March 11, 2023

Scheme of work: GCSE Foundation: Year 9: Term 3: Units of Measure

Prerequisite Knowledge

Multiply and divide whole numbers and those involving decimals by 10, 100 and 1000
measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml)
tell and write the time from an analogue clock, including using Roman numerals from I to XII, and 12-hour and 24-hour clocks

Success Criteria

Use standard units of measure and related concepts (length, area, volume/capacity, mass, time, money, etc.)
measure line segments and angles in geometric figures, including interpreting maps and scale drawings

Key Concepts

Understanding and applying the keywords is vital throughout this topic.
Metric terms such as milli, cent, kilo need to be associated with their numerical equivalences.
Relate metric conversions to multiplying and dividing by 10, 100 and 1000.
Practical measuring activities using the appropriate equipment helps students to remember the imperial/metric conversions.

Common Misconceptions

Students sometimes fail to recognise that imperial and metric units are two distinct sets of measurements.
Remembering the metric/imperial conversions often prove difficult for most students.
Students may have difficulty with the numerical conversions, especially with imperial units. Encourage the use of calculators when appropriate.
