Number and the number system

Y3Y4Y5 and 6
Pupils represent and explain the base ten structure of the number system (up to thousands) in different contexts.Pupils represent and explain how the multiplicative nature of the number system includes whole numbers beyond thousands and decimal numbers (up to two decimal places) in different contexts.Pupils represent and explain how the multiplicative nature of the number system includes whole numbers up to 10 million and decimal numbers beyond hundredths, in different contexts. They use this understanding to convert between different units of measures, explaining and justifying their decisions.
Pupils place and identify numbers (up to one thousand) on a number line (linear number system including scales in measures and statistics) using their understanding of
· how close the numbers are to previous and next multiples of 10 and 100 boundaries,
· dividing 100 and 1000 into 2, 4, 5 and 10 equal parts
explaining and justifying their decisions.
Pupils place and identify whole and decimal numbers on a number line (linear number system including scales in measures and statistics) using their understanding of
· how close the numbers are to previous and next multiples of 10/100/1000 boundaries,
· dividing 100, 1000 and 10 000 into 2, 4, 5 and 10 equal parts
explaining and justifying their decisions and using this understanding to round numbers.
Pupils place and identify whole numbers up to 10 million and decimal numbers (beyond hundredths) on a number line (including scales in measures and statistics) using their understanding of
· how close the numbers are to
· dividing 1 into 2, 4, 5 and 10 equal parts
· negative numbers
explaining and justifying their decisions and using this understanding to round numbers.
