Measuring length to the nearest centimeter means we just give the length as "about 5 cm" or maybe "about 8 1/2 cm" instead of checking the exact millimeters.
In this lesson I show how to use a centimeter-ruler to measure how long pencils or lines are. Mathy and I also ESTIMATE the length of some pencils before checking with the ruler how long they are in reality.
Lastly we figure out how much taller some chess pieces are than others. :)
