Scaling
5.NF.B.5
Definition
Resizing a number by multiplying; factors above 1 enlarge, factors below 1 reduce.
Examples
- 6 x 2 = 12 — multiplying by more than 1 grows the number.
- 6 x 1/2 = 3 — multiplying by less than 1 shrinks the number.
Key rule
Multiplying by more than 1 makes a number bigger; multiplying by less than 1 makes it smaller.
Memory hook
Bigger factor grows it, smaller factor shrinks it.
