Building Number Sense With Subitizing, Lindsey Herlehy

Publications & Research

Dice, fingers, tallies, and ten frames! Proficient mathematicians are problem solvers who work with quantities in flexible ways. Subitizing is a practice that builds number sense and is key to becoming a fluent mathematician at any grade level. Quick and easy games and activities will be shared.

Content Validity Of A Mathematics Placement Test For A Gifted High School, Hannah R. Anderson

Publications & Research

The Content Validity of a mathematics placement test at a Science, Technology, Engineering, and Mathematics (STEM) gifted residential high school is examined. Data were collected from internal and external mathematics subject matter experts (SMEs) using a card- sorting task and were analyzed using Multidimensional Scaling (MDS) and Hierarchical Cluster Analysis (HCA). Results demonstrate some congruence between the two configurations, suggesting marginal evidence of Content Validity.

Stem Integration: Math, Meet Biology!, Lindsey Herlehy, Karen Togliatti

Publications & Research

Join us for three hands-on, inquiry-based activities integrating mathematical and scientific thinking. First, explore patterns in the powers of ten and use this information to sort a set of images and design a scale model of an E. coli's DNA. Then, simulate a colorful biotechnology application using new tools and laboratory skills. Art, science, and math intersect in an activity merging coordinate geometry, symmetry, and biotechnology skills. NGSS and CCSS practice standards will be demonstrated.

2017: "From Sea To Shining Sea: Looking Ahead With The National Park Service", Abhay Gupta '18, James Wei '18, Istvan Kovach '18, Shyam Sai '18, Darius Hong '18

Distinguished Student Work

There is a natural inclination for humanity to view the Earth as our steadfast, never-changing home. After all, it seems as permanent as the ground beneath our feet. However, nothing could be further from the truth, especially in today’s rapidly changing climes. Global temperatures are on the rise, and with them comes an increase in sea levels, wildfires, and hurricanes, three serious, expensive issues. Unfortunately for the National Park Service (NPS), who guard ninety-seven coastal units, coastlines are especially vulnerable to such problems. Thus, the NPS must take extra precautions and expenditures to maintain and protect them. With limited budget, …

2017: "Park2vec: A Vector Representation Of Our National Parks’ Climate Change Susceptibility", William Tong '17, Ankit Agarwal '17, George Moe '17, Aakash Lakshmanan '17

Distinguished Student Work

With over 400 units, between them covering almost 850 million acres of carefully preserved land, the National Park Service (NPS) acts as steward to the nation’s natural treasures. In the move to the Twenty-First century, the NPS faces numerous looming challenges, particularly those related to a rapidly changing climate. It was our task to strategize with the Service in addressing three such issues, leveraging our experience in mathematical modelling and data analysis to aid them in the quest to protect and to preserve.

The first problem under consideration was determining the risk associated with sea-level change for five different coastal …

2016: "Analysis Of The Effectiveness Of Varying Car-Sharing Business Models", William Tong '17, Sachin Govind '16, Ankit Agarwal '17, David Xu '16, George Moe '17

Distinguished Student Work

A continually evolving field, the automotive industry consistently introduces a number of innovative technologies and services to ease the problem of transportation. One such service is termed Car-sharing. Car-sharing allows users to rent vehicles and use them for a short period of time without worrying about the additional costs associated with maintenance, fuel, and pollution, presenting a simple alternative to owning a car. Still an emerging concept, Car-sharing requires a great deal more analysis to fully understand the nuances and implications behind its implementation.

Bc 1 Rate Of Change Activity Sheet Teacher Notes, Ruth Dover

A Simple Introduction to Rates

Before beginning this section of handouts, students will be introduced to a variety of vocabulary words often associated with calculus. These words will be used in an intuitive sense only and will not have been formally defined. Vocabulary should include graphical terms such as continuous, increasing, decreasing, maximum and minimum points, concave up, concave down, and point of inflection. In addition, discussion of the concept of "rate of change" should begin. It should be mentioned that many quantities change – population, cost, and temperature, to name just a few. All that is specifically required at this point can be related …
