1 HOW TO SAVE WATER: What happens if we do not turn off the tap on time? Noèlia Callau Codorniu March 2008 LESSON 4

2 We are 16 pupils. HOW TO SAVE WATER: What happens if we do not turn off the tap on time? Noèlia Callau Codorniu March 2008

4 HOW TO SAVE WATER: What happens if we do not turn off the tap on time? Noèlia Callau Codorniu March 2008

5 16 pupils equal 16 minutes. 16 x 1= 16 min. (16 pupils multiplied by 1 minute is 16 minutes) In 1 minute, L come out of the tap. 1 L= 1000 mL.3 L= 3 X 1000 = 3000 mL L = 3 L and 450 mL mL mL = 3,450 mL.

6 If in 1 minute 3,450 mL come out of the tap, in 16 minutes … 3,450 X 16 = … mL 3,450 X ,200 3, ,0004, , ,0002, ,700 55,200 mL = 55 L and 200 mL HOW TO SAVE WATER: What happens if we do not turn off the tap on time? Noèlia Callau Codorniu March 2008
