Projects for Geometry: It's Not Just Rules and Proofs
The first mathematics that the ancients began to explore was Geometry in an attempt to describe the world around them. The visual universe awed them, and they developed Geometry to explain what they were seeing. Today, we often lose sight of the beauty of Geometry as we focus on the rules, proofs, and problem-solving techniques to help students pass tests. These projects, which take little classroom time, can enhance what your students are studying and why they are learning it. Having your students observe Geometry all around them provides meaning, purpose and excitement to their studies and gives them a reason for expending all of their efforts.

Can College-Level Remedial Math Programs Work?
A report on a study to test the efficacy of college-level remedial math programs, specifically in community colleges. In this study, chi-square independence test and logistic regression were used to compare the long-term academic outcomes of first-year community college students. Findings show that students requiring remediation in mathematics and successfully remediated into a college-level math class, experienced comparable outcomes to those not requiring math remediation, indicating that remedial math programs can be highly effective at resolving skill deficiencies.

Making Algebra 2 and Precalculus "Fun" through Meaningful Projects and Classroom Activities
During this session I will share a variety of alternative assessments and activities to help inspire the algebra 2 student and the pre-calculus student. Some activities include FACEing Math (creating a famous face through solving math problems), Math Concepts Go to the Movies (students use a movie to inspire classmates), MATHO (a competitive activity that can be differentiated for all levels of math students) and Picture This! GeoGebra Functions (the use of functions, specifically domain, range and transformations, to create an original, yet recognizable, design.) All activities are ready for you to use tomorrow. Some new activites will be added this year to include Algebra 2.
How NOT to Teach Statistics
Statistics courses routinely teach students about the Normal Distribution (otherwise known as the Normal Probability Density function) without or before teaching about probability, random variables and probability density functions. Statistics courses present the idea of a z-score – a “standardized value”, where z = (x minus mu)/sigma – without connecting this formula to the process of transforming other algebraic functions that students may know. Formulas are presented without justification or proof and we teach students how to used “official tables” of the sum of probabilities without any explanation of how the table data generated (integrals of the probability density function). In fact, since statistical analysis is done using computer-based packages like R and SAS, many students are not even given practice in using the formulas.
This talk will suggest some historical and structural reasons for the problem, some ways to make statistics more meaningful to students, and curricular changes that are needed to prepare all students to understand and use statistics.

Empowering Students Who Ask, "When Are We Ever Going to Use this Math?"
When Math is presented as a life skill that broadens career choice and inspires critical thinking, students embrace the learning of reasoning and problem-solving skills while building confidence and persistence. While many students will not major in science or engineering in college, all students benefit from the challenge and discipline of Math. This positive attitude can help teachers, administrators and students to meet the challenges of ‘teaching to the test’ by viewing it as an opportunity to address common errors and misunderstandings without formally reviewing. In fact, the comparison of multiple choice answers can help students to “think on their feet” while increasing accuracy, logic and frustration tolerance skills – assets in high school, college and the workplace. Worksheets will cover common secondary content incorporating Common Core and SAT content (including algebra, geometry, trig and precalc) and will use multiple representations and technology to appeal to diverse learning styles creating a path to success for all.

The Math of Student Loans
Many students need to take out student loans in order to attend college. Because these loans are a financial commitment that spans decades for the borrower, it is beneficial to have a mathematical understanding as to how the repayment process works. The math behind student loans is accessible and applicable to students with an algebra background; it involves exponents, percents, and compound interest. We will look at how the monthly payment of a student loan is determined, how to calculate the amount of interest that will be paid over the life of the loan, and the long-term effect of paying a small amount above the monthly payment each month.

Coins, Cards, Counting, and the Common Core
What must students know in their future in probability and statistics for the new Common Core standards? And the more important question, how are we going to fit this in? Both will be discussed along with methods of demonstrating these probabilistic and statistical concepts for all grade levels.
Michael Weingart – Rutgers University:
The Prosecutor's Fallacy
The prosecutor asserts that based on evidence from the scene of the crime, the perpetrator had characteristics A, B, C, D, ... The defendant has all these characteristics. Since the probability that a randomly selected person has all these characteristics is only 0.00001, it is overwhelmingly likely, says the prosecutor, beyond reasonable doubt, that the defendant is guilty. Hmmm. There is a subtle fallacy pertaining to conditional probability lurking within the prosecutor's argument, and we will sort out what it is in this talk.
