1. THE NUMBER LINE Lesson 4

2. Math Vocabulary Number Line – a line that has numbers arranged in order from least to greatest Origin – point 0 on the number line (aka: the starting point) Integer – a whole number and its opposite

3. The Number Line NegativePositive _______________________________________________ Point of Origin #s less than zero#s greater than zero  same # order but typical # order but  decrease in sizeincrease in size

4. Examples… _______________________________________________ A = R = -9 B = S = 2 C =T = -12

5. Comparing #s on the Number Line Which number is greater?><= -2 6 3 0 -3 0 14 -14 -12 5

6. Practice ___________________________________________________ Draw and label the following points on a number line: 1. A = -3 2. B = 6 3. C = -10 Compare = 4. -5 5 5. 0 -8 6. -4 2
