  3. Adding positive and negative numbers using a number line: Add 6 + -8 -3 -2 -1 0 1 2 3 4 5 6 7

  4. Adding positive and negative numbers using a number line: Add 6 + -8 start -3 -2 -1 0 1 2 3 4 5 6 7

  5. Adding positive and negative numbers using a number line: Add 6 + -8 start 6 units right -3 -2 -1 0 1 2 3 4 5 6 7

  6. Adding positive and negative numbers using a number line: Add 6 + -8 start 6 units right -3 -2 -1 0 1 2 3 4 5 6 7 8 units left stop The sum is -2

  7. Add using a number line. • 2 + -5 • -8 + 3 • 4 + -9 • -7 + -3
