Leaf Sort

1 Comment


Our interest in leaves last week inspired a throw-back morning message today.  Four leaves were featured and we encouraged the children to support their choices with evidence.  Some noticed that a leaf was a different shape or had a different proliferation of spots.  Others pointed out the color differences.  We were interested in finding many ways to group even a small selection of items.

Once we had experience with finding a single difference, we expanded the activity to combining like items to make sets.

The children invented the “rules” for these set circles.

The "not spikey" leaves.

The problem occurred when our final leaf was placed in the “not spiky” set.  A few children disagreed about the general “spikiness” of the long, fern-like leaf.  It looked “spiky” in its overall profile, but each individual leaf was actually rounded.

The children decided that it must go in both circles.

This one is both spikey and not spikey.

This one is both spiky and not spiky.

As you can see, another difficulty arose.  If the leaf was in-between the circles, it was in neither group.  If it was creating a bridge between the circles, it was partly in both circles.

What if we place it so it hangs in  both circles.

It took a bit of playing with the string, but they did discover that if they overlapped the string, it would make a section for a leaf with both attributes.

Will it fit in this intersection?

Now we have a diagram that explains how our leaves fit together.

One thought on “Leaf Sort

  1. Marie, I love your blog! It will take me some time, but I’ll be reading all your prior posts. I’m glad you found my blog, too. Like you, I write about all that’s important, whether it’s something that happened in the classroom, or a message that comes from years of observing. I started in March, yet I haven’t tried anything ‘fancy’, like adding photos. I’ll get there. So glad we ‘met’, and yes, we teach the same thing in the same way. -Jennie-
