             This piece  of string      :?     t...
             is 1 decimetre  tong.
            It also measures                     ~IL            2 I   3 I  I  4  I  5  6 I   7 I  8 I  I  q   ioI

            rn Using this string for comparison,                  estimate how many
                  centimetres       long the strings below are. Keep your ruler hidden!


            00 Write your estimates              on the chart.
            00 Afterwards,         find your ruler and measure the lengths
                  of string.

            ~     Complete the table by finding the difference
                  in length between your estimate and
                  your measurement.
