                   He says it is almost 3 cm long.

                   (a) Is Luke correct?

                   (b) Explain your answer.

                   of an object like the blue bar accurately.


               4. What is the length of the green bar?






                    0     1    2     3     4    5     6     7    8     9    10


                  The easy correct way to use the
                  ruler is to put one end of the object
                  that you measure on the 0 mark of
                  the ruler. Read the measurement
                  where the other end of the object
                  is.
