Ruler Centimeter

How long is a centimeter? Can you draw a ladybug that’s two centimeters long? Practice measurements with this fun and engaging virtual centimeter ruler.

Use the online centimeter ruler to measure lines, drawings, and more! Measure to the millimeter by tapping the “Milli” button. Measure to the centimeter by tapping the “Centi” button. Move the arrow on the right side of the ruler to measure an object. The correct measurement will show on the screen. Toggle the measurement on and off by pressing the “Centimeter ON/OFF” button. Draw lines or objects by tapping the pencil button and then drawing on the screen. Use the eraser and trash can tools to erase your drawings.

How can you use the virtual centimeter ruler tool? Here are a few activities to try:

• Ask students to show a certain measurement, such as 3 cm or 7 cm, on the ruler by moving the arrow.
• Ask students to draw an object that’s a certain measurement. For example, ask them to draw a rectangle that’s 4 cm long.
• Have students work with a partner. Ask one of the students to draw an object that the other has to measure.
