A pet store has 4 cat treats for every 5 dog treats. Which ratio could also represent the treats in the store? Note: Rates Repeat

• 12 : 10

• 7 : 15

• 20 : 25

• 4 : 9

How much money would it be for 2, 3, 5 and 10 cokes?

Unit Rate - Per 1

1 Coke Per $2.00

• $2.00, $3.00, $5.00,

  and $10.00

• $4.00, $6.00, $10.00, and $20.00

• $3.00, $5.00, $7.00, and $9.00

• NOT here

3 12 48 192

What factor (pattern) did it change from the first number to the next number and the next number?

Note: What is being multiplied by from 3 to 12 and 12 to 48?

• 4

• 9

• 6

• 10

What is a Ratio?

• Conflict of qualitative reasoning

• per 1

• Comparison of two quantities through division.

• rates repeat

What is Rate?

• They Repeat

• Per 1

• Per 100

• Comparing two quantities through division.

Unit Rate means ?

• Per 100

• Per 1

• They Repeat

• Comparison of two quantities through division.

Look at the paper. Is this table (additive or multiplicative?).

How did the 2 get to 8?

How did the 3 get to 12?

Is there a pattern?

• Additive

• Multiplicative

Which equation goes with this table?

y = ?

Again, how do you get from 2 to 8? 3 to 12? 4 to 16?

• y = x + 4

• y = x + 2

• y = 2x

• y = 4x

What percent is shaded?

• 15 %

• 85 %

What is % (percent) mean?

• Comparison of two quantities through division
