Nrich Problems

I have made reference to the problems on Nrich’s website so many times, I feel like I should start adding a “u” to the phrase ‘favourite website.’   it seems like whenever I look at how to engage students, differentiate lessons, encourage deep mathematical thinking, help students communicate mathematically, and so on, I always lean on Nrich to provide me with the right problem to fit the bill.

Here is a collection of my favorites that I use in Algebra class:

Always a Multiple – students explore number tricks and try to work out how they work.

Calendar Capers – using a calendar, students investigate what happens when different operations are performed on sections of the dates.

Pair Products – a personal favorite where students apply their skills in expanding algebraic expressions toward generalizing results.
