Numeracy

Numeracy
- Order of operations
  Select and carry out calculations in the correct order of precedence using the ‘rules’ of BODMAS (Brackets then Of then Division then Multiplication then Addition and Subtraction).
- Multiplication
  Calculations involving multiplication of whole numbers.
- Division
  Dividing a single digit whole number where the calculation can go as far as two decimal places.
- Negative numbers
  Negative numbers are mainly used with coordinates and temperature. Use negative numbers in addition and subtraction problems including subtracting a negative number.
- Rounding
  Many calculations result in answers that are more accurate than you need. In such cases the answers are rounded to the required degree of accuracy.
- Rounding and Estimating
  A way of approximating or estimating an answer is to round off using significant figures. You can then select and carry out calculations and round answers to the nearest significant figure.
- Distance, Speed and Time
  Calculations involving distance, speed and time can be worked out using formulae. When doing these calculations, the units used should be consistent.
- Percentages
  Calculations involving percentages of quantities. Working with increases and decreases as well as expressing a quantity as a percentage of another quantity.
- Fractions
  Fractions are calculations involving a fraction of a quantity, shape or object. Equivalent fractions allow cancelling to simplest form.
- Ratio
  A ratio is used to compare two quantities. The quantities should be in the same units.
- Probability
  The link between simple probability and expected frequency is explored. The idea of risk is investigated and its impact on life.
