MrBinfield<p>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.

MrBinfield<p><span class="h-card" translate="no"><a href="https://mathstodon.xyz/@KarenCampe" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>KarenCampe</span></a></span> When I asked the student to tell me more about their thinking, they counted 16 squares, said “4 are yellow, that leaves 12, so 4/12.” Very clearly thinking part:part relationship. Not uncommon at this age. And yes, part:whole and part:part fraction understanding is very important to unpack so we all know what is being spoken of. Not wrong, just looking at a different relationship. <a href="https://mastodon.social/tags/mathschat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mathschat</span></a> <a href="https://mastodon.social/tags/elemmathchat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>elemmathchat</span></a> <a href="https://mastodon.social/tags/msmathchat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>msmathchat</span></a> <a href="https://mastodon.social/tags/iteachmath" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>iteachmath</span></a></p>
MrBinfield<p>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.

MrBinfield<p>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?

MrBinfield<p>This task is from NRich.maths.org. A great task. How would YOU open it up to allow for multiple answers &amp; more math talk? “On a farm there were some hens and sheep.
