Welcome to the
TAMU Math Circle!
Welcome back to TAMU Math Circle! We look forward to seeing you again on 1/30!
Spring 2021 Meetings: 1/30, 2/6, 2/13, 2/20, 3/6, 3/13, 3/27, 4/17, 4/24, 5/8, 5/15. If you already attended the Math Circle in the fall, there is no need to register/pay. The daily schedule will remain the same. We will provide updated Zoom information shortly.
The Texas A&M Math Circle is an outreach activity that brings 5th - 12th grade students into direct contact with mathematical professionals in an informal setting to work on interesting topics in mathematics. The goal is to help students become passionate about math. Our instructors range from professors and graduate students at Texas A&M to experts from industry, all of whom are eager to share with students their passion for mathematics and its applications.
Meetings will be held online via Zoom. For the Spring 2021 semester, we will have meetings on 1/30, 2/6, 2/13, 2/20, 3/6, 3/13, 3/27, 4/17, 4/24, 5/8, 5/15. These are all Saturdays.
Discovery Learning Sessions:
12.00 - 1.30 (Beginner)
1.45 - 3.15 (Intermediate)
3.30 - 5.00 (Advanced)
Problem Solving Sessions:
12.00 - 1.30 (Advanced)
1.45 - 3.15 (Beginner)
3.30 - 5.00 (Intermediate)
We will have two simultaneous Zoom Meetings open from 12.00 to 5.00 PM on Saturdays; one meeting for Discovery Learning, and another meeting for Problem Solving. Students who wish to attend both discovery learning and problem solving activities will need to move from one meeting to the other during the 15 minute transition period.
Previous Meeting (December 12, 2020):
December 12, 2020
Discovery Learning: Beginner Group (12.00 - 1.30 PM)
Speaker: Dr. Maya Johnson (TAMU)
Title: Lady Bugs
Abstract: How many lady bugs can you save? This activity involves helping lady buys safely land on leaves. There are two leaves and lady bugs with an integer number of dots on their backs. You must place the lady bugs on each leaf in consecutive order starting from number one. If you place a lady bug on a leaf where the sum of the dots on the backs of any two existing lady bugs equals the number of dots on that lady bug’s back, then all the lady bugs will fly off the leaf. If you reach a point where any move you make would cause the lady bugs on both leaves to fly off, then the game is over and you have to start again. The question is: how many lady bugs can you get onto the leaves without them all flying away? We will explore what’s the best strategy for placing the lady bugs to get the most lady bugs to safety as possible with consecutive numbers first and then see what happens if we switch to even numbers, odd numbers, primes, and other different cases. Come join us for some buggy fun with numbers!
Discovery Learning: Intermediate Group (1.45 - 3.15 PM)
Speaker: Matthew Atanas (TAMU)
Title: "What's for Dinner?" - An Examination of Different Voting Systems
Abstract: In this activity we will explore several different voting systems and evaluate the benefits and detriments of each. We will conclude with a surprising result on the possibility of "fair" voting systems.
Discovery Learning: Advanced Group (3.30 - 5.00 PM)
Speaker: Alexander Riedel (TAMU)
Title: Power of a Point and Radical Axis: Proving a theorem relating the chords in circles with high school geometry
Abstract: We will first examine the intersection of chords in circles and prove a theorem using high school geometry techniques. Then we will define the Power of a point and the Radical Axis of two circles. We will proceed to find what the radical axis is for two circles and prove some useful facts about it.
Problem-Solving: Beginner Group (1.45 - 3.15 PM)
Instructor: Drs. Irina Bobkova and Guangbo Xu (Texas A&M University)
Problem-Solving: Intermediate Group (3.30 - 5.00 PM)
Instructor: Xiaoyu Su & Drs. Li Gao, Hao Guo (Texas A&M University)
Problem-Solving: Advanced Group (12.00 - 1.30 PM)
Instructors: Drs. Zhizhang Xie, Rodrigo Matos, Andrew Yu (Texas A&M University)
