This guide is the seventh of a series of seven curriculum guides included in SE 012 723, SE 012 724, and SE 012 725, and concludes the primary school mathematics course (grades one through six in Victorian schools, Australia). It is expected that "a substantial majority of children leaving grade six will have completed Section H. Some children will have had experience with Section I, while others will not have reached Section H." Perhaps for this reason, the majority of the activities suggested for these two sections are designed to produce deeper understanding of the previous material through extensions and further applications. New topics include rounding off, multiplication of fraction by fraction and of decimal by decimal, ratio and percentage, rotational symmetry, and histograms and averages (mean, mode and median). (MM)
