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 and 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. Pupil Version -Print this slide and the next slide two to a page and give to pupils to glue into their books. These should be printed onto blue paper so that pupils can easily find them in their books. Pupils should be referring to these every lesson.

a) Round 231 to the nearest 10 Round 431 to the nearest 100 b) Write down 3 multiples of…. 5, 3 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? j) Write 70 as a product of its prime factors. 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.
