Programme of Assessment Assignment 1: Numbers and operations


1


Learners use four digit cards to build whole numbers. a largest possible whole number: 9 630 b smallest possible whole number: 3 069 c largest possible odd number: 9 603 d smallest possible even number: 3 096 e first number larger than 5 000: 6 039 f first number smaller than 7 000: 6 930


2


Learners work with the answers in Question 1. a 3 069; 6 039; 9 603 b 9 630; 6 930; 3 096


c 3 069: three thousand and sixty nine d 9 630 = 9 000 + 600 + 30


3


Learners solve some number sentences: a 71 +  = 71;  = 0 b 157 –  = 157;  = 0 c 1 239 – 1 239 =  ;  = 0 d  – 4 813 = 0;  = 4 813


4


Learners solve more difficult number sentences. a  = 53 + 65 + 47 = (53 + 47) + 65 = 100 + 65 = 165 b  = 83 + 54 – 43 = (83 – 43) + 54 = 40 + 54 = 94 c 175 +  = 180 + 10;  = 15 d 597 – 99 = 600 – ;  = 102


5


Learners work with the answers in Question 1. a 9 603 + 6 039 = 15 000 + 600 + 30 + 12 = 15 000 + 600 + 40 + 2 = 15 642


b 6 930 – 3 096 = (6 930 + 70) – 3 096 – 70 = 7 000 – 3 166 = 3 834
