IWBAT compare and order positive and negative numbers.

Numbers get larger from left to right.

IWBAT add and subtract integers.

Adding two positive numbers (Normal adding) *Integers without a sign are positive Adding two negative numbers (Normal adding but answer is negative) Adding a positive and a negative number (Subtract numbers and take the number with the larger absolute value Absolute Value – The number of spaces an integer is away from zero. Adding Integers

1) ) ) ) *A negative sign is the same as subtraction = )

1 Convert into addition problem 2 If just subtraction sign, squeeze in an addition sign to the left. 3 If subtraction sign AND negative (double negative), merge to make an addition sign.

1) ) ) ) ) )

IWBAT multiply and divide integers

IWBAT write and evaluate algebraic expressions with integers

 Algebraic Expression – a math sentence that contain a variable but does not have an equal sign  Input Table – A table that gives you numbers to input (substitute) and results in a patterned output
