Same Share, Different Shape

See that fourths of the same square can be triangles or rectangles.

Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.

What children learn in Level 74

Here are two squares the same size. One is cut up and down. The other is cut corner to corner. Both are cut in half!
The halves of A are rectangles. The halves of B are triangles. Different shapes, but each half is the same size!
Fourths work the same way: 4 little squares, 4 strips, or 4 triangles. They're all fourths of the same square.
What matters is that the shares are equal in size, not that they look alike.
