Home Learning Support

Here are some ideas to support the learning of mathematics strategies for students in  years 1-8. These may be helpful for you to support your child at home. Most strategies have a learning goal, an example and a video.

Level 1 - Stages 1 - 4      (Generally Years 1 and 2)

Level 2 - Stage 5       (Generally Years 3 and 4)

 Addition and Subtraction I am able to use known basic facts to solve addition and subtraction problems.I am able to use doubles. Example: 8 + 7 is 8 + 8 - 1 Using Doubles to solve additionI am able to solve multi-digit problems using partitioning. Example: 43 + 25 = (40 + 20) + (3 + 5) = 60 + 8 = 68Partitioning with AdditionI am able to use rounding and compensating. Example: 39 + 26 = 40 + 25 = 65Rounding and Compensating with AdditionI am able to solve subtraction problems by partitioning the second number. Example: 84 - 8 is 84 - 4 - 4 = 76 Multiplication and Division I am able to solve multiplication and division problems by using repeated addition. Example 1: 4 x 6 as (6 + 6) + (6 + 6) = 12 + 12 = 24Example 2: 20 ➗ 4 = 5 because 5 + 5 = 10 and 10 + 10 = 20.Repeated Addition for Multiplication Fractions I am able to find a fraction of a number.Example: ⅓ of 12 = 4 because 4 + 4 + 4 = 12Find a fraction of a set

Level 3 - Stage 6       (Generally Years 5 and 6)

 Addition and Subtraction I am able to use a range of the following strategies to solve problems;I am able to use rounding and compensating Example: 63 - 39 = 63 - 40 + 1 = 24Compensating and Rounding AdditionCompensating and Rounding SubtractionI am able to use reversibility (number line)Example: 63 - 39 = 39 + ▢ = 63Reversibility and CompensatingNumber LineI am able to use place value partitioningExample: 156 - 38 = (156 - 30 = 126) 126 - 8 = 118Addition PartitioningSubtraction Partitioning Multiplication and Division I am able to use doubling and halvingExample: 4 x 8 = 2 x 16 - 32Doubling and HalvingI am able to solve unknown facts from facts I knowExample: 9 x 6 is (10 x 6) - 6 = 54I am able to reverse division problems into multiplication problemsExample: 63 ➗ 7 = 9 because 9 x 7 = 63 (reversibility) Fractions I am able to find a fraction of a set by using multiplication or division facts.Example: ⅓ of 36 = 12 because 36 ➗ 3 = 12, or 3 x 12 = 36Finding Fraction of a setI am able to rename improper fractions11/3 = 3 3/11 because 3 fits into 11 3 times with a remainder of 3.Improper to mixed fractions

Level 4 - Stage 7      (Generally Years 7 and 8)

 Addition and Subtraction I am able to solve addition and subtraction problems with decimals up to 2 decimal places using; I am able to solve problems for integersIntegers Video Multiplication and Division I am able to multiply 2 digit by 1 digit numbers Box method for 2 digit by 1 digitI am able to multiply 2 digit by 2 digit numbersBox method for 2 digit by 2 digit I am able to solve division problems using; Fractions I am able to find equivalent fractionsEquivalent FractionsI am able to find the decimals and percentages of a fractionDecimals, Fractions and Percentages I am able to find fractions of a setFind fractions of a setI am able to solve simple ratio problemsFinding a WholeFinding a whole

Level 4 / 5 - Stage 8:       (Generally Years 8 and 9)

 Addition and Subtraction I am able to add and subtract fractionsAdding FractionsI am able to solve addition and subtraction problems with decimals up to 3 decimal places. Multiplication and Division I am able to multiply fractionsMultiplying and dividing fractions - DivisionMultiplying and dividing fractions - MultiplicationI am able to multiply and divide decimalsMultiplying DecimalsConversion https://www.youtube.com/watch?v=elXQE-5OB78 Fractions I am able to find a percentage of a numberI am able to solve fractional ratios
