NPV3

FS - ELG Compare quantities up to 10 in different contexts, recognising when one quantity is greater than, less than or the same as the other quantity

1NPV–2 Reason about the location of numbers to 20 within the linear number system, including comparing using < > and =

2NPV–2 Reason about the location of any two-digit number in the linear number system, including identifying the previous and next multiple of 10.

3NPV–3 Reason about the location of any three-digit number in the linear number system, including identifying the previous and next multiple of 100 and 10.

4NPV–3 Reason about the location of any four-digit number in the linear number system, including identifying the previous and next multiple of 1,000 and 100, and rounding to the nearest of each.

5NPV–3 Reason about the location of any number with up to 2 decimals places in the linear number system, including identifying the previous and next multiple of 1 and 0.1 and rounding to the nearest of each.

6NPV–3 Reason about the location of any number up to 10 million, including decimal fractions, in the linear number system, and round numbers, as appropriate, including in contexts.

KS3

• Appreciate the infinite nature of the sets of integers, real and rational numbers.

• Order positive and negative integers, use the number line as a model for ordering of the real numbers; use the symbols =, ≠, <, >, ≤, ≥

• Round numbers and measures to an appropriate degree of accuracy (for example, to a number of decimal places or significant figures).

• Use approximation through rounding to estimate answers and calculate resulting errors expressed using inequality notation a < x ≤ b

• Use a calculator and other technology to calculate results accurately and then interpret them appropriately
