Just made this with geogebra. I think next year I will use this as an activity to get pre-calculus reacquainted with geogebra. 

Prompt: Search online for an impossible shape. Recreate it using geogebra.

A new post about a conversation I had with an insightful student who helps out in a 6th grade math class.

A great post about why teachers are invaluable in the world of education. If our job is simply content delivery, we can be outsourced. If our job is to know our students and help them find and connect their interests to learning, then we are irreplaceable.

"Disrupt the nervous, tentative student from erasing all of her answers and replacing them with what her classmates present. If there is a large chance that the answers being presented aren’t quite right, you can’t immediately assume that yours are wrong."

I have often seen kids doing this during presentations of problems by their classmates. I hate it and I hate what it represents on an emotional and cognitive level. The feeling that you can't get anything right is crippling in math class. The frustration of erasing your answers only to find out they were right is maddening. What is much more powerful is to be able to have a different answer and to think through your work and the presenter's work carefully deciding where the difference is.

A great article with a phenomenal first sentence: 

"Like everyone else I know, when winter comes I think of Plato’s theory of ideal forms."
