The Mathematics Curriculum in Primary and Lower Secondary Grades
The mathematics learning area for both English- and Māori-medium education has three strands: Number and Algebra, Measurement and Geometry, and Statistics. New Zealand only assessed students in English-medium settings in TIMSS 2015, therefore the following summary details Level 3 of the English-medium curriculum, with additional details provided by the National Standards.k
The majority of students should have been introduced to or taught each of the following topics or skills by the end of Year 5:
- Number and Algebra—Use a range of additive and simple multiplicative strategies with whole numbers, fractions, decimals (simple), and percentages; know basic multiplication and division facts; know counting sequences for whole numbers; know how many ones, tens, hundreds, and thousands are in whole numbers; know fractions and percentages in everyday use; find fractions of sets, shapes, and quantities; record and interpret additive and simple multiplicative strategies using words, diagrams, and symbols, with an understanding of equality; generalize the properties of addition and subtraction with whole numbers; and connect members of sequential patterns with their ordinal position and use tables, graphs, and diagrams to find relationships between successive elements of number and spatial patterns
- Geometry and Measurement—Use linear scales and whole numbers of metric units for length, area, volume and capacity, weight (mass), angle, temperature, and time; find areas of rectangles and volumes of cuboids by applying multiplication; classify plane shapes and prisms by their spatial features; represent objects with drawings and models (nets for rectangular prisms and plans); use a coordinate system or the language of direction and distance to specify locations and describe paths; and describe transformations (reflection, rotation, or translation) that have mapped one object onto another
- Statistics—Gather, sort, and display multivariate categorical and whole-number data and simple time-series data to answer questions; identify patterns and trends in context, within and between data sets; communicate findings using data displays; evaluate the effectiveness of different data displays; and investigate simple situations involving elements of chance by comparing experimental results with expectations from models of all outcomes, acknowledging that samples vary
The following summary details Level 5 of the English-medium document.l Note that there are no National Standards for mathematics for Year 9 students. The majority of students should have been introduced to or taught each of the following topics or skills by the end of Year 9:
- Number and Algebra—Reason with linear proportions; use prime numbers, common factors and multiples, and powers (including square roots); understand operations on fractions, decimals, percentages, and integers; use rates and ratios; know commonly used fraction, decimal, and percentage conversions; know and apply standard form, significant figures, rounding, and decimal place value; form and solve linear equations; generalize the properties of operations with fractional numbers and integers; and relate tables, graphs, and equations to linear relationships found in number and spatial patterns
- Geometry and Measurement—Select and use appropriate metric units for length, area, volume and capacity, weight (mass), temperature, angle, and time, with awareness that measurements are approximate; convert between metric units using decimals; deduce and use formulas to find perimeters and areas of polygons and volumes of prisms; find perimeters and areas of circles and composite shapes; deduce angle properties of intersecting and parallel lines and angle properties of polygons and apply these properties; create accurate nets for simple polyhedra and connect three-dimensional solids with different two-dimensional representations; construct and describe simple loci; interpret points and lines in coordinate planes, including scales and bearings on maps; define and use transformations and describe the invariant properties of figures and objects under these transformations; and apply trigonometric ratios and the Pythagorean theorem in two dimensions
- Statistics—Determine appropriate variables and measures; consider sources of variation; gather and clean data; use multiple displays, and recategorize data to find patterns, variations, relationships, and trends in multivariate data sets; compare sample distributions visually, using measures of center, spread, and proportion; present a report of findings; evaluate statistical investigations or probability activities undertaken by others, including data collection methods, choice of measures, and validity of findings; compare and describe the variation between theoretical and experimental distributions in situations involving elements of chance; and calculate probabilities, using fractions, percentages, and ratios
- k Experiences with TIMSS 2003, when Māori-medium schools were included, demonstrated that these Year 5 students were unfamiliar with the mathematical and scientific vocabulary. Given that many of these students were learning Māori as their second language, this difficulty with technical words is not surprising.
- l At the Year 9 level, there are too few students in Māori immersion mathematics and science courses to include in TIMSS.
