Many people have several things they excel at, some more
than others. Canadians use the four main math operations every single day, but
most people don’t do it the same. Maybe they were taught different, maybe they
figured out different ways to do their subtraction, addition, division and multiplication
in their own way. In the past, our math curriculum as based on several
different rules, the same can be said about teaching and using the four math operations.
But if everyone is different, wouldn’t it make sense to provide students with alternative
ways to learn and do math?
Students
often struggle with the real world practicality of the math they learn; the
common notion is “why am I learning all of this stuff? I’m never going to use
it again.” In recent years, educators have focused on creating real-world exercises
and problems for students to do, in order to show them that math is everywhere,
and they will use it every day. The phenomenon of incorporating open questions into
math is crucial to sparking students imagination, and can be used a great
teaching tool at any grade level. But what about the basics, the foundations to
all math taught early on in students education, isn’t that all the same? If
everyone is different, would showing them one way suffice all students? Should
we as educators just aim to “suffice” or should we show them many ways and let
them develop their own tactics?

What educators
ought to do is allow students to build their own foundations early on, believing
in the idea that students will be able to develop their own algorithms for the
four operations after they have identified the “facts” of math. Educators must
first start with having students realize the crucial facts within math operations,
specifically the multiplication and addition time tables. Within these facts,
educators can highlight key facts, useful facts that will allow students to
build a base for their procedures and algorithms. Students must start with the
facts, then begin to build their knowledge about the various relationships
within the operations, supported by the educators guidance.
An
example of learning the facts, then building onto them would be realization of
the commonalities within the multiplication table. If students know that 2 x 3
= 6, then it is possible for them to estimate what 20 x 30 would be. Knowing the
simple facts is crucial for a student’s future to build onto their understanding
within the four operations. It is important to acknowledge that the age where
we as educators rewarded the speed at which students learn and complete the
facts is gone. Educators must now focus on being flexible when it comes to
students learning the facts, and teaching them about the inter-relations. Too
often in the past, students memorized sets of number combinations without
really understanding them.
The
future of math is based on educators commitment to showing students all the tools
and letting them pick which ones they want to use. Student’s don’t have to use
every tactic their teacher shows them, as well as they do not need to use the
same procedure forever. Students will often leave behind things they have
learned because they do not need them anymore or because they have realized or
been shown another way to do it. The image below shows a procedure that helps
students add large numbers without the use of a device. The tactic is often
called “skip counting”, and is based on the students knowing that a number like
332 can also be shown as 300 + 30 + 2.
The
purpose of this post was to shed light on the fact that math is not the only
subject that has rigid rules to follow, it too should be fluid and allow for
all students to be able to learn their way and with a better pace. Educators
must allow students to do what they feel most comfortable with when it comes to
the development of various algorithms and procedures. Educators must take this
in stride, so they can show all students that math is sensible, useful and
do-able.
