretty much every day in the staff room. Basically, this is the preferred means of modelling that school teachers tend to use when desig
Cats in Boxes (Not Schrödinger) solution
[P4 Maths and Up: Logic Puzzle] Let's cover the solution right away, shall we? Cops and robbers running around Graphtopia, cats and you running around boxes, there's not much of a difference from the mathematical standpoint. It's with this example that, as you can see, it's never quite so easy to catch a cat unless it wants to be caught, or it's unfortunately stuck in a formation where it has no choice but to enter a pitfall.
Cats in Boxes (Not Schrödinger)
[P4 Maths and Up: Logic Puzzle] Kept you waiting, huh? Here's an interesting puzzle you may, or may not, have seen before. The hiding cat puzzle ends with a fairly simple answer, to do a sweeping search of the boxes (leave the last two boxes unchecked, and check all other boxes row by row) Of course, this puzzle only really works because of a few limitations: 1) The cat only moves at night. 2) The cat is forced to obey the rules and move to a different box ever night.
