Maths Year 5 Autumn Measures and Data

Each unit has everything you need to teach a set of related skills and concepts.

Understand metric and imperial units (suggested as 3 days)

Planning and Activities

Day 1 Teaching
Show a kg weight. How else can we write 1kg? Remind children that ‘kilo’ means 1000. Hang a 0 card at 1 end of a washing line and 1000g with 1kg pegged beneath it at the other. Children peg different nos. of grams along the line. Repeat for litres and ml.
Group Activities
-- Play a game converting from grams to kilograms and vice versa (1 decimal place).
-- Fill in missing amounts on a 0–1kg line. Order containers by eye, then convert from litres to millilitres and vice versa, to check.

Day 2 Teaching
Write a variety of distances on the board and use these to convert between metres and kilometres. Start to convert between miles and km and begin to draw line graph for conversion and read intermediate points.
Group Activities
Use the in-depth problem-solving investigation ‘Inches and Barleycorns’ from NRICH as today’s group activity.
Or, use these activities:
-- Construct a line graph to convert from miles to km and vice versa.

Day 3 Teaching
Brainstorm imperial units other than miles, e.g. pints, pounds, stones, ounces, feet, inches, yards. Do children know the contexts where they are used? Using different familiar contexts (packet of crisps, baby’s weight, milk, etc.) explore equivalent SI units.
Group Activities
-- Use known facts to convert between centimetres and inches, kilograms and stones/pounds, litres and pints.
-- Measure height in cm, convert to inches, draw line graph to check. Work out how many grams are in a pound, use scales to check.

You Will Need

Mental/Oral Maths Starters

Day 1
Reading scales (weight) (pre-requisite skills)

Day 2
Multiply and divide by 10 and 100 (pre-requisite skills)

Suggested for Day 3
Reading scales (capacity) (simmering skills)


Day 1
Convert from litres to millilitres so as to put a range of capacities in order.

Day 2
Use a line graph to convert from miles to km and vice versa.

Day 3
Use conversions between feet and inches to metres to complete a ‘ready reckoner’ to help people to approximately convert their heights from feet and inches to metres and centimetres, or vice versa.

Mastery: Reasoning and Problem-Solving

  • True or false?
    1050g = 1.5Kg.
    1 pint is about 1.5 litres.
    4 ounces is a bit more than 100g.
    2.5 inches = 1 cm.
    1 metre is a bit bigger than a yard.
  • If we assume 3 miles = 5 kilometres, write the missing numbers.
    ☐ km = 30 miles.
    35km =☐ miles.
    ☐ miles = 2.5km.
  • What imperial unit would be used to measure…
    The length of a large dog, nose to tail?
    The weight of a child’s lunch box?
    The capacity of a baby bath?
