Expected level of development
Australian Curriculum Mathematics V9: AC9M3A02, AC9M3A03
Numeracy Progression: Number patterns and algebraic thinking: P3, Additive strategies: P8, Multiplicative strategies: P5
At this level, students extend and apply knowledge of number facts to 20 for addition and subtraction, and extend to larger numbers. They demonstrate proficiency with multiplication facts for 3, 4, 5 and 10 and further develop their knowledge of related division facts.
Provide opportunities for students to develop proficiency in automatic recall of the number facts associated with a mathematical operation. Use models such as fact family triangles to record number facts for inverse operations (addition and subtraction, and multiplication and division). Use maths games that draw on additive or multiplicative thinking and use of number facts, including strategy games to reach a target number.
Explore number patterns using a hundreds chart. Students identify patterns, skip counting by 3, 4, 5 and 10. Model and explore arrays using materials such as counters or Unifix cubes to record representations.
Use calculators to explore patterns in repeated addition and subtraction. Make connections between multiplication and repeated addition, and between division and repeated subtraction. Use number lines to reinforce the connections and to explore patterns.
Teaching and learning summary:
 Describe a rule for a number pattern, then create the pattern.
 Partition using materials and partpartwhole diagrams to develop subtraction facts related to addition facts.
 Understand basic addition and related subtraction facts and use extensions to these facts.
 Use concrete or virtual manipulatives, groups and repeated addition to recognise patterns and establish the 3, 4, 5 and 10 multiplication facts.
 Use a calculator or spreadsheet to generate a list of the multiples of five to develop the multiplication and related division facts for five.
Students:
 use skip counting to continue number patterns
 recall addition and subtraction facts up to 20
 recall multiplication facts for 3, 4, 5 and 10 and their related division facts.
Some students may:
 have difficulty with basic number facts
 have limited strategies and revert to counting on fingers or similar inefficient strategies.
Provide a range of strategies through Number talks and help students make connections between addition and subtraction and between multiplication and division using materials and relevant models.
Use arrays to develop number facts. Start with a limited number of facts learned grouped according to counting patterns of twos, fours, threes, fives and tens. Then progress, adding the next grouping of facts, when students demonstrate proficiency.

The Learning from home activities are designed to be used flexibly by teachers, parents and carers, as well as the students themselves. They can be used in a number of ways including to consolidate and extend learning done at school or for home schooling.
Learning intention
 We are learning to improve our recall of number facts.
Why are we learning about this?
 Having efficient strategies helps us work out more difficult maths problems.
What to do
1. Here is a problem: 9 x 13
 Which of these number facts could you use to help solve the problem?
 How can that number fact help you?
1 x 11  12 x 12  10 x 11  10 x 13 
2 x 10  13 x 13  11 x 11  11 x 12 
13 x 2  11 x 2  10 x 10  1 x 13 
4 x 13  9 x 10  1 x 3  14 x 11 
2. The fact families for 24 are:
4 x 6 = 24, 6 x 4 = 24, 24 ÷ 6 = 4, 24 ÷ 4 = 6
3. Can you think of other number facts for 24? Write as many as you can.
4. Write the fact families for 18 and for 30.
Success criteria
I can:
 recall basic number facts
 write fact families for twodigit numbers.

Teaching strategies
A collection of evidencebased teaching strategies applicable to this topic. Note we have not included an exhaustive list and acknowledge that some strategies such as differentiation apply to all topics. The selected teaching strategies are suggested as particularly relevant, however you may decide to include other strategies as well.

Structuring lessons
A welldeveloped lesson structure is important for both teacher and students.
Go to resource 
Explicit teaching
Explicit teaching is about making the learning intentions and success criteria clear, with the teacher using examples and working though problems, setting relevant learning tasks and checking student understanding and providing feedback.
Go to resource 
Multiple exposures
Providing students with multiple opportunities within different contexts to practise skills and apply concepts allows them to consolidate and deepen their understanding.
Go to resource 
Spaced, interleaved and retrieval practice
These are three strategies that can be used to increase student retention and recall of their learning.

Teaching resources
A range of resources to support you to build your student's understanding of these concepts, their skills and procedures. The resources incorporate a variety of teaching strategies.

Arrays
Use this interactive tool for students to practise recall and recognising patterns in multiplication facts.
Go to resource 
reSolve: Algebra – Number sequences
Students are challenged to solve problems to generate patterns, explore strategies for addition and subtraction and apply their skills to constructing their own new patterns.
Go to resource 
Musical number patterns: musical times
Students make some music by building up rhythms from four instruments, and make a counting rule that matches a pattern on a number line.
Go to resource 
Times tables shifts
This interactive task will help students become familiar with multiplication (times tables) facts, by encouraging them to think about number properties.
Go to resource 
Circus towers: square stacks
Students work out how many acrobats are needed to form squareshaped human towers and describe how the number pattern is formed.
Go to resource 
Gecko feet
Students link the development of skipcounting patterns to bars on a relationship graph and then plot the skipcounting patterns on a hundreds board.

Supermarket displays
In this unit, students explore the number patterns created when tins are stacked in different arrangements and keep track of the numbers involved by drawing up a table of values.

What was in the box?
This problem is rather like a function machine, but it can be more interesting and is easily extended to challenge a wide range of pupils.
