Yesterday I copied a math problem from a textbook onto a test. Today as I was grading the test, I discovered that the geometry of the triangles (as drawn in the textbook) was impossible. As a result students’ answers varied depending on their process.
Should you ever decide to write a textbook, please make sure your geometry works out.
On a lighter note, having had chili dogs on their sign since I arrived in Ubon, the Dairy Queen in Big C now actually sells chili dogs!
