I can divide by one or two digit number, using chunking (with remainders). I can use an efficient written method to multiply and divide positive and negative numbers to solve problems. I can multiply and divide a decimal with one or two decimal places by a whole number. I understand the associative law and how this applies to multiplication questions I can use the order of operations I am familiar with and can use the correct language for different types of numbers 5 2 I recognise that prime numbers have only two factors and can recall prime numbers up to 19 and establish the prime numbers up to 100. I understand and can apply knowledge of decimal notation for tenths, hundredths and thousandths. I can round decimals to the nearest whole number. •     I can round decimals to the nearest one decimal place and two decimal places. I can use the rules of arithmetic and inverse operations in the context of positive integers. •     I can recognise and use cubes and cube roots for positive and negative integers and the notation for cubed, including on a calculator. I can write positive and negatives powers of 10. •     I can work inter-changeably with fractions, decimals and percentages. •     I can recognise where converting between fractions, decimals and percentages can make a calculation easier. I can use division to convert a fraction to a decimal and distinguish between recurring and terminating decimals. 4 1 I can recognise and show families of common equivalent fractions. •     I can compare and order simple fractions •     I can find fractions of simple whole numbers •     I can add and subtract fractions with the same denominator. •     I can multiply proper fractions by whole numbers • I can identify the effect of dividing proper fractions by whole numbers I can complete percentage calculation to find any percentages I can express one quantity as a percentage of another I can divide an amount into a given ratio. I can solve simple problems involving ratio and direct proportion I can simplify a ratio use this to solve problems 3 WT+ I can multiply and divide integers and decimals by 1, 10, 100, 1000, and explain the effect. I can read and write numbers up to four digits and show understanding of place value up to four digits. I can understand and use the concepts of greater than and less than. I can read, write and compare decimal numbers with up to 2.d.p, and apply this to different situations e.g. using pounds and pence, reading temperatures etc. I can show understanding of place value of decimals using notation for tenths and hundredths. I can identify the position of decimal numbers on a number line. I can recognise and interpret negative numbers in contexts such as temperature and money. I can identify positive and negative numbers on a number line and use this to order positive and negative numbers. I understand and can find multiples, factors, factor pairs, proper factors and common factors for most numbers. I can use mental strategies to add and subtract numbers up to two digits You understand how the commutative law applies to addition and subtraction. I can recall and use positive integer complements to 100. I understand how to subtract larger 1 digit positive integers from smaller positive integers producing negative numbers. I can use efficient written methods to add up to 2 digit positive integers and subtract up to 1 or 2 digit positive integers.
