@panlepan The main diagonal is divided into thirds, so the red area is 2/9. https://t.co/sBLUuSII7o

@msbjacobs @el_luna (Didn't need all of 1st diagram; just to click that the diagonal is split into three = parts)

@naomicfisher A few people have mentioned the true case of children being cast away on an island, which @rcbregman tells about in his excellent book Humankind. These children actually looked after each other! https://t.co/mcc559DSJr

This is I's recording of her throwing a dice. She realised she'd done far too many to represent 6...she looked carefully and copied 3 and 3 as she self corrected. Brilliant mathematical mark making in fs this morning @Manor_Wood_Pri

It was about time I got back to writing blog posts: In this, I talk about how we make more of those student ideas and questions that aren't in our anticipated direction for the lesson.

@PardoeMary @ProfSmudge @MLCmath with just two colours

[Simon Gregg @Simon_Gregg]

I like how these triangles are kind of jumbled, but have a kind of order too.

[Simon Gregg @Simon_Gregg]

@PardoeMary @ProfSmudge The great @MLCmath pattern block app runs out of triangles at this point.

[Simon Gregg @Simon_Gregg]

@cellophaneo Yes, since yesterday!

[Simon Gregg @Simon_Gregg]

@MurrayH83 @PardoeMary @ProfSmudge I also like it that - because the 'rings' double in area each time - the central dodecagon has the same area as the first ring.

Canviem colors 🧩

👉🏼 Omple les dues figures iguals amb Pattern Blocks de manera que no comparteixin cap dels colors. Quina estratègia has seguit?

[Simon Gregg @Simon_Gregg]

@MurrayH83 @PardoeMary @ProfSmudge Yeah, I'm fascinated by those 'petals' that come out of the middle!

@Joolone @Tom_Ruen ... it starts to look like this

Experimenting with tilings with half squares #beingmathematical

[Simon Gregg @Simon_Gregg]

@Joolone @Tom_Ruen Playing with these shapes again...

[Andrew Osborne @SumDumThum]

@Tom_Ruen @Simon_Gregg @ZelligeApp It can be interpreted as a truncated hexagonal tiling with the dodecagons dissected, but it can also be interpreted as a weirder tiling involving equilateral triangles, squares, and irregular pentagons.

[Simon Gregg @Simon_Gregg]

Keeping the tiling going a little...

[Simon Gregg @Simon_Gregg]

Oh wow, we can make a dodecagon!
That means we can tile a plane like this too.

[Simon Gregg @Simon_Gregg]

@PardoeMary @ProfSmudge Dodecagons with these. Each 'layer' would be twice the area of the one before.

[Simon Gregg @Simon_Gregg]

@helenjwc These ones are cut from acrylic. Two sizes of equilaterals, and the half-square triangle.
