Teach it

Where it is taught, with guided notes, practice, homework, an exit ticket and an interactive Teacher Deck.

Examples

  • Rise 3, run 4 gives a slope of 3/4.
  • Count the rise first (up/down), then the run (always to the right).

Key rule

Slope = rise ÷ run.

Memory hook

Count up, then count over.
