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.
a) Round 231 to the nearest 10 Round 431 to the nearest 100 b) Write down 3 multiples of…. 5, 3 j) Write 70 as a product of its prime factors. c) 20, 100, 2, 5, 10, 4 Which of these numbers are factors of 10 ? How do you know? d) What is 42 e) What is the square root of 36? f) Round 2. 3456 to 2 decimal places g) What is the Highest Common Factor of 15 & 20 h) What is the lowest common multiple of 15 and 20? i) Write down a prime number between 10 and 20. How do you know that it is a prime number? k) Explain how you can use prime factors to find the Lowest Common Multiple and Highest Common Factor of two numbers. Use an example to explain.
