23 Compound Measure Conversion between units learning objectives

23. Compound Measure

Conversion between units learning objectives: convert between units of measure in the same system (conversion between imperial units will be given. Metric equivalents should be known) (7. 1) • know rough metric equivalents of pounds, feet, miles, pints and gallons (7. 1) • convert between imperial and metric measures (7. 1) Reference Material • 10 Ticks: MEP:

Speed, distance, time learning objectives: • • calculate speed (7. 3) use the relationship between distance, speed and time to solve problems (7. 2, 7. 3) convert between metric units of speed, eg km/h to m/s (7. 3) construct and interpret distance time graphs (15. 6) Reference Material 10 Ticks: MEP:

Density learning objectives: • • • know that density is found by mass ÷ volume (7. 4) use the relationship between density, mass and volume to solve problems, eg find the mass of an object with a given volume and density (7. 4) convert between metric units of density eg kg/m 3 to g/m 3 (7. 4) Reference Material 10 Ticks: MEP:

Upper and lower bounds learning objectives: • • calculate the upper and lower bounds of calculations, particularly when working with measurements (4. 9, 4. 10) find the upper and lower bounds of calculations involving perimeter, areas and volumes of 2 -D and 3 -D shapes (4. 10) find the upper and lower bounds in real life situations using measurements given to appropriate degrees of accuracy (4. 10) give the final answer to an appropriate degree of accuracy following an analysis of the upper and lower bounds of a calculation (4. 10) Reference Material 10 Ticks: MEP:
