I set up a shape activity for comparing shapes, more specifically, the size of the shapes. And since its winter, I had to make a snowball activity!
In big math talk, we’re talking (very loosely) about the area of shapes.
With my trusty painter’s tape, I taped out four different shapes on the floor. A square, triangle, diamond and a rectangle. I wasn’t about to take the time to tape out a circle, I’ve done that before, and it takes awhile. But it would be a good one to include too.
Then I grabbed a box of facial tissues and balled up several (probably 30 of them) of them to make into ‘snowballs’ (coffee filters, cotton balls, toilet paper would all work too).
Henry began filling the shapes with the snowballs.
It wasn’t nearly as complicated, or took any problem solving, like the block puzzles we did.
The point of this activity is to compare the size of the shapes.
We talked about the shapes, which one Henry thought was the biggest, and smallest and so on.
Once they were full, well, George and Henry wiped the slate clean and we had snowballs everywhere… so Henry filled the shapes again.
And that may have happened a couple more times too… all in good fun!
Then finally, he counted how many snowballs it took to fill each shape.
Starting with the rectangle, then the diamond… which he found took more snowballs than the rectangle. Then I asked before he started counting the snowballs that filled the triangle.
What do you think, more or less snowballs than the diamond?
So he counted to see. Yep! He was right. And then again with the square, more or less?
Yep! After counting all the snowballs in the square, he found out that the square was the largest shape.
Since our snowballs weren’t a very good measuring tool, this is only loosely comparing the areas of the shapes. But it gives the same idea and Henry a concept of what shape are a larger area and what the idea of area is in general.
And George could have done this activity as well, its just about the counting in their mind. He would have needed help counting that far with some of them though.
