In 1982 a graduate student DM supervised my student teaching at a middle school in Central New York. I had some time to plan lessons, and I was scared out of my wits. DM was gentle and direct. She gave me little things I could work on to improve my practice. I did not learn how to teach during student teaching, but I did learn that nothing is perfect and you have to put yourself into a different space to help students learn. I learned how difficult teaching was. It was not until a few years later; I read “Freedom to Learn” by Carl Rogers. This book allowed me to understand the power I had to assist in student learning, but why didn’t I get that then. Why didn’t I get that teaching was about facilitating learning. Jack Mallan’s “No Giver’s of Direction–No Gods In the Classroom” did not make sense to me when it was required, but Carl did, once I started to teach. The power to teach is in the trust you have in yourself and the trust you build in your students to learn. Teaching math is a subject that screams trust your students because we all are born mathematicians. We all can engage with one another as we build our capacity to learn math. It is a subject that requires interaction, iteration, experimentation, communication, and creativity. These processes are we learn and do mathematics.
In hindsight, it was Dr. HJ who convinced me that Mathematics Education was the path for me, and I learned about teaching EOP students as part of a summer program back in 1983. I was trusted by Dr. HJ to teach mathematics to new students at a good university. Somehow I was trusted as a new teacher to figure out what to do. Why Dr. HJ. trusted me, I have no idea. I taught exactly how I was taught. Students learned, but I also learned things that are never in a textbook. I learned how to ensure that students’ learning, but not by accident. Everything I learned in school, taught me how to teach, but only after I was teaching.
I learned about “mathematics anxiety while working for the EOP program at SUNY Oswego. I will never forget the mentoring done by PP and others. They believed in a process for helping students get past their bad experiences in mathematics to a new experience of passing a math class to meet the graduation requirement. In that short almost four year experience, I learned that at any point in someone’s lives they could change. They can change their attitudes towards mathematics and build success for themselves. I learned patience, and I gained gratitude for all the teachers who had to deal with me over the years. The EOP program, and the courses I taught helped me realize that I did believe that everyone could do the math and that it was my responsibility to ensure that my practices included both emotional support, cognitive supports, and hard work reminders. Without the EOP experience, I might not have understood that there is another world out there preparing people to investigate mathematics and their place in it.
What a gift it is to be supervising student teachers. I see all of my faults in their behaviors. I see myself 30 years ago trying to figure out how to talk to the students, teach content, watch the clock and figure out why students don’t stay in their seats. There is no need to figure all of this out. The most important thing with this math thing is to trust in the students who have to learn to learn. We cannot assume they are going to make mistakes, but we can assume that when they make mistakes, that there is someone there to help learn from those mistakes. Yes, yes, we learn more from our mistakes than we learn from not pushing ourselves to the limit. I love math because it challenges my thinking, my interactions with others, and my deepest desires to know be successful.
My last post was on Nov. 17. This means two months without a post. After returning from Budapest, I wondered how my learning about math teaching in Hungary could benefit my university and the interactions I have with students at my institution. I have been asked to supervise Mathematics student teachers. What a wonderful opportunity to discuss the creative process of learning and teaching mathematics. I will have an opportunity to help the next generation of teachers find their teaching selves for the purpose of ensuring that all students can learn math well.
I attended the JMM ( Joint Mathematics Meeting) January 10-13, 2018. This is a joint conference of Mathematics Association of America ( MAA) and American Mathematics Society (AMS). Every type of (as the Europeans say) maths was presented. I attended many talks on teaching and learned about math teachers who teach University and K-12 students how to be mathematicians. In fact, Francis Edward Su has amazing writing where he shows his vulnerability around doing mathematics and teaching mathematics. I had no idea that others, certainly more high powered that I, had insecurities about their abilities, but also had the attitude of paying it forward. The paying it forward idea came through loud and clear at each presentation. The important detail is that we do not know everything there is to know about how to teach mathematics, but our passions, interest, curiosity, intentions, and attention to learning will help us move forward from where we are in our teaching.
I was asked by a researcher if I did mathematics for fun. At the time I said, “I have not done the math for a long time.” I decided to do some math because I felt like I was out of the loop. The process of doing math for oneself is important. One should consider doing math, whether it is a puzzle or a theoretical problem or a game because the process of doing mathematics keeps your brain engaged in the process of learning. If you are teaching or teaching teachers to be mathematical, it is difficult to maintain one’s credibility without actually doing math.
I tried a calendar problem from NCTM as my new entry to doing mathematics. I spent time on the problem and found it challenging, but in the end, it helped me understand how to approach my teaching and supervision responsibilities. Teaching is an interactive process, especially in math. I think that without ongoing engagement with mathematics, it is difficult to ask students to do math that is unknown, challenging, and brain expanding. The struggle of the process of doing math is part of why we should continue to do math.
I look forward to working with a group of new student teachers. I look forward to helping them see themselves as mathematicians because math teachers are created, made, not born. Each of the students has decided to become a teacher for different reasons. I am interested in helping them grow because I do math because it is challenging and I never know until the end if the answer is correct. The process and the product are equally a part of doing the math. I hope that I can help this cohort of student teachers to grow to the next level.
I am scared and excited. Making mistakes is part of the process. I hope that our learning together will be productive.
I read one of the National Council of Teachers of Mathematics (NCTM) Math Teacher
articles. I was looking for some motivation to move forward with my agenda on diversity and Mathematics for all. In the past, I have recommended that math teachers engage in personal problem-solving as part of their ongoing professional development. The premise is that by continuously placing ourselves in math problem-solving modes, we may be better equipped to support our students as they engage in the same process. These personal problem-solving activities such as, reading mathematics education articles, experimenting with math problems or puzzles, making sense of the history of mathematics, exploring art and mathematics, or investigating realistic, applied math problems.
I chose the November 23, 2017, monthly calendar problem from the Math Teacher to pursue my professional development around experimenting with math problems.
The number puzzle is from an 1852 algebra textbook: “A certain number consists of three digits, which are in arithmetical progression; and the number divided by the sum of the digits is equal to 26, but if 198 be added to it, the digits will be inverted. What is the number?”
After feeling scared that I might not be able to solve the problem, I wrote the problem down and tried to understand the problem. I then made sense of the problem by writing some examples of my understandings. I thought, since this is from an algebra textbook, I decided to try to use some algebra. After about 5 minutes of setting up some equations, I decided that it would be easier for me to follow my instincts and just try out some example cases of solutions to the problem. I then gave up a little bit and wrote some arithmetic progressions using the digits 1, through 9. I worked for about 30 minutes until I was successful.
Finding the solution was empowering. The selected problem has very little to do with an applied problem, often recommended for a performance task in math and often recommended so that student witness the value of a real-world problem. The answer is not obvious; there is more than one way to arrive at the answer or perhaps the problem has more than one answer; there is a perplexing situation that is understood; the solver is interested in finding a solution; one is unable to proceed directly to a solution; and the solution requires the use of mathematical ideas. (Find the reference.)
I felt stress and anxiety. I wondered why I was doing this. I believe it is essential for pre-service and in-service teachers to engage in problem-solving because it puts you in the shoes of the student. I had forgotten what it felt like to not know exactly how to approach any math problem. I had forgotten about the tension involved in solving a problem. If we expect students to do this, solve problems, then we have to engage the process ourselves, and students must be taught how to engage in this process.
The process of solving the problem may mirror the process mathematicians engage when discovering a solution to a theoretical question. I only felt a sense of courage and confidence about solving the problem once I solved the problem myself. The steps, the feelings, the success, the stress, and finding the answer, all might be transferable to problem-solving in general. If we expect citizens in our democracy to make decisions and solve essential life problems, then how do we use the curriculum to engage students in problems that provide them with the experiences we want them to have for the classroom and life.
Many years ago I taught a course for non-math majors (MAT102) at SUNY Oswego, a required course for majors other than math, science, business or computer science. One of the topics was Euler paths and circuits. For a youtube© link on Euler paths and circuits go to htttps://www.youtube.com/watch?v=REfC1-igKHQ. The Euler Circuit requires an even number of vertices. So what? I think this topic can be taught to Kindergarten to Grade 16 students without very much additional content preparation.
The content lends itself to real-world examples, such as a mail delivery route or creating a public transportation system, where students could use mathematical language and thinking. Students could discuss the number of paths to get from one location to another, and in the discussion use mathematical language and reasoning.
For example, I spent almost every day, in Budapest, using the public transportation system. With Budapest’s system, you can purchase a 7-day pass for 4950 forints (approximately $17.00) and travel anywhere on Budapest’s public transportation system. One day, to figure out how to get around Margaret Island, I kept on taking the bus back and forth on the Island. What a great way to make your very own tourist style HOP ON, HOP OFF. For a while, I kept on seeing the same bus driver following his route. He never said anything each time I showed the pass.
I used the public transportation system for all the school’s visits. Each of the journeys included some combination of walking, biking, trams, buses, or subway. (I never took a taxi in Budapest.) By far, my favorite mode of transit was the tram. Tram’s con, next to the electricity and run even during rainstorms. Often when I used my GPS on my mobile phone, multiple routes were provided. My technology allowed me to remember Euler.
Using a “problem-solving approach” to math teaching is difficult (as mentioned in a previous post), but the benefits of using real-world problems or theoretical problems that ignite creative thinking outweigh the challenges. Providing students with engaging problems, where students employ a democratic process for thinking, engaging with one another, and solving a problem together is at the heart of real math learning. I posit that engaging students in mathematical problem solving require a particular protocol of teacher behaviors (Sawada, 2002). Teacher behaviors should support the following student actions. Students should want to solve the problem; The solution is not obvious; There is more than one way to arrive at the answer; The problem is interesting enough that students want to find a solution; The student is unable to proceed directly to the solution; The solution requires the use of mathematical ideas.
Teaching for democracy, therefore, creates a space for citizens (our students) who have problem-solving abilities in other areas. At stake is whether we continue to teach in a way that covers the material, to students who see mathematics as a place for only negative experiences, or do we work to help students view mathematics as an opportunity to build democratic processes. Students who have problem-based experiences in math may be more confident problem solvers in general.
One of the teachers I met (I will call her Maria) is about to release her first group of students she has been working with for the last 3-4 years. (In many Hungarian schools, a group (their class) of students is assigned a single math teacher, four years. So students keep the same math teacher for grade 9, 10, 11, and 12. These students have the benefit of having a teacher who knows their mathematics strengths and weaknesses. The teacher can scaffold the learning differently, and in many cases provide the differentiation needed for each student to build their math potential.
I witnessed these particular problems, play out in two of my observations, grade 2, and grade 7 classes.
Grade 2 problem in a Roman Numerals lesson:
How do you change one stick in the equation to make the statement true?
X I + V = V
V + II = V
V – II = VII
V – I = IX
(At the end of one of class a 2nd grade girl went up to the teacher with one of the solutions. She had been given time with her peer to find a solution. Students also completed this mathematical exercise using sticks and the teacher’s role was completely different.)
Grade 7 problems related to an Exponents lesson:
For homework students were asked to create the largest possible number using five 2’s.
Which of the following numbers (brought by the students) is the largest?
a) Which number is larger, and why?
b) What is the last digit of the number. Explain?
The students in each of these classes (grade 2 and grade 7) worked in different modes, alone, collaboratively, and as a full class. The teachers did not have organized systems for the grouping expect for grouped seating. I observed student facilitation of learning as teaching.
These theoretical problems, respond to teacher objections about not having relevant enough applied problems to try the problem posing/solving approach to teaching. These theoretical problems are not contrived and are not necessarily connected to the current curriculum being taught. Theoretical problems can move student thinking forward and allow access to mathematical knowledge and processes. I witnessed democracy in action in my observation.
A ride on public transportation informs my thinking about applied problems and theoretical problems. Thank you BKK (Budapest Public Transportation system).

I have less than three days left and what do I do? I go to the market. The market is dangerous when you have a short time left because there are vegetables and meats and cheeses to buy, but you are alone and who is going to eat it? I have created a monster for my last few days. I bought popcorn and oranges and tangerines, and sausage and bacon and Brussel sprouts and onions and tomatoes. All of these things are great, but as I said, who is going to eat it? I wanted to buy eggs and cheese, but seriously, why. I also purchased some favorite desserts to which I have become accustomed. I have paid anywhere between 3200 to 1000 forints for this dessert, but today, at the market, the favorite dessert–Somloi Galuska was only 320 forints. I bought two.
Every interaction with people in the market is affirmative and engaging. I do not know Hungarian, and for the most part, they do not speak English, but we figure it out. I learned after only two months in Hungary that when it says Kilograms and you are trying to figure out if the price is right, that 1 pound is approximately 2.2 kilograms. Now I think I knew this before, but when you are in another culture, and you don’t speak the language, you forget about your school math and work double time to figure out forints to dollars and pounds to Kilograms all at the same time. The merchants could have been swindling me, but they did not/ When I give a merchant 5000 forints for something that cost 230 forints, which means I should have given the person the 500 forint note, they could just take my money and move on. They could take advantage of me, but they do not. I spent another 10 minutes trying to figure out that I did not want a blueberry extract for 6000 forints, but before I knew it there were four different sets of people trying to help me communicate that. I learned a little more about forints and kilograms today and nice Hungarian people in a market off the 4 – 6 tram and the number 19 bus.
I will remember, with affection, the experiences in the community, probably more than I remember the school visits. We have many possibilities for which we can assist our youngest and oldest students to connect better with math. I am in awe of the resilience exhibited by the Hungarian people over the last 100 year, war, fascism, communism, and democracy. They are doing yeoman’s work to figure out democracy, and so are we in the United States.
The market is where I go to learn about the culture and myself.
