Selecting and Using Appropriate Numerical Notation and Units
Understanding Numerical Notation
-
Numerical Notation involves the way numbers are written and understood.
-
It's important to be able to read and write numbers in whole number form, decimal form, and fractions.
-
Required to understand scientific notation, especially when dealing with very large or small values.
-
Recognise the difference between positive and negative numbers in context.
-
Understand ordinal numbers (1st, 2nd, 3rd, etc.) and their use in different contexts.
Utilizing Appropriate Units
-
All numerical values should be presented with appropriate units, unless they are dimensionless.
-
Familiarise yourself with common units such as kilograms for mass, metres for length, and seconds for time.
-
Need to understand metric prefixes such as kilo-, centi-, and milli-.
-
Conversion between different units within the same system, e.g. centimetres to metres, is crucial.
-
Learn to convert between imperial and metric units for some values like length (miles to kilometers) and weight (pounds to kilograms).
-
Understand time conversions, including seconds to minutes, minutes to hours, and hours to days.
Practical Application of Numerical Notation and Units
-
Accurately use appropriate numerical notation and units in problem-solving situations.
-
Consider the appropriate level of accuracy or estimation based on the context of the problem.
-
Recognise when conversion between units is required in a problem.
-
Determine the appropriate scale for reading diagrams, maps or similar representation.
-
Check final answers to ensure they are in the correct format and feature the correct units.
