Students in some countries do
multiplication like this.

Students attending schools
in the
Burlington School District come
from over thirty different
countries worldwide. Each student
brings a unique way of thinking and
reasoning mathematically as well as a variety of different computational
techniques and strategies. We can help students adjust to "American
math" better if we understand the math they have been
experiencing in their lives before coming to the US. Some children as old
as 12 may have never studied math while others may have studied
significantly more the students 9in US schools. |
What is
Ethnomathematics?
Ethno-mathematics is the branch of math that
explores the relationship between mathematics and culture. This may
include the way societies and cultures use mathematical symbols,
procedures, methods of calculation and computation as well as the way
mathematics is defined. It can also include the way math is taught in
school in terms of whether students are tracked for math at an early age,
are required to take rigorous tests, are expected to understand what they
learn as well as the role of parental influences on student learning and
schooling in general.
The study of mathematics is
also intricately related to the indigenous language/s of a particular
country or culture. The different conceptual constructs, vocabulary and
sentence structures all influence the way we calculate, compute and reason
mathematically.
Some examples of
ethnomathematics
-
Some groups of people in
the Amazon basin, for example, have only three counting words, 'one',
'two', and 'many'
-
In Bosnia, students still
use the equal addition method to do subtraction algorithms.
-
The math program
Singapore Math is based on the national math program in Singapore
which topped international math scores in the TIMMS report several
years ago. The program is extremely rigorous and tracks students based
on annual exams from a very young age.
Here are some some sources
for learning more about this fascinating aspect of mathematics.
