Indicator: B5.1.3.1.6 - Recognise data types (integer, double, float).

By the end of the lesson, learners can:

Define data type in their own words and explain why computers need to know the type of data being used.
Identify integers as whole numbers, including negative numbers and zero, and give examples from everyday life.
Distinguish between float and double as number types that include decimal points, with double capable of holding larger and more precise values.
Sort given numbers into the correct data type category (integer, float, double) with accuracy.
Play and complete a group game where they call out numbers and classmates identify the correct data type, building on the exemplar activity from the curriculum.
