Children from Year 5, 6 and 8 classes were asked to draw a number line, either from 1 to 100 or from 50 to 70, with intervals of 10 marked on the line. Teachers observed the spacing of the intervals and paid particular attention to whether children could accurately indicate the location of the midpoint.
DiagramThe number lines referred to by Jordanna can be viewed on the NCETM website.
