Teach it
Where it is taught, with guided notes, practice, homework, an exit ticket and an interactive Teacher Deck.
Examples
- A 5% increase has growth factor 1 + 0.05 = 1.05.
- A 10% increase has growth factor 1.10.
Key rule
Add the rate to 1 to find the growth factor.
Memory hook
Growth factor = 1 plus the rate.
