1. The Need for Speed Comparing and Ordering Rational Numbers

2. What is a speedboat? A speedboat is a boat that is powered by an engine and can reach high speeds. Has anyone ever seen or been on a speedboat?

3. What is a rational number? A rational number is any number that can be written as the ratio of two integers where the divisor is not zero; for example, 8, 1.5, , and -3.

4. Comparing Rational Numbers • Compare your speedboat speed with your shoulder partner’s speedboat speed and answer the following questions. • Who’s speed is faster? or Who’s speed is slower? • Write an inequality using the two speeds. (ex. 4 >1)

5. Comparing Rational Numbers • Compare your speedboat speed with your face partner’s speedboat speed and answer the following questions. • Who’s speed is faster? or Who’s speed is slower? • Write an inequality using the two speeds. (ex. 4 >1)

6. Ordering Rational Numbers • Order all of the speedboat speeds at your table from least to greatest. • Write 4 inequalities using the speedboat speeds at your table.

7. Exit Problem Compare the following rational numbers. Order the following rational numbers from least to greatest. 3, 0.25, -6, (-24), 0.65,
