Assessment
Learning outcomes(LOs) |
LO 1 |
Numbers, Operations and RelationshipsThe learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems. |
Assessment standards(ASs) |
We know this when the learner : |
1.1 describes and illustrates the historical and cultural development of numbers; |
1.2 recognises, classifies and represents the following numbers in order to describe and compare them:1.2.3 numbers written in exponent form; including squares and cubes of natural numbers and their square roots and cube roots;1.2.6 multiples and factors;1.2.7 irrational numbers in the context of measurement (e.g. square and cube roots on non-perfect squares and cubes); |

Two factors: 1 and itself
{4, 6, 8, 9, . . . }
More than 2 factors
- Own choice: Ends on even numbers
- Sum of all the numbers ÷ 3
- Last numbers ÷ 4: e.g. 84 ÷ 4 = 21
- Ends on 0 / 5
- Divisible by 2 and 3
- Last 3 numbers ÷ 8: e.g. 3 720 ÷ 8 = 90
- Add all the numbers ÷ 9
- Ends on 0
- e.g. 2 6 8 2 + 8 = 10, 10 – 10 = 0
0 ÷ 11 = 0, 4 + 6 = 10

- Count on, e.g. in 3’s: Number ÷ 3
- Number that can divide into another number
- Number with 2 factors: 1 and itself
- Prime number that can divide into another number
- Even: (Ends on even numbers) [divisible by 2]
Uneven: (Not divisible by 2)
