Learning Target I will understand that relationships between quantities can be compared in different ways.
Launch Can you think of any commercials that compare one product to another? https://www.youtube.com/watch?v=pt2O-LPzX4g Can you think of any commercials that compare by using numbers? https://www.youtube.com/watch?v=V_gGAPOZbFA
Launch http://dashweb.pearsoncmg.com/main.html?r=15469&p=642 Statements: • 10 more people prefer Cola Nola than Bolda Cola • 2/3 of the people surveyed preferred Cola Nola Why did they end up with two different conclusions from the same survey results?
Problem 1.1 A Question 3 • The ratio of 17, 139 to 11, 426 THINK: round to compatible numbers 17 139 rounded up to 18,000 and 11, 426 rounded up to 12,000…what is that reduced? • The ratio of 3 to 2 (a part to part comparison) could also be written as 3 to 5 ( a part to whole) comparison. 3 to 5 is 60% • The difference between 17, 139 and 11, 426 is 5,713.
Problem 1.1 A Question 4 • 1.5 times as many people preferred Bolda Cola to Cola Nola (like the Samsung commercial made a comparison) • 6 out of 10 people preferred BoldaCola to Cola Nola
Problem 1.1 A Question 4 • Remember: 60% means 60 out of 100
