Learning about angles using a dynamic fan model. Use the fan to compare the angles formed by dancers’ arms and to orient yourself on land. https://t.co/9W2NIDOmyW

Another activity to develop spatial, holistic reasoning in mathematics. Thinking of the changing phases of the moon and how they relate to circles. Two Circles: https://t.co/FGj21zXpYX🙏 @dpscher and Quincy Wang. #bcedchat #bcamt #geometry

Exploring and constructing polgons while meeting new geometric vocabulary and making shapes you have never seen before! A Plethora of Polygons: https://t.co/rtDEcM3RRC. #bcamt #bcedchat

We are working on new activities for elem school kids... interesting, engaging & deep mathematics... The first one is up: https://t.co/9W2NIDOmyW. Thanks Sandy Bakos, @annetterouleau, Victoria Guyevskey, Rebecca Cohen. Check out Symmetry & Triangles activities. #bcedchat #bcamt.

#STEAMdays T=Tech Tuesday ... explore block symmetry with Web Sketch Pad tasks from @geometry4yl #thanks https://t.co/xe1lwSSd7Z using https://t.co/NNxran0N0g

[Geometry4YL @geometry4yl]

Exploring tessellations with websketchpad: some are familiar and some are chellenging our definition about no overlap and no gap.

Or, in the colour calculator, 28513/99999 with table width 6 for the left and table width 5 for the right. Try! https://t.co/clLTaP27t1

Desirée Patterson uses geometric transformations of photographs—anamorphic like—to explore human impact on nature. See her Anthropocene art at the King Edward station!

Enjoying shooting lightning bolts from my fingertips to represent multiplication arrays using the new TouchTimes app on my iPad. https://t.co/wjc0pLjSaA #mtbos #iteachmath

Making symmetry with some two handed rope work at the Fröbel museum in Bad Blankenburg

For when you need to make a straight line on the board: unroll the string from the device, which coats it with chalk, pin to board and give the string a quick tug. Ta da! Who needs rulers anyway?

[Geometry4YL @geometry4yl]

For when you need a break from Platonic solids... diversity of faces so attractive...

2000 BCE Assyrian circles and triangles. Our constant companions for more than four thousand years. .

[Geometry4YL @geometry4yl]

A compass for those who >really< like circles.

@cafedepruner @JohannaIM But there could be ways of doing both, especially conics, that fit nicely with the big ideas and the competencies. What do you think, Mike?

Moiré dynamic geometry by Takahiro Kurashima. This “poemotion” turns circles into@polygons.

Froebel’s first gift: balls of yarn. Sensory experiences of lines, loops, crossings, insides, boundaries... all lures into geometry
