1
IWBAT compare and order positive and negative numbers.

2
Numbers get larger from left to right.

3
IWBAT add and subtract integers.

4
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

5
1) 2 + -7 7 - 2 5 -5 2) 5 + 3 8 3) -4 + -8 4 + 8 12 -12 4) 9 + -5 9 - 5 4 *A negative sign is the same as subtraction 9 + -5 = 9 - 5 5) -12 + 2 12 - 2 10 -10

6
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.

7
1) -3 - 7 -3 + -7 3 + 7 10 -10 2) 1 - -8 1 + 8 9 3) -7 - -7 -7 + 7 0 4) 5 - -5 5 + 5 10 5) 8 - 10 8 + -10 -2 6) 0 - 7 0 + -7 -7

8
IWBAT multiply and divide integers

11
IWBAT write and evaluate algebraic expressions with integers

12
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

13
1) 5 – 3(2) 5 – 6 2) 5 – 3(-1) 5 – (-3) 5 + 3 8 3) 5 – 3(-4) 5 – (-12) 5 + 12 17 n5 – 3n 2 -4 n5 – 3n 2 8 -417
