Life after Levels - curriculum content and exemplar material Year 7 Autumn Term Mathematics Autumn 1 – Adding and Subtracting Mastered Secure Developing Emerging I can manipulate standard form when adding and subtracting. I can recognise and understand why standard form is used. I can add and subtract 2 and 3 digit numbers. I can convert between a 12 hour clock and 24 hour clock. I can determine what the important information is from a worded question and use it effectively when solving a problem. I understand the concept of adding and subtracting negative numbers including knowing that 4 - -3 = 4 + 3 = 7. I can manipulate decimals, this includes adding and subtracting decimals with differing amounts of decimal places. I understand which type of rounding to use (significant figures, decimal places) and how it may factor in the accuracy of an answer. I can determine when and why to use approximation and estimation within calculations. I can justify the importance of rounding and why we need to use it in different circumstances. I can use estimation to check answers. I understand how time zones work. I can interpret worded problems by breaking them down into smaller chunks or tasks, and then visually representing them (Bar Modelling). I can use the column method correctly to line up decimals when adding and subtracting. I know and understand that 4 - -3 = 4 + 3 = 7. I understand the concepts of times zones and how they fit around GMT. I can solve worded problems involving time zones and travelling. I understand how timetables are used in the real world, and how they are interpreted to answer worded questions. I understand how to convert time using times zones. I know my number bonds to 10. I can add single digit numbers. I can subtract single digit numbers (where the answer is positive), e.g. 8 – 3 = 5. I know my number bonds to 10. Life after Levels - curriculum content and exemplar material Year 7 Autumn Term Autumn 2 – Multiplication and Division I can multiply and divide effectively using standard form. I can understand the concepts of multiplying and dividing negative numbers, including knowing that -4 x -3 = 12, -4 x 3 = -12 and so on. I can determine what the important information is from a worded question and use it effectively when solving the problem. I can understand how many decimal places are required when multiplying decimals. Be able to multiply decimals such as 21.34 x 0.123. I can understand how to deal with remainders using long or short division. I can carry out long division calculations with a divisor greater than 25 with remainders. I can multiply a 3 digit number by a 2 digit number using either column method or grid method correctly. I can divide with a divisor greater than 10 with remainders. I understand that division and multiplication are inverse operations. I understand what HCF and LCM mean and how to find them. I can define what a prime number is and explain why 1 is not a prime number. I understand the relationship between squaring and square rooting and cubing and cube rooting a number. I can mentally recall all the multiplication tables from 1-12. I can multiply numbers within multiplication tables 1-12. I can multiply a 2 digit number by a 2 digit number. I understand how to multiply and divide whole numbers by 10 and 100. I understand the importance of place value. I understand how to divide using long division or short division with no remainders. I understand what the terms ‘multiples’ and ‘factors’ mean, and give examples of both. I understand how to use BIDMAS within all calculations. I can recall the first 10 square numbers. I can recall the first 5 cube numbers. I understand what the terms ‘halving’ and ‘doubling’ mean. Life after Levels - curriculum content and exemplar material Year 7 Autumn Term Example Questions 1. Calculate. (2·4 × 102) + (1·6 × 103) Give your answer in standard form. 2. The population of Ethiopia is 5·2 × 107. Mastery How many million people is this? 3. Write 0·00062 in standard form. 4. The total area of South America is 17 840 000 km2. Write this area in standard form, correct to 2 significant figures. 5. Secure Work out. 3·58 – 14.9 6. Our classroom library was 131 history books. There are 65 fewer non-fiction books than history books. There are 34 fewer adventure books than non-fiction books. What is the total number of books in the library? 7. Work out. 302 – 147 8. Here are the charges for the activity camp. Monday to Friday Developing Half day Full day Full week (advance payment) £12·50 £25·00 £108·00 How much money do you save by paying for a full week in advance instead of 5 separate days? 9. What time is shown on the station clock? Emerging 10. Aleksandra runs an activity camp for children. The camp is open from 8:00 am until 5:30 pm each day. How long is the camp open each day? 11. Round 143 to the nearest 10. 12. Round 1289 to the nearest 100.
