Transforming Math - Sunday Keynote at Confratute
Our first keynote at Confratute was about math instruction. Rachel McAnallen is a national treasure who completed her PhD at the age of 75 at the University of Connecticut. How inspiring! If you get her to visit your professional development or school, consider yourself lucky. I attend Rachel's keynotes every year. The first time I heard her speak it transformed the way I think about and teach math - and I've always loved the subject. Rachel does research on math anxiety in teachers, and the impact on instruction. Take a moment to check out her website - Zoid and Company. The blurb below is the summary of her keynote that I wrote for the Confratute newsletter.
Rachel McAnallen, known as Ms. Math to students and teachers
around the world, helped kick off Confratute in style. According to Sally Reis,
who introduced her, Rachel’s keynote addresses have marked a “turning point in
the way we think about mathematics” to attendees for years. Rachel began her
address by pointing out that math is “elegant in its simplicity”, but that her
focus for her talk would be change. Almost all of us keep up with changes in
technology. None of us still uses a rotary dial phone or a bag cell phone, do
we? Yet we complain about the changing way we teach math by saying, “That’s not
how I did it when I was in school.” It is time to alter that philosophy and
embrace a way of teaching math that helps students build a deeper understanding
of the very foundations of mathematics – place value, number sense, and
creative problem solving.
As Rachel pointed out using examples across all the
operations, we must teach students that they are in charge of the numbers. We
learned about renaming numbers in many ways to allow us to solve problems using
number sense, modeling subtraction after shopping, and using the situation of a
problem to help us decide how to define a remainder. As long as we follow the rule “respect the
decimal”, we are free to play with numbers and discover the beautiful patterns
within. This creative problem solving helps us uncover more than one way to
solve a problem and reinforces our innate sense of the value of numbers.
“Arithmetic”,
Rachel declared, “is answering the question. Mathematics is questioning the
answer.” Show the beauty of the interconnectedness of mathematics to help
develop number sense and global comprehension. Take the pledge with us now, “I
will ALWAYS respect the decimal!” Let’s take what we’ve learned back to our
classrooms and create a generation of mathematicians, not calculators.
