For example
In the pair (3, 5), the first coordinate is 3 steps across.
In Grade 5
Children plot points on a grid, saying the across number before the up number every time.
Watch out for
Children often reverse the two coordinates. Across comes first and then up, so swapping them lands somewhere else entirely.
Say it at home
Play a grid game and insist that the across number is said first.
