Minds-on
What would happen if we did not have common standards for measuring?
Is there a need for a common unit of measure?
Lets introduce one common unit for
measuring! Mr. Samji’s foot 304 mm
Avg length of Chinook Salmon
700 mm
Length of Mr. Kemball’s classroom
7620 mm
Earth to Moon 384, 000, 000 mm
Earth to Alpha Centauri (nearest star after the
sun)
44, 500, 000, 000, 000, 000, 000 mm
THINK- PAIR- SHARE
Is it efficient to have only 1 unit of measurement for Measuring distances at all scales???
Does this make more sense?
Mr. Samji’s foot 30 cm
Avg length of Chinook Salmon
7 dm
Length of Mr. Kemball’s classroom
7.62 m
Earth to Moon 384, 000 km
Earth to Alpha Centauri (nearest star after the
sun)
4.24 light years
