M2.5.8 For the adult
Grids and directions
How do I tell a friend which box to look in?
What this chapter teaches
A box on a grid is named by its column, then its row, such as B3. East and west change the letter, and north and south change the number. Say the column first every time, so both people find the same box.
Three questions to ask
There is no one right wording. Listen for the idea.
- How would you tell a friend which box to look in?
- If you walk east and then south, which part of the box name changes each time?
- You face north and turn a quarter turn to the right. Which way do you face now?
After the chapter, the learner can
- Give a position on a grid by column and row
- Use north, south, east and west to describe a route
What they copy into their notebook
Name a box by column, then row: B3. North is up, east is right, south is down, west is left. East and west change the letter. North and south change the number.
