Supergravity:
About to Occur!
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

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.
