Find an object in or around your house that is approximately each of the following measurements long. After measuring the object, write the name of the object next to the measurement it’s closest to in length and record the exact measurement of the object (remember to measure to the tenths place!).
Target Measurement Object Actual Measurement
1 cm
2 cm
3 cm
etc.
You could also have students guess which measurement their object will be closest to before measuring.
If you have students who might not have a centimeter ruler at home (or at least claim that they don’t), you can print off paper rulers here.
Check their accuracy after photocopying, just to make sure. Mine have worked out well in the past.
