How does numeracy appear in this context?

 

What might you expect students to do?

From Level 3, learners are increasingly able to use mathematical terms and symbols to describe computations, measurements and characteristics of objects in context. They can use metric units of length, mass and capacity to measure, order and compare objects.

They carry out investigations, collect and organise data into categories and use different methods with and without technology to display the data.

Learners conduct experiments involving chance, describe possible outcomes and recognise variability in results.

By Level 8, students are consolidating their proficiency with the four arithmetic operations, and combinations of these, for general computation involving natural numbers, integers and rational numbers, with and without the use of technology.

They generalise from number to algebra, and expand, factorise, simplify and substitute into simple algebraic expressions, and investigate and use various techniques for collecting data, including random sampling.

The Victorian Numeracy Learning Progressions provide a sequence of key numeracy indicators from Foundation to Level 10 that have been used in the descriptors for each Numeracy Focus.

For specific mathematics content descriptions and achievement standards, see the Victorian Curriculum F-10.

Developing number sense

Quantifying numbers, using additive and multiplicative strategies

Developing number sense includes quantifying numbers, estimating, using additive and multiplicative strategies, as well as:

  • Connecting and ordering number names, numerals and groups of objects using numbers up to the appropriate number of digits for the developmental level
  • Multiplicative thinking: Students can work flexibly with the concepts, strategies and representations of multiplication (and division) as they occur in a wide range of contexts.

Everyday contexts and cross-curricular examples involving quantifying numbers, estimating and additive and multiplicative strategies:

  • Media reports: How many people in a photo, at an event?
  • Science: Investigate wildlife populations, paying special attention to endangered species. Use microscopes to examine very small objects that we can still see
  • Mathematics: Estimate before calculating, then ask whether the answer makes sense
  • Geography: Given a map and the area of one country, estimate the areas of other given countries; Population density – people per a given area
  • Economics: National debt and superannuation savings. For example, see the Australian Debt Clock.

Language to make numeracy focus explicit:

  • Place value and number names, e.g. million, billion, trillion; tenths, hundredths, etc.
  • How much money do we need to save for a mobile phone?
  • “How do you know your answer is sensible?”
  • “How small can something be so that we can still see it?

Events such as New Year bring many people together. A photo can be used to help estimate the number of people at this event

Exploring patterns and relationships

Using number patterns and thinking algebraically

Exploring patterns and relationships includes using number patterns and thinking algebraically, as well as:

  • Identifying and describing pattern rules and relationships that help to identify trends

Everyday contexts and cross-curricular examples involving patterns and relationships:

  • Mathematics: geometric patterns
  • Biology: Nature patterns – e.g., Fibonacci sequences in leaves, pine cones and shell designs
  • Art and design: Noticing tessellations and patterns in wallpaper and fabric design
  • Art (Architecture) and history: Exploring where and why the golden ratio was used in well-known buildings such as the Parthenon
  • Geography: Colouring a map of Africa using the 4-colour theorem (where no more than four colours are required to colour the regions of the map) so that no two adjacent regions have the same colour.

Language to make the numeracy focus explicit:

  • “How could the pattern be expressed using algebra, starting with x for the unknown number?”
  • “What are some ways that we could all find out who uses algebra in their occupations?”
  • “Can you describe the pattern to me?”

Patterns are all around us. These  tiles of the same shape have various patterns. Notice the similarities and the differences between each tile. 

Using proportional reasoning

Using proportional reasoning includes operating and interpreting decimals, fractions, percentages, ratios and rates, as well as:

  • Health and Physical Education: Noting and discussing the percentages of sugar and fat in specific foods that children may enjoy eating. What do “lite, light, and low fat” actually mean in such products?

The use of appropriate language and questions help to make the numeracy focus explicit:

  • Percentage, positive and negative fractions (fraction families, e.g. halves, quarters and eighths or thirds and sixths, including mixed numbers and improper fractions), equivalent, denominator, numerator, ratio, rate, speed, compare, decimal
  • “Which is better value for money, 150g of yoghurt for $1.80, or 350g of yoghurt for $4.25?
  • “How do we know the original price if we know the price including GST?”
  • “Why do cars generally slow down going up a very steep hill?”
  • “When do you hear the word ‘percent’ used, and what is your understanding of its meaning?”
  • “How could you express each of the Australian states’ populations as a percentage of Australia’s population?”
  • “What is the ratio of girls to boys in your class if 3/5 of the class are girls?”

Nutrition panels provide information as a proportion, usually in the form of energy per serve and per 100 grams

Understanding and using geometric properties and spatial reasoning
