Integers Standard: Write in your notes... Integer: Positives, Negatives, {…, -3, -2, -1, 0, 1, 2, 3, …} and zero -5 -4 -3 -2 -1 0 1 2 3 4 5 No decimals, no fractions Watch the next two vocabulary words… Origin: – The point on the number line labeled zero -5 -4 -3 -2 -1 0 1 2 3 4 5 Negative Positive Origin Real Numbers: – Any number that is positive, negative, or zero Tell you partner in your own words: What is “origin” and what are real numbers? Shout out! Integer or Real Number? Real Number -5 -4 -3 -2 -1 0 1 2 3 4 5 Integer -5 -4 -3 -2 -1 0 1 2 3 4 5 With your partner… 1. 2. 3. 4. Determine who will be shoulder-partner A and shoulderpartner B Person A will name the first number in the following example Person B names the second number, then Person A the next… Name the order of all the numbers in the coming example The first number is… The next one is… Which is Greater? 5, 2, -4, 0, -1 -5 -4 -3 -2 -1 0 1 2 3 4 5 -4, -1, 0, 2, 5 Positive Numbers Negative Numbers Moving on the Number Line Choral Response + right on means a move to the _______ the number line - left means a move to the _______ on the number line Pencils down… • Watch the next two examples… • Look for patterns Practice right +3 -5 -4 -3 -2 -1 0 1 2 3 4 5 5 + (-7) = -2 -5 -4 -3 -2 -1 0 1 2 3 4 5 In your notes... • When adding two numbers with the same sign (++ or - -): Add the number and keep the sign the same Example: 5+3= -13 + (-4) = 8 -17 Story Time Armando earned $10 by doing his chores at home, and this is all the money he has. He discovers… he lost his math book!! Armando now owes the school $58 for that nice textbook. Using his $10 to start paying it off, how much more does he have to pay? Tell your neighbor how to find how much $$ Armando owes. To find the Amount of money... Mathematically, it looks like this: $10 + -$58 = -$48 Or 10 + (-58) = -48 Shout out! Example 4: Example 3: -4 +7 =3 -11 + 8 = -3 The answer is… The answer is… The answer is… The answer is… The answer is… In your notes: Write a what you think might be the rule for adding integers with different signs. Compare your definitions with your partner’s definitions. Add to your definitions or revise them if necessary. -5 -4 -3 -2 -1 0 1 2 3 4 5
