Year 7 Number line Types of Number a

Year 7 - Number line Types of Number. a) I can round whole numbers to the nearest 10, 100 or 1000. b) I can find multiples of any numbers up to 12. c) I can identify factors of two digit numbers. I know simple tests for divisibility for 2, 3, 4, 5, 6, 8, 9 I can find all the factors of number by checking for divisibility. d) I can square and cube numbers. e) I can square root a number. f) I can round numbers to a given number of decimal places or significant figures. g-i) I can use the concepts and vocabulary of prime numbers, highest common factor, lowest common multiple. I understand can use powers (square, cube and higher). I understand that not all numbers will have an exact square root. j) I can express a number as a product of its prime factors. k) I can use prime factor decomposition to find LCM and HCF.
