Before you graph points anywhere on the coordinate plane, you need the basics solid: read a number line, and plot a point by going across (x) first, then up (y) in the first quadrant. Warm those up and graphing clicks.
These are words you'll need to already know to follow this lesson — not the new words the lesson teaches. Review each one, its meaning, and the example so the new lesson makes sense from the start.
Level 1 A straight line with numbers marked in order from small to big.
Example: On a number line, 3 sits to the right of 2.
Level 1 A pattern of squares made by lines that cross.
Example: You can count the squares on a grid to find a spot.
Level 1 Moving left or right, side to side.
Example: Move 3 across to the right before you move up.
Level 1 Moving higher, toward the top.
Example: After moving across, move 2 up to reach the point.
These check the skills you'll need for this lesson — not the new lesson itself. Answer all 3, then press Show my path. No grade — it just suggests where to start.
1. On a number line, what whole number sits exactly between 2 and 4?
2. To plot a point, which do you do first?
3. A point is 3 right and 2 up from (0,0). What are its coordinates?
Vocabulary previewed and basics checked. Time to start the lesson.
