WHY DO we need to measure?

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
