Lesson 2.2.6Multiplying Fractions and Mixed Numbers

SUPERGRAVITYAs a roller coaster reaches the bottom of a slop and

begins to go up the next slope, it’s acceleration, combined with the downward pull of gravity, can make you feel 3 ½ times as heavy as you really are!

This sensation is calledSUPERGRAVITY!

Reading Problem –

As a roller coaster car reaches the bottom of a slop and begins to go up the next slope, it’s acceleration, combined with the downward pull of gravity, can make you feel 3 ½ times as heavy as you really are!

This sensation is called SUPERGRAVITY!

How heavy would a 120 pound person experiencing Supergravity feel!

Answer

Multiply 3 ½ × 120 pounds =

I would feel…. 420 pounds…. WOW!

Why do we need to learn how to multiply fractions?

Are you a…… Chicken

- OR -

Brave Heart

Using math to calculate how I would feel during“Supergravity” would convince me NOT to go on

the ride!

Over the past several days we have multiplied fractions using visual models. Today, we will learn a more traditional method to multiply fractions and mixed numbers. Let’s get started!

Today’s Lesson

Not handling super gravity very well.
