This page currently runs version 0.9.4 of the number line. If you are on Windows or Linux, you might need to use Firefox as some users have reported problems with Chrome (please let us know if Chrome does not work for you). Internet Explorer is not supported.

Note:

- Most of the number lines below are initially intentionally sparse. We want students to demonstrate their understanding by building the ticks they need to satisfy the task.
- When these are in a real assessment, they will be automatically scored. On this demo page, however, no scoring or answer feedback will occur.
- For the tasks that have 'a' and 'b' parts, only one or the other of these would be on any given test.

Create a tick mark at 4 and drag the letter A there. (Tip for those new to the number line: press and hold on the line between zero and ten until the yellow highlight appears, then choose an action.) Next, create a tick mark at -3 and drag the letter B there.

The number line below has some labels missing. Find the tick mark for 4 and place the letter A there. Find the tick mark for -3 and place the letter B there.

On this number line, you can label tick marks you create in any way you want. Create tick marks at ⅓, ¼, and ⅕. Label each of these three tick marks with the correct fraction.

The following number line is partially labeled. Place each remaining label (⅓, ¼, and ⅕) on the corresponding tick mark. (Tip: to select a wider range, press and hold until the yellow highlight appears then drag left or right.)

Create tick marks at 4/7, 3/8, and 2/5. Drag each label to the correct tick mark.

Stan owes $11 to Eddie, which he will pay back in 3 equal payments. Create tick marks and mark with a $ sign to show how much Eddie has received after the 1st, 2nd, and 3rd payment.

Create a tick mark at -2 ⅓. Place the duck there to mark it as your answer.

Step 1: Draw on paper a number line from 3 to 4 and show the approximate positions for 3.2, 3.17, 3.02, 3.20.

Step 2: On the number line below, create tick marks for 3.2, 3.17, 3.02, and 3.20. Label each of these four tick marks with the correct decimal.

Step 1: Draw on paper a number line from 3 to 4 and show the approximate positions for 3.2, 3.17, 3.02, 3.20.

Step 2: The number line below is configured to not reveal minor tick labels. Create tick marks for 3.2, 3.17, 3.02, and 3.20. Label each of these four tick marks with the correct decimal.

Step 1: On paper write an inequality for -4.72 and -4.83

Step 2: On the number line below, create tick marks for -4.72 and -4.83. Label both of these tick marks with the correct decimal.

Step 1: On paper write an inequality for -4.72 and -4.83

Step 2: The number line below is configured to not reveal minor tick labels. Create tick marks for -4.72 and -4.83. Label both of these tick marks with the correct decimal.

(Tip: partiion -5 to 0 by 50, zoom in, then partition -4.9 to -4.7 by 20.)

Using as few tick marks as possible, create the following between 0.9 and 1.0:

- A tick mark that has two decimal places. Label it A.
- A tick mark that has three decimal places. Label it B.
- A tick mark that has four decimal places. Label it C.
