Meas (i) (ii) (iii)
Data (i)

Hamilton Objectives
40. Use, read and write, and convert between, standard units including miles and kilometres, using decimal numbers with up to three places as appropriate.
41. Solve problems using standard units and convert between them.
47. Interpret and construct line graphs and use these to solve problems.

### 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:

### 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.
