Finding distance between two points runs on subtraction and counting steps along a line. Warm up subtracting whole numbers and counting gaps on a number line, and distance on the grid becomes "just subtract."
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 To take one number away from another to find what is left.
Example: 9 − 4 = 5.
Level 1 A straight line with numbers marked in order from small to big.
Example: You can count steps from 2 to 7 on a number line.
Level 1 The number of spaces you count from one number to another.
Example: From 2 to 7 is 5 steps.
Level 1 A number that tells where a point sits on the grid.
Example: In (3, 5), the numbers 3 and 5 are the coordinates.
