Idea 10of 13Builds onSlide a point
Describe the slide
How do you say how one point slid to another?
Today you'll discover
- how to compare two points
- which way is right, left, up and down
- how to write the slide in words
Think firstA is at (4, 13). B is at (2, 8).
How did A slide to B?
Decide first, then press Next. Compare the first numbers, then the second numbers.
A coordinate grid with seven points: A (4, 13), B (2, 8), C (7, 3), D (4, 6), E (8, 9), F (12, 11) and G (13, 7). Step by step, L-shaped arrows go from A to B (2 left, 5 down), B to C (5 right, 5 down), and C to D (3 left, 3 up), and each slide is written beside the grid.

The big idea
Count from the start point to the end point: across first, then up or down.
Easy to get wrongThe move is the difference between the numbers, not a coordinate. From 13 down to 8 is 5 down, not 8 down.
Key word
- unit
- one square's length on the grid: 5 units down means 5 squares down
Ready to use it?
- Describe the slide from one point to another.
- Say how many units right or left, and up or down.
