Positive and Negative Integer Number Lines Activity Sheets - Free Printable

To solve this problem, we need to place each number on its own number line.

Here is the step-by-step thinking for how to do it:

1. Understand the Number Line: Look at the lines provided. They are marked with -20, -10, 0, 10, and 20.
* The space between each big number (like 0 to 10) is divided into 10 small sections.
* This means every single small tick mark represents 1 unit.
* To the right of 0 are positive numbers (1, 2, 3...).
* To the left of 0 are negative numbers (-1, -2, -3...).

2. Analyze Each Problem:

* Problem 7: The number is -6.
* Start at 0.
* Since it is negative, move to the left.
* Count back 6 little ticks: -1, -2, -3, -4, -5, -6.
* Mark that spot. It will be just before the halfway point between 0 and -10.

* Problem 8: The number is -14.
* Start at -10.
* Move to the left because it is more negative than -10.
* Count 4 ticks past -10: -11, -12, -13, -14.
* Alternatively, start at -20 and count forward 6 ticks.

* Problem 9: The number is -1.
* Start at 0.
* Move left 1 tick.
* That first tick to the left of zero is -1.

* Problem 10: The number is -15.
* Find the halfway mark between -10 and -20.
* Counting from -10: -11, -12, -13, -14, -15.
* This is exactly in the middle of -10 and -20.

* Problem 11: The number is 2.
* Start at 0.
* Since it is positive, move to the right.
* Count 2 ticks: 1, 2.

* Problem 12: The number is -7.
* Start at 0.
* Move left.
* Count 7 ticks: -1, -2, -3, -4, -5, -6, -7.
* This is close to the halfway mark between 0 and -10.

* Problem 13: The number is 18.
* Start at 10.
* Move right.
* Count 8 ticks: 11, 12, 13, 14, 15, 16, 17, 18.
* It is very close to 20 (just 2 ticks away).

* Problem 14: The number is -12.
* Start at -10.
* Move left.
* Count 2 ticks: -11, -12.

Final Answer:
For each number line, locate the starting point (0) and count the correct number of steps based on the value given.
- For -6, count 6 marks to the left of 0.
- For -14, count 4 marks to the left of -10.
- For -1, count 1 mark to the left of 0.
- For -15, find the midpoint between -10 and -20.
- For 2, count 2 marks to the right of 0.
- For -7, count 7 marks to the left of 0.
- For 18, count 8 marks to the right of 10.
- For -12, count 2 marks to the left of -10.
