Maths – Embedding mastery through Power Maths

Number: Decimals

  • Identify the value of each digit in numbers given to three decimal places and multiply numbers by 10, 100 and 1000 giving answers up to 3 decimal places (dp).
  • Multiply one digit numbers with up to 2dp by whole numbers.
  • Use written division methods in cases where the answer has up to two decimal places.
  • Solve problems which require answers to be rounded to specified degrees of accuracy.

Number: Percentages

  • Solve problems involving the calculation of percentages [for example, of measures such as 15% of 360] and the use of percentages for comparison.
  • Recall and use equivalences between simple FDP including in different contexts.


  • Solve problems involving the calculation and conversion of units of measure, using decimal notation up to three decimal places where appropriate.
  • Use, read, write and convert between standard units, converting measurements of length, mass, volume and time from a smaller unit of measure to a larger unit, and vice versa, using decimal notation to up to 3dp.
  • Convert between miles and kilometres.
  • Recognise that shapes with the same areas can have different perimeters and vice versa.
  • Recognise when it is possible to use formulae for area and volume of shapes.
  • Calculate the area of parallelograms and triangles.
  • Calculate, estimate and compare volume of cubes and cuboids using standard units, including cm3, m3 and extending to other units (mm3, km3).

Number: Algebra

  • Use simple formulae.
  • Generate and describe linear number sequences.
  • Express missing number problems algebraically.
  • Find pairs of numbers that satisfy an equation with two unknowns.

Number: Ratio

  • Solve problems involving the relative sizes of two quantities where missing values can be found by using integer multiplication and division facts.
  • Solve problems involving similar shapes where the scale factor is known or can be found.
  • Solve problems involving unequal sharing and grouping using knowledge of fractions and multiples.
