- 1Partitive/Sharing Division DefinitionYou know the number of groups and you are trying to find the amount inside each group. Number of shares are known.
- 2Partitive/Sharing Division Example20 biscuits altogether. They are equally shared between 5 dogs, how many biscuits does each dog get?
20/5 = 4 biscuits each. - 3Quotative/Measuring Division DefinitionYou know the amount in each group, you are trying to find out how many groups there are. Size of the share is known.
- 4Quotative/Measuring Division Example20 biscuits altogether. Each dog gets an equal amount of 4 biscuits each. How many dogs get a share of the biscuits?
20/4 = 5 dogs. - 5Multiplication/Division PropertiesCommutative
Associative
Distributive
Inverse/Reversibility - 6Commutative DefinitionChange the order of factors.
- 7Associative DefinitionDoubling, halving, thirding and trebling.
Division: Factorising
Multiplication: Proportional adjustment - 8Distributive DefinitionSplitting factors and using tidy numbers.
Division: Chunking
Multiplication: Place value partitioning
Both: Rounding and compensating - 9Inverse DefinitionDoing and undoing.
Reversing. - 10Counting All (CA) FeaturesCounting using units of one.
Multiplication: forming sets and counting objects by one
Division: Sharing objects one by one or forming sets and counting by one. - 11Advanced Counting (AC) - Early Additive (EA) Stage 4 - Stage 5Composite counting.
Multiplication: skip counting or repeated addition.
Division: sharing or subtraction by skip counting. - 12Advanced Additive (AA) Stage 6Known facts and deriving.
Multiplication: knowing facts and using commutative, associative and distributive properties to find unknown facts.
Division: sharing, repeated subtraction through reverse multiplication (inverse). - 13Problem TypesEqual groups
Rate
Comparison
Part-Whole
Cartesian Product
Rectangular area - 14Equal GroupsSharing and forming of equal groups.
- 15RateUse of measurable units such as time.
- 16ComparisonComparing a quantity to find another.
- 17Part-WholeUses more than one method to find whole answer e.g ratio andmultiplication
- 18Cartesian ProductCombinations made from two different quantities
- 19Rectangular AreaTwo factors combined to make a product. Changing the order of factors doesn't change the product.
- 20FactorisationDivision proportional adjustment:
136/8 = 136/2/2/2 = 68/2 = 34/2 = 17 - 21Number KnowledgeDivision:
130/5 = 130/10 x2 = 13x2 = 26 - 22ChunkingDivision place value partitioning:
136/8 = 80/8 + 56/8 = 10+7 = 17 - 23Rounding and Compensating DivisionDivision:
136/8 = 160/8 -24/8 = 20-3 = 17 - 24Place Value PartioningMultiplication:
38x5 = 30x5 +8x5 = 150+40 = 190 - 25Proportional AdjustmentMultiplication:
38x5 = 19x10 = 190 - 26Rounding and CompensatingMultiplication:
38x5 = 40x5 - 2x5 = 200-10 = 190 - 27Division isThe inverse of multiplication and repeated subtraction.
- 28Multiplication isThe inverse of division and repeated addition.
- 29Place value partitioning extra examples3x37= 3x30 + 3x7
5x42= 5x40 + 5x2
4x29= 4x20 + 4x9 - 30Rounding and Compensating extra examples6x24= 6x25 - 6x1
3x29= 3x30 - 3x1
