The Maths Habit Handout to print

You are at the dot. How would you tell someone the way to the star?

Along 4, then up 3. If everyone goes along first and then up, 4 then 3 always means the same place.

Coordinates
Two numbers that give the position of a point on a grid.
Origin
The corner of the grid where the numbering starts.
Plot
Mark a point on a grid with a small cross.

Along the corridor, then up the stairs.

  1. Start at 0.The corner where the numbers start.
  2. Along the corridor: how far along?Along the bottom first.
  3. Then up the stairs: how far up?Straight up to the point.
  4. Write (along, up).A is at (4, 3)

Which number tells you how far along?

(5, 2) 5: the first number is along

Which number tells you how far along?

(0, 7) 0: you do not move along at all
