In this Year 6 Round Any Integer lesson, children round any whole number to a required degree of accuracy.
The Year 6 Round Any Integer PowerPoint guides both teachers and children through the lesson, including use of the varied fluency, reasoning and problem solving, deeper reasoning and scaffolded resources. Key learning information about this step:
Key Vocabulary
integers: Whole numbers, which can be positive, negative or zero.
rounding: When a number is replaced with an approximated value. Numbers are often rounded to the nearest 10, 100 or 1,000. Decimal numbers may also be rounded to the nearest whole number.
multiple: A product of one number multiplied by another number. For example: multiples of 10 are the products of numbers multiplied by 10.
midpoint: The point on a number line that is exactly halfway between the start and end values.
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
