Student Classes

Parents are allowed to drop off students at 9:30 am. Classes are from 10:00 am to 3:00 pm. There will be a supervised lunch period from 12:00 pm to 1:00 pm in which students must bring lunch and drink. Students are NOT allowed to leave campus to purchase lunch. We will also have an optional after-school mathematical activities session from 3:00 pm to 5:00 pm.

Remote classes will be from 10-12pm, and 1-3pm. There will be an unsupervised lunch hour from 12pm-1pm.

Bring a notebook and pencil or pen to class. MS classes usually assign about half an hour of homework weekly, whereas HS classes assign about one hour. Year 1 for the HS curriculum starts in the fall of even years (e.g., fall 2022), and year two starts in the fall of odd years.

MSA is a one-year program appropriate for Elementary or Middle School students who are new to problem-solving. They should have strong arithmetic skills and an interest in learning mathematics beyond the school curriculum. Topics and sample questions.

MSB is a one-year intermediate program appropriate for students who have completed the equivalent of MSA. Topics and sample questions.

HSA is a two-year program appropriate for younger high school students and advanced middle school students who may be new to problem-solving. They should be comfortable with regular high school material, including at least Algebra 1. Topics and sample questions.

To be announced

Students attending the Clinton School classes should wear a mask unless the instructor indicates otherwise.

Presenting Polygons. In this three-day workshop, students will explore polygons. They will be able to identify them by the number of sides. They will distinguish between regular and irregular polygons. They will be able to find the sum of the measures of the angles of a polygon. They will be able to find the measure of each angle of any regular polygon. They will develop the formula for finding the area of a regular polygon. Students will need a scientific calculator and should have working knowledge of computers as there are several websites we will access.

Recursive Sequences: Two-day workshop. A sequence is a list of things (usually numbers) that are in order. Many sequences have patterns that a recursive formula can describe. In Algebra class, we learned that general methods exist to find the explicit formula for arithmetic and geometric sequences, but what about other recursive sequences? In this workshop, we will explore methods of writing explicit formulas for some sequences that are neither arithmetic nor geometric. We will also examine Fibonacci-style sequences in the form x_(n+1)=a*x_(n)+b*x_(n-1) and find the explicit formula of the Fibonacci Sequence with elementary algebraic methods. At the end of the workshop, we'll look at how the Golden Ratio is related to the Fibonacci Sequence. This workshop is recommended for students familiar with arithmetic and geometric sequences and solving systems of linear equations.

MS Intro to Geometry: This three-day workshop is targeted at Middle School students who a have basic understanding of geometric shapes (triangle, quadrilateral, rectangle, square, parallelogram, rhombus, kite, trapezoid/isosceles trapezoid, circle) and angles (right angle, straight angle, parallel lines, acute angle, obtuse angle, degree measure). We will discuss problems involving circle geometry, the Pythagorean Theorem, and its applications, including coordinate geometry and finding areas of shaded regions (e.g., bounded by two sides of a right triangle and a circle inscribed into it.) The problems will be on the National MathCounts level.

HS Contest Topics in Geometry: This three-day workshop targets students with a solid foundation in basic geometry. For example, a score of 95+ on Geometry Regents would qualify a student for this class. This 3-class workshop will cover some common ideas in Plane Geometry, problems involving areas, and 3D geometry. The level of the problems will be AMC 10 #15-#25.

Bring a notebook and pencil or pen to class. MS classes usually assign about half an hour of homework per week, whereas HS classes assign about one hour. Year 1 for the HS curriculum starts in the fall of even years (e.g., fall 2022), and year 2 starts in the fall of odd years.

MSA is a one-year program appropriate for Elementary or Middle School students who are new to problem-solving. They should have strong arithmetic skills and an interest in learning mathematics beyond the school curriculum. Topics and sample questions.

MSB is a one-year intermediate program appropriate for students who have completed the equivalent of MSA. Topics and sample questions.

MSC is an advanced one-year program appropriate for students who have completed the equivalent of MSB and have had exposure to Algebra 1. Topics and sample questions.

The Sum-Product Problem

DESCRIPTION: The sum-product problem is a major open problem in mathematics. Several of the world's leading mathematicians have been struggling with this problem over the past decades, making slow progress. At the same time, hardly any mathematical background is required for understanding this problem, since it only deals with sums and products of numbers. We will discuss the sum-product problem and see one of the major breakthroughs that was made for it. We will also have a brief chat about math research projects for high-school students.

Adam Sheffer is a professor of mathematics at the CUNY Graduate Center and the Director of Computer Science at CUNY's Baruch College. He is also the director of two programs where promising college students from across the country pursue math research, sponsored by the National Science Foundation. This year, his book "Polynomial Methods and Incidence Theory" was published by Cambridge University Press.

This is targeted to HS students. Due to limited space available, parents and guests are not invited. Light snacks will be served from 12:00pm to 12:30pm.

Elementary School Workshops consist of three one hour sessions, and classes are capped at 12 students. Class A (1-2 pm) is for students below fourth grade. Class B (2-3 pm) is for fourth- and fifth-grade students and will go faster than Class A. Students will work in groups to solve problems. We will discuss efficient methods of problem-solving.

ES PROBLEM-SOLVING 1: Logic and patterns.

ES PROBLEM-SOLVING 2: Guess and check; draw a picture.

ES PROBLEM-SOLVING 3: Make a chart/table; simplify.

--------------------------------------------------------------------------

Middle School Workshops consist of three two hour sessions.

MS CONTEST 1 TOPICS: Algebra - Digits Problems, Base-n numbers, Discussion of cases.

MS CONTEST 2 TOPICS: Geometry - Triangles & Quadrilaterals, Circles & Volume, Funky Figures.

MS CONTEST 3 TOPICS: Probability - Probability, Geometric Probability, Combinations, and Permutations.

Mathematics of Origami: During this two-session workshop, we will explore modular origami - ways of combining origami units to make more complicated shapes. This workshop is hands-on - we will make some of the models in this video.

The Summer MSHS Math Circle is a weekday program for students entering grades 6-12 in the fall that runs for two weeks, four hours a day. A typical day consists of a class in the morning, followed by an offline, unsupervised one-hour lunch, and a class on a different topic in the afternoon. Instructors are very friendly and helpful. We do expect students to use their registration names and turn on their live videos during online class sessions. Virtual backgrounds are allowed.

MSA/MSA+: Geometry and Algebra to describe patterns

MSB/MSB+: Algebra and Graphing, and Math contest topics

MSC/MSC+: Continued Fractions, from Pythagorean triples to Fermat's last theorem for n=3 and n=4

HS Problem Solving: Math contest topics, and Algebra
