Maths Year 6 Spring Data

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

Conversion: metric/imperial units; line graphs (suggested as 4 days)

Planning and Activities

Day 1 Teaching
Show a 1kg weight. Write some weights in g and kg on cards. Put up a washing line, and order the weights along it. Repeat for capacities in ml/litres.
Group Activities
-- Play a game converting from grams to kilograms and vice versa (1 or 3 decimal places).
-- Convert from litres to millilitres and vice versa, including amounts with 2 decimal places.

Day 2 Teaching
Ask children to write some km distances as metres. Discuss km and miles. Say that 5 miles is about 8km. Find 10, 15, 50 miles in km. Show how to draw a line graph to show this relationship.
Group Activities
-- Plot a line graph with given axes; use this to find kilometre to mile equivalents and vice versa, including at intermediate points on the graph.

Day 3 Teaching
Discuss Imperial measures. Discuss some approximate conversions between pounds, ounces, kg, cm, inches etc.
Group Activities
-- Make connections between regularly-used imperial units and familiar objects and contexts. Relate to well-known metric equivalents, understanding that some of these are approximate.

Day 4 Teaching
Show a table of conversions from grams to ounces. Convert some weights from ounces to pounds and ounces. Draw two axes and label them kilograms and ounces. Then draw the conversion graph and discuss.
Group Activities
Use the in-depth problem-solving investigation ‘Weights in a line’ as today’s group activity.
Or, use these activities:
-- Draw a line graph to convert litres to pints and vice versa.
-- Draw a line graph to convert centimetres to inches.

Mental/Oral Maths Starters

Day 1
Multiply and divide by 10, 100 and 1000 (pre-requisite skills)

Suggested for Day 2
Reading scales (weight) (simmering skills)

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

Suggested for Day 4
Reading scales (general) (simmering skills)


Day 1
Convert from litres to millilitres to order capacities 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 and centimetres to order children in terms of height.

Day 4
Draw a line graph to convert litres to pints and vice versa.
Draw a line graph to convert hand measurements in cm to inches.

Mastery: Reasoning and Problem-Solving

  • Write a familiar object that weighs about:
    (a) 5 Kg
    (b) 1 pound
    (c) 100g
  • Write a familiar container that holds about:
    (a) 1 pint
    (b) 5 ml
    (c) 2 gallons
  • True or false?
    10 lots of 100 grams are 10 kilograms.
    One tenth of a litre is 10ml.
    Half a pint is about 1/4 of a litre.
    You can weigh people in stones.
  • Use this fact: 5 miles = 8km
    15 miles is ? km
    ? miles is 4 km
    64 km is ? miles
    Roughly how many miles is 250 km?

In-depth Investigation: Weights in a Line
Children use systematic working to calculate the number of possibilities of making weights using just two set weights; then look for patterns using line graphs.
