Which one speaks to you more? What math do you see? What conversations would you start? #fractiontalk #howmany #ElemMathChat #msmathchat #iteachmath #mathchat
@MrBinfield I mean right circle is all pyramids (polygon base, ~ cross-sections, lateral faces are triangles)
Left circle is all prisms (parallel congruent bases, congruent cross-sections, lateral faces rectangles) but I think the student is noticing the square/rectangular base feature of those.
The overlap is a pyramid with a square base, so has both attributes: pointy top and square bottom.
BUT I didn't see the triangular prism in the left circle when I wrote my 1st comment.
That could be a mis-categorization if the student sees the base as "the bottom" and that prism is "lying down".

How often do we talk about 3D figures based on geometric properties? What would you call these two figures? What other names do they go by? Van Hiele helps us think about the goal of geometric thinking. Where does your grade land? #mathchat #elemmathchat #iteachmath #msmathchat

Always, Sometimes, Never? A rectangle is a aquare?

Always, Sometimes Never? A kite is a square?

Always, Sometimes, Never? A shape has 2 or more pairs of parallel sides?

What A/S/N statement can you create to create optimal levels confusion?

Gr 3 S drew this for fun. I asked “What fraction is yellow?” S responded “ 4/12. What are they noticing? What question would you ask next? Keep in mind not part of a lesson. Just for funsises. #iteachmath #elemmathchat #mathchat
How do you see this pattern growing? What will the next term “look like?” What stays the same? What changes? Can you predict a far term? How about the nth term? #elemmathchat #mathchat #iteachmath
In your #thinkingclassroom who is doing the thinking? How have you intentionally set up constraints to foster a zone of optimal confusion in students? #iteachmath #elemmathchat #mathchat #msmathchat
