So, what IS “mathematics”?
A. Something that you “know”B. Something that you “do”C. All of the above!
Mathematics is a VERB – something you “do”

Standards for Mathematical Practice
1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of structure.

Student Responses
Students rarely, if ever, answer a question “wrong.” Instead, they give a “correct” answer to a different question than we thought we were asking!

An Old Joke
•How do you kill a blue elephant?•With a blue elephant gun.•How do you kill a white elephant?•With a white elephant gun?•No, you first strangle the
elephant until it turns blue and then use the blue elephant gun you already have!

Chinese Proverb
Give me a fish and I eat for a day.Teach me to fish and I eat for a lifetime.
