 Measurement

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 foot304 mm Avg length of Chinook Salmon 700 mm Length of Mr. Kemball’s classroom 7620 mm Earth to Moon384, 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 foot30 cm Avg length of Chinook Salmon 7 dm Length of Mr. Kemball’s classroom 7.62 m Earth to Moon384, 000 km Earth to Alpha Centauri (nearest star after the sun) 4.24 light years
