A neat puzzle-
1. Shade any 2 sections
2. What fraction of the square is shaded?
3. What other fractions are possible? Impossible?
This puzzle kicked off discussions at a workshop for PD Hub members.

When subtracting from a number that ends with a lot of zeros, consider subtracting 1 from both numbers so we don't have to "borrow" several times.
ALT Top: Spongebob looking stressed. 10,000-4,289 with the "borrowing" method. Bottom: Spongebob looking cool, snapping fingers. 10,000-4,289 turns to 9,999-4,288=5,711

Here are some problems I have curated and used with my middle schoolers for at least 20 years…long before we began calling them “non-curricular tasks”.
I just wanted to share with the #mtbos community that has given me so much.

If you highlight all multiples of numbers in this triangle with a variety of names (Halayudah, Khayyam, Yang Hui, Pascal, Staircase of Mount Meru), beautiful patterns emerge. What do you notice or wonder? Explore for yourself at math.fit/pascal-fractals
