Year 6 Term 3

Key Concepts – Number – Fractions, decimals and percentages

  • Children fully understand the relationship between fractions, decimals and percentages.
  • Children understand common factors and multiples and can use them to simplify fractions.
  • Children can compare and order fractions including placing them on a number line.
  • Children can multiply pairs of fractions.
  • Children can divide fractions by whole numbers.
  • Children recognise simple decimal and fraction equivalents and can find them by relating fractions to division.
  • Children can round to a given degree of accuracy.
  • Children can identify the value of each digit in a number up to 3d.p.

Key Vocabulary

Proper/improper fraction

Equivalent fraction

Mixed Number

Decimal equivalent

 In every/for every


Per cent %

Key Concepts –Topic- Area and perimeter, measures and geometry

  • Children know that shapes with the same area can have different perimeters and vice versa.
  • Recognise when it is possible to use formulae to find area.
  • Know the formula to calculate area of parallelograms and triangles.
  • Can plot coordinates in all 4 quadrants.
  • Children can draw and translate shapes on a grid following instructions given.
  • That perimeter is used with 2D shapes
  • That perimeter can be calculated by adding the length of all of the sides of a shape together.
  • That perimeter allows you to calculate the total distance around the edge of a shape. Circumference is used for circular shapes.
  • That children understand the value of mm, cm and m and how to convert between these measurements
  • Not all diagrams are drawn to scale and as such rulers cannot always be used.
  • The length of a missing side can be calculated with knowledge of the opposite side(s)

Key Vocabulary

square metre (m 2)

square millimetre (mm 2)

Common Misconceptions – Fractions, decimals and percentages

Multiplying fractions leads to a smaller fraction as a result.

Dividing a fraction leads to a larger result.

Children confuse the numerator and denominator when comparing and ordering fractions.

Common Misconception – Area and perimeter, measures and geometry

That children will confuse area and perimeter.

When a shape has a missing measurement, the children will just ignore the side.

Children will use rulers in questions which are not drawn to scale leading to anomalous answers.

Children will not ensure that all measurements are in the same unit or incorrectly convert them.
