#### NUMBER:F

1. Order positive and negative integers, decimals and fractions;

e.g order from smallest: 45%, 0.5, 5/9, −0.6

Use the symbols =, ≠, <, >, ≥, ≤

2. Apply the four operations (+, –, ×, ÷), including formal written methods, to integers, decimals and simple fractions (proper and improper), and mixed numbers –both positive and negative;

Understand and use place value (e.g. when working with very large or very small numbers, and when calculating with decimals.

Divide a decimal by a whole number, including negative decimals, without a calculator. e.g. 0.24 ÷ 6

Divide a decimal by a decimal: 0.3 ÷ 0.6 without a calculator,

3. Recognise and use relationships between operations, including inverse operations (e.g. cancellation to simplify calculations and expressions; use conventional notation for priority of operations, including brackets, powers, roots and reciprocals (BIDMAS)

e.g. 223 – 98 = 223 + 2 – 100 = 125
25 × 12 = 50 × 6 = 100 × 3 = 300

4. Use the concepts and vocabulary of prime numbers, factors (divisors), multiples, common factors, common multiples, highest common factor, lowest common multiple, prime factorisation, including using product (e.g. 2×2×3) notation

Express a whole number as a product of its prime factors.
e.g. 24 = 2 × 2 × 2 × 3
Understand that every number can be expressed as a product of prime factors in only one way.

Find the HCF and LCM of two whole numbers from their prime factorisations

What are the factors of 20?

5. Apply systematic listing strategies

e.g. How many ways can we make 50 pence from a 2p, 5p, and 10p coins

6. Use positive integer powers and associated real roots (square, cube and higher), recognise powers of 2, 3, 4, 5;

e.g. 600 = 2³ × 3 × 5² is worked out from a Prime factor tree.

7. Calculate with roots, and with integer indices

e.g. 24=16 ; √9 = 3; 38 = 2

Recognise simple powers of 2, 3, 4 and 5. e.g. 27 = 33; 2–3 = 1/8

Law of indices:
am × am = a m+n ; am ÷ an = am–n
(am)n = amn

8. Calculate exactly with fractions, surds and multiples of π

Add, subtract, multiply and divide simple fractions (proper and improper), including mixed numbers and negative fractions.

e.g. 11/2 + 3/4; 5/6 × 3/10; –3 × 4/5

2/5 + 5/6; 2/3 + 1/2 × 3/5

9. Calculate with and interpret standard form A × 10n where 1 ≤ A < 10, and n is an integer
1234 = 1.234 × 103
0.000123 = 1.23 × 10–4

Add, subtract, multiply and divide numbers in standard form, without a calculator.

What are the factors of 20?

10. Work interchangeably with terminating decimals and their corresponding fractions
(such as 3.5 and 7/2 or 0.375 or ⅜);

Use division to convert a simple fraction to a decimal. e.g. 1/6 = 0.16666..

11. Identify and work with fractions in ratio problems

Interpret a ratio of two parts as a fraction of a whole.
e.g. £9 split in the ratio 2 : 1 gives parts ⅔ × £9 and ⅓× £9

12. Interpret fractions and percentages as operators

Calculate a fraction of a quantity.
e.g. 2/5 of £3.50
Express one quantity as a fraction of another. e.g. 50p is 2/5 of £2.00

Add 10% to £2.50 by either finding 10% and adding, or by multiplying by 1.1 or 110/100
Calculate original price of an item costing £10 after a 50% discount.

13. Use standard units of mass, length, time, money and other measures (including standard compound measures) using decimal quantities where appropriate

14. Estimate answers; check calculations using approximation and estimation, including answers obtained using technology

Use the symbol ≈ appropriately

15. Round numbers and measures to an appropriate degree of accuracy (e.g. to a specified number of decimal places or significant figures);

Use inequality notation to specify simple error intervals due to truncation or rounding

e.g. If x = 2.1 rounded to 1 dp, then 2.05 ≤ x < 2.15.
If x = 2.1 truncated to 1 dp, then 2.1 ≤ x < 2.2.

16. Apply and interpret limits of accuracy
