THE NUMBER LINE Lesson 4

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

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

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

Comparing #s on the Number Line Which number is greater?><=

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