CHAPTER 01 ★ START!
CHAPTER 01 · 1.1THE BIG ONEPAGE 04
means three out of four parts, like 3 slices of a 4-slice pizza!
if you eat 3 slices and your friend eats 1, you ate 3/4 of the pizza. they ate 1/4. together = 1 whole!

CLASS · OCT 14, FIRST PERIOD
CHAPTER 01 · 1.4BEFORE · AFTERPAGE 07
what I thought vs what's actually true
✗ BEFORE
bigger number = more
I thought 1/8 was bigger than 1/2 because 8 is bigger than 2 (oops!)
✓ AFTER
smaller pieces = less!
if you cut a pizza into 8 pieces, each piece is tinier than if you cut it into 2.
