This document summarizes a student project where they collected and analyzed garbage data from various organizations. The students visited a local aquarium and station to collect garbage, then calculated the total amount, averages, and percentages at school. They created bar graphs to display their findings at a school expo on May 17th and 18th. They practiced various math skills like perimeter, area, rounding, percentages, and the rule of three.

3. Em vez de analisarmos os
dados fornecidos por
entidades diversas,
resolvemos recolhê-los.
Instead of analysing data
from several
organizations, we’ve
decided to collect them.

4. Fomos à E.L.A. onde
cada aluno pesou o lixo
que recolheu
We went to E.L.A.
(Littoral Station of
Aguda) where each
student weight the
garbage they collected.
Of course we seized the opportunity to visit
the aquarium.
Claro que aproveitamos para visitar o aquário

5. Já na escola, em
Apoio ao Estudo,
calculámos:
• o perímetro e a área de um
talhão;
At school we
calculated:
• the perimeter and the area of
each field

6. calculámos:
we’ve calculated:
• a quantidade total de lixo recolhido;
• The total quantity of the garbage
collected;
• a média aritmética.
• The arithmetic average.

7. Cada aluno:
Each student:
relembrou os arredondamentos
e calculou
a percentagem do lixo
que recolheu.
Remembered mathematical rounding
and calculated the percentage of
garbage they collected.

8. Foi ainda feita a abordagem à
ferramenta “regra de 3
simples”, para
We also approached the rule
of three to…

9. Ainda…
Still...
construíram gráficos de barras
usando papel milimétrico…
... constructed bar charts using
millimiter paper...

no
RUMOS

RUMOS, an
expo that happend at our
school on MAY 17th and
