This section describes what arguably is the key aspect of mathematics education: the teaching and learning that takes place in schools or as a result of in-school activities. Section 4.2 addresses planning. It raises some of the questions that must be answered within an individual school before class groups are formed and timetables drawn up; it also considers the problem of time allocation to different topics in a given class. From Section 4.3 onwards, the focus moves to actual classroom activities.
Section 4.3 describes the active learning that is a recurrent theme of these Guidelines. The sections that follow contain the collection of lesson ideas contributed by teachers. Most of the ideas are grouped by topic area, so Sections 4.4 to 4.11 deal with the areas into which the content sections of the syllabuses are divided. Some cross-curricular themes are presented in the remaining sections. The suggestions in Section 4 are complemented by a list of resources forteaching and learning that appears as Appendix 3.
