Teachers are free to plan their own lessons, but there are some well-established practices to build on. The following proposals are based on these practices.
In GRADE 3 MATHS, the NUMBERS area continues the work on written and mental calculation, and the first column methods for addition, subtraction and multiplication can be presented, useful when horizontal calculation becomes hard. Some properties of natural numbers and of the operations are investigated, also to make calculation easier. Division is introduced through sharing and grouping situations and linked to multiplication; fractions and decimal numbers are first discussed. Operations, also with decimals, are practised in contexts such as buying and selling. In the second part of the year, a first approach to algebraic symbols can be proposed in meaningful contexts, using symbols to stand for unknown numbers or to express relations.
In the SPACE AND FIGURES area, straight lines (with attention to parallel, intersecting and perpendicular lines) and angles are introduced, and pupils learn to recognise and classify them. The classification of polygons is taken further, with equilateral, equiangular and regular polygons. Perimeter and area are first discussed, comparing and measuring outlines and surfaces, also with non-standard units. Alongside drawing on paper, pupils build physical models of plane and solid figures.
In the LOGIC area, work on quantifiers continues and predicates, negation and connectives are introduced, also with reference to computer science. With this in mind, pupils take their first steps in programming: they write simple programs (for example with visual block-based languages) and check, by running them, whether they do the intended task, fixing any errors.
In the RELATIONS, DATA AND PREDICTIONS area, fractions are used to describe simple probabilities. Some more complex combinatorics activities can be tackled. Pupils read and interpret data shown in tables and charts. Units of measurement for length, weight, capacity and time are discussed, introducing conversions between units.
PROBLEMS are tackled, with attention to their meaning and to explaining and comparing solution strategies. As well as problem solving, pupils work on problem posing.
Below you will find maths activities grouped by topic area, though the grouping is not meant to be rigid. The proposed activities are part of the pathways available in the tables of the primary school maths section.
