Integers and absolute value sit on a number line. To get them, you need to count steps from 0 in both directions and understand opposites (left/right). Warm up the number line and "how far from zero" feels natural.
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, with 0 in the middle.
Example: On a number line, you can count steps left or right from 0.
Level 1 How far apart two things are.
Example: The distance from 0 to 5 is 5 steps.
Level 1 Going the other way; the reverse direction.
Example: Left is the opposite of right.
Level 1 To take one number away from another to find what is left.
Example: 8 − 3 = 5.
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. How many steps is 5 from 0 on a number line?
2. Which direction is the opposite of moving right?
