INTRO TO ALGEBRA INTEGERS AND ABSOLUTE VALUE Farris 2015

I can compare and order integers and find the absolute value of an expression.

A LITTLE MUSIC?

INTEGERS Positive number – a number greater than zero. Negative number – a number less than zero. Integer – any number from the set (…, -3, -2, -1, 0, 1, 2, 3, …)

Coordinate – the number that corresponds to the point on a number line. Inequality – any mathematical sentence containing.

LET’S DO IT.... Write two inequalities involving 1 and -4.

ABSOLUTE VALUE Video

ABSOLUTE VALUE The absolute value of a number is the distance the number is from zero on the number line. |6| and |-6| |6| = 6 |-6| = 6

LET’S DO IT |-8| + |-1| Evaluate |x| + 8 if x = -2
