Choose from a variety of activities. There are 2 types of activities. The tile activities test the students' knowledge of where numbers should be on several different number lines, which may have different scales. There are 10 sets of tile activities and 4 sets of draw activities. In draw activities, you can draw automatically measured lines on the number line. These special number lines can also be used to model addition and subtraction. (Printable activities at the bottom of the page)

Suggested Lessons or Activities:

The draw activities can be used to strengthen the concept of scale on a number line and where numbers belong in relation to each other. Help your students draw a connection between a number line and the axis of most common graphs that have linear scales.

The draw activities can be used to model addition and subtraction. For example, mark two points on the number line (e.g., 9 and 20). As you draw a line to connect these two points the distance between them shows up in the floating text box which is the difference between the numbers. Ask the students to write the related number facts (9+11=20, 11+9=20, 20-11=9. 20-9=11).

Hide the details (sub-divisions) on the number line to see how well students can estimate the positions of the numbers.

The tile activities can be used as test or practice to see if students have mastered the skills.

Special Features:

touch friendly (e.g., In draw activities, your finger can be anywhere on the screen when you are drawing the lines. This way your finger doesn't cover the line you are currently drawing.)

number tiles are rejected if misplaced

When you click a number tile, it will come to the front (highest level or depth above all other tiles).

automatic measurement of the lines you draw on the number line

can hide and show the subdivisions of the scale on the number line in draw activities. This is great for estimation activities.
