### The 2014 program is finished for this year. Please check out our next program the Summer Institute.

The 2014 schedule for Classroom Adventures in Mathematics is now available. The dates are as follows:

**Saturday, April 26th; 10am – 3:00pm * CANCELLED***- We apologize for the inconvenience but, due to a scheduling conflict, this session has been cancelled. Please keep an eye out for our Summer Institute coming soon!

- Saturday, March 22nd; 10am – 3:00pm
**Saturday, February 15th; 10am – 3:00pm**- Fractions are Friends, Not Foes!, Sa’diyya Hendrickson, Instructor, Department of Mathematics
- In the lesson we will explore a strategic way of handling operations on fractions/rational numbers and more generally, rational expressions (i.e. fractions involving variables). The goal is to help students develop a fluency with these numbers, and consequently reduce the all too common “phobia of fractions.” We will then use this approach to facilitate a very natural transition from rational numbers to rational expressions, which are just fractions in disguise.
- Sa’diyya is currently an instructor of PUMP, which is a precalculus course offered by the Department of Mathematics to prepare students for university-level math. She is also an Ontario Certified Teacher at the Intermediate/Senior level, with teachables: Mathematics and Family Studies. Her present work in the field includes teaching at U of T, giving private math lessons to students ranging from primary grades through university-level, and volunteering to support students at a local high school’s Math Homework Club. Her main goal as an educator is to find new and creative ways to teach mathematics so that it’s more accessible and enjoyable to all students.

- Fun with Algebra, Dr. Alia Sajjad, PhD in Statistics
- We will see how arithmetic and algebra combine together to create interesting mathematical tricks, which some mathematicians call “Mathemagic” and others refers as “Mathematical magic”. It’s fascinating to observe and perform this magic, but more captivating to step into the amazing world of mathematics behind it.
- Dr. Alia Sajjad is a PhD in Statistics. Her field of research is “Design and Analysis of Experiments”. She has recently moved to Canada. She has been teaching at the Statistics Department of Quaid-i-Azam University Islamabad, Pakistan as a visiting faculty member before moving to Canada. She has an experience of teaching Mathematics to undergraduate students at different government colleges for fifteen years. She has been a fellow of Issac Newton Institute for Mathematical Sciences in 2011 for Design and Analysis of Experiments (DAE) Program.

- Mathematical Mistakes, Zhaoyun (Helen) Wang, PhD student, OISE
- This lesson is to identify misconceptions in secondary school mathematics learning. These misconceptions are related to the concepts of elementary school mathematics and undergraduate mathematics learning. The identification and modification will help teachers to address these problems in teaching and also help teachers’ professional development. The knowledge will positively influence students’ performance.
- Zhaoyun (Helen) Wang is a PhD candidate at Ontario Institute for Studies in Education (OISE), University of Toronto. Before studying at OISE, she was a mathematics teacher and a coach of mathematics competition at Oklahoma School of Science and Mathematics, Oklahoma, USA. Before working in Oklahoma, she taught preservice and inservice mathematics and computer teachers in Tianjin China. She has taught mathematics, computer science, and educational theory courses for more than 20 years. She attained master degree in mathematics education from University of Calgary.

- Fractions are Friends, Not Foes!, Sa’diyya Hendrickson, Instructor, Department of Mathematics
**Saturday, January 18th; 10am – 3:00pm (Videos Now Available)**- Visualizing the Fourth Dimension, and the Simplest Thing I Don’t Know About It, Dror Bar-Natan, Professor, Department of Mathematics
- Much as we can understand 3-dimensional objects by staring at their pictures and x-ray images and slices in 2-dimensions, so can we understand 4-dimensional objects by staring at their pictures and x-ray images and slices in 3-dimensions, capitalizing on the fact that we understand 3-dimensions pretty well. So we will spend some time staring at and understanding various 2-dimensional views of a 3-dimensional elephant, and then even more simply, various 2-dimensional views of some 3-dimensional knots. This achieved, we’ll take the leap and visualize some 4-dimensional knots by their various traces in 3-dimensional space, and this achieved, I will tell you about the simplest problem in 4-dimensional knot theory whose solution I don’t know.

- Absolute Chaos is Impossible!, Mike Pawliuk, Graduate Student, Department of Mathematics
- Given a large enough set of data you will always be able to find some sort of structure in it – it is impossible to avoid every type of pattern. We will make sense of this in a concrete mathematical way by introducing what is called Ramsey Theory. We will also see how these give rise to mathematical games that can be played in the classroom. (click here for handout)
- Micheal Pawliuk is a 4th year PhD student in mathematics. He alternates between studying infinities (yes, plural!) and contest math for high school students. You can read more about him on his website: http://boolesrings.org/mpawliuk/

- Workshops, Patrick Finnigan, IEEE (The 100+ lesson plans for these and other topics are at http://tryengineering.org/ and http://trycomputing.org/)
- Binary Searching and Sorting: This lesson reinforces students’ ability to write, read, and compare small binary numbers. It also shows how the simple properties of binary can be used to do useful tasks quickly. The lesson introduces beginning students to the simple properties of binary logic – “compare”, AND, OR, NOT. We do some simple sorting and also do an exercise coding binary information for retrieval.
- Introduction to Algorithms and Complexity: This lesson delves further into algorithms and their complexity. Classroom exercises involve: solving problems using decision trees, creating graphs to solve problems, characterizing sequences in terms of complexity.
- Pat Finnigan is a Professional Engineer (Electrical) and a Senior Member of the Institute of Electrical and Electronic Engineers. He spent 30 years programming at IBM and for many years he has collected “anything that calculates”. He has an M.Math from Waterloo, and has been involved for the last 5 years with IEEE’s “TISP” program delivering workshops and lesson plans for hands-on science, math and engineering to high school teachers and IEEE volunteers.

- Visualizing the Fourth Dimension, and the Simplest Thing I Don’t Know About It, Dror Bar-Natan, Professor, Department of Mathematics

To register please fill out the following form, there is no cost to participate in this program.

All sessions take place at the Bahen Center for Information Technology located at 40 St George St, Toronto, ON M5S2E4

The topics for each session will be released on this page closer to the date. This year, in order to accommodate more diverse interests each session will cover a range of mathematics topics instead of one single theme.
