'Guess My Number Game' was developed to consolidate knowledge of numbers to 100. Students are able to use their knowledge of mental counting strategies to help navigate this game.
Quantify sets of objects, to at least 120, by partitioning collections into equal groups using number knowledge and skip counting
Partition one- and two-digit numbers in different ways using physical and virtual materials, including partitioning two-digit numbers into tens and ones
Add and subtract numbers within 20, using physical and virtual materials, part-part-whole knowledge to 10 and a variety of calculation strategies
Use mathematical modelling to solve practical problems involving additive situations, including simple money transactions; represent the situations with diagrams, physical and virtual materials, and use calculation strategies to solve the problem
Recall and demonstrate proficiency with addition facts to 20; extend and apply facts to develop related subtraction facts
Recall and demonstrate proficiency with multiplication facts for twos; extend and apply facts to develop the related division facts using doubling and halving
Count collections to 100 by partitioning numbers using place value
Develop confidence with number sequences to and from 100 by ones from any starting point. Skip count by twos, fives and tens starting from zero
Represent and solve simple addition and subtraction problems using a range of strategies including counting on, partitioning and rearranging parts
Investigate number sequences, initially those increasing and decreasing by twos, threes, fives and tens from any starting point, then moving to other sequences
Uses a range of strategies and informal recording methods for addition and subtraction involving one- and two-digit numbers
Describes mathematical situations and methods using everyday and some mathematical language, actions, materials, diagrams and symbols
Uses objects, diagrams and technology to explore mathematical problems
Supports conclusions by explaining or demonstrating how answers were obtained
Applies place value, informally, to count, order, read and represent two- and three-digit numbers
Uses a range of mental strategies and concrete materials for multiplication and division
Uses the structure of equal groups to solve multiplication problems, and shares or groups to solve division problems
Uses number bonds and the relationship between addition and subtraction to solve problems involving partitioning
Reasons about representations of whole numbers to 1000, partitioning numbers to use and record quantity values
Develop confidence with number sequences to and from 100 by ones from any starting point. Skip count by twos, fives and tens starting from zero

Solve simple addition and subtraction problems using a range of efficient mental and written strategies
Investigate number sequences, initially those increasing and decreasing by twos, threes, fives and ten from any starting point, then moving to other sequences
Recognise and represent multiplication as repeated addition, groups and arrays
Apply repetition in arithmetic operations, including multiplication as repeated addition and division as repeated subtraction
Recognise and represent division as grouping into equal sets and solve simple problems using these representations
