Teaching Percentages
Percentages are part of a greater ‘connected’ set of topics, extending the knowledge of proportions pupils gain from working with fractions and decimals.
What are percentages?
A percentage is a proportion of a whole number, expressed as a value out of a hundred.
What does the percentage mean?
Percentage means ‘out of one hundred’.
When teaching a new concept, particularly one with unfamiliar vocabulary, I have always found it easier to start the unit by breaking down the word into something far more familiar to them.
The models and mathematical imagery we use when teaching percentages should mirror those we use for fractions.
Because students should have looked at the relationship between fractions and decimals before percentages, they should already have some mental models to apply to this unit of work.
