### Dividing integers web

1. 1. DIVIDING INTEGERS
2. 2. BELL RINGER EVALUATE WHEN X = 5 AND Y = -1 • 4 + x + y • (x + 5) ÷ 2 • x – y + 3
3. 3. BELL RINGER EVALUATE WHEN X = 5 AND Y = -1 • 4 + x + y • 4 + 5 + (-1) • 9 + (-1) • 8 • (x + 5) ÷ 2 • (5 + 5) ÷ 2 • 10 ÷ 2 • 5 • x – y + 3 • 5 – (-1) + 3 • 5 + 1 + 3 • 9
4. 4. WHERE WE WERE… • Adding and subtracting Integers • Properties of addition • Properties of equality • Order of Operations • Multiplying Integers
5. 5. WHERE WE WERE… • Explain to your partner why the answer is positive or negative… • 4(-5) • -4(5) • -4(-5)
6. 6. WHERE WE WERE… • Explain to your partner why the answer is positive or negative… • 4(-5) • Negative – opposite signs • -4(5) • Negative – opposite signs • -4(-5) • Positive – same signs
7. 7. WHERE WE ARE… • Students will learn to… • Use counter chips to solve division of integers. • Determine the rules for dividing integers.
8. 8. • 6 items split into groups of 3 • Use the Counter Chips to model 6 items split into groups of 3 • 2
9. 9. • The opposite of 6 items split into groups of 3. • Use the counter chips to model the opposite of 6 items split into groups of 3. • - 2
10. 10. • 6 items split into groups of -3 • Use the counter chips to model 6 items split into groups of -3 • -2
11. 11. • The opposite of 6 items split into groups of -3. • Use the Counter Chips to show the opposite of 6 items split into groups of -3. • 2
12. 12. QUICK WRITE WHAT ARE THE RULES FOR MULTIPLYING AND DIVIDING TWO INTEGERS? Multiplying • 3(2) = 6 • 3(-2) = -6 • -3(2) = -6 • -3(-2) = 6 Dividing •
13. 13. RULES • Multiplying Integers • Positive x Positive = Positive • Positive x Negative = Negative • Negative x Positive = Negative • Negative x Negative = Positive • Dividing Integers • Positive ÷ Positive = Positive • Positive ÷ Negative = Negative • Negative ÷ Positive = Negative • Negative ÷ Negative = Positive
