At Two
Rivers we have made a conscious effort to change the way that everyone thinks
about, talks about, and engages in math.
We have shifted the expectations to place the emphasis away from just
memorizing math facts to also understanding the math. We have shifted from pushing students to memorize lots of
algorithms so that they can solve specific kinds of problems on tests to
applying the math concepts they understand to solve any complex math
problem. We have shifted from a
school where it was OK to say, “I’m not really a math person” to a place where
everyone celebrates working hard to solve a math problem.
The
foundations of this shift can be described in six shared expectations for math:
1. Math is fun. 2. All students
can learn math. 3. We have a common approach to problem
solving. 4. We value multiple representations. 5. We value concise and precise communication. 6. We value reasoning and proof. These six expectations, shared publicly
with staff, students, and families, codify our beliefs about mathematics and
have made the shift in the culture of numeracy at our school real.
1. Math
is fun: Time is
built into lessons to play with math.
I don’t
recommend to anyone that they ever lie.
In fact, I encourage people to tell the truth. Math is hard… or at least it can be. However, being difficult is a long way
from being impossible, and there never is a reason to say, “I can’t do
math.” First this statement is a
gross overgeneralization. Everyone
can do math. Second, it only
reinforces negative stereotypes about math and math ability that can become a
self-fulfilling prophecy for our children.
Instead, I
recommend that we start from a place of positivity. Math is fun.
Spending time working on something that is challenging leads to huge
rewards as you discover the underlying patterns and, yes, beauty of the
mathematics. Simply shifting our
orientation in the way that we talk about math has huge benefits.
2. All
students can learn math: Every student has the capacity to learn deeper
conceptual knowledge in mathematics.
The
emphasis here is in two places.
First I mean ALL students when I say all students. I mean special education students with
IEPs. I mean English Language
Learners. I mean students who
qualify for free or reduced price lunches because their household income is
below the poverty line. I mean
girls as well as boys. I mean all
students.
Second is
that learning math is not just learning a set of algorithms. Instead we mean, that students learn to
not just compute fluently, but also to understand the mathematics that they are
working with and to apply it to appropriate situations.
3. A
common approach to problem solving: We use the K-W-I to teach steps to
problem solving in and outside of math.
To aid
students in developing the strategic competence to solve any problem that they
face, we utilize a common approach to problem solving across the school, both
in and out of math classes. This
approach emphasizes three key points.
First we work for students to first understand the problem by describing
what they know. Then we have
students describe what they need to find out. Finally, before problem solving they identify ideas for how
they might approach the problem.
By slowing students down and using the same process with every problem
we face, students develop a habit of mind towards all problems that emphasizes
first understanding a problem before searching for answers.
4. Representations: We value the multiple ways that ideas
can be modeled or demonstrated and encourage making connections between various
representations.
As students
work and produce final products in mathematics, we don’t value one way of doing
things over another. Rather the
emphasis is first on understanding.
Students utilize representations of mathematics whether manipulatives,
drawings, or numbers to understand and solve the problems. No one representation is valued over
another.
Once a
student feels confident in their understanding of their work, we then shift the
emphasis to communicating.
Students explore whether or not their representations clearly express
their understanding of mathematics for their classmates, teachers, and often an
outside audience. If not, they
revise their representations to better express their understanding to others.
Only after
we have ensured that students understand the problem and have communicated
their solution effectively do we shift our attention to whether their solution
method and representation was efficient.
5. Concise
and precise communication: We reinforce precision and brevity during
class discussion.
With the
question of efficiency, we push students to utilize accurate vocabulary and
language to express their ideas.
As students explore ideas as a class, we have opportunities to reinforce
concept development and vocabulary learning as we refine the way that we talk
about mathematics.
6. Reasoning
and proof: Mathematical arguments are weighed on the merits of their logic
NOT on the status of the speaker or beauty of the language.
Last but
not least, we emphasize that it is logic that is weighed most heavily in our
classrooms. As many of us know,
many arguments are won by the popularity of the person speaking or the complexity
of the words that he or she uses.
However, we want students to develop a critical ear for arguments that
places value on what makes sense.
It is with
these six expectations for how students, staff, and families engage in
mathematics that we have created a foundation for changing the culture of
numeracy at Two Rivers.
