Convert between one metric unit and another. Know the relationship between metric units in common use and how they are derived from the decimal system. For example: Understand that for the same measurement in two different units: • if the unit is smaller, the number of units will be greater; • if the unit is bigger, the number of units will be smaller. Change a larger unit to a smaller one. For example: • Change 36 centilitres into millilitres. • Change 0.89 km into metres. • Change 0.56 litres into millilitres. Change a smaller unit to a larger one. For example: • Change 750 g into kilograms. • Change 237 ml into litres. • Change 3 cm into metres. • Change 4 mm into centimetres. Begin to know and use rough metric equivalents of imperial measures in daily use. For example, know that: • 1 gallon ≈ 4.5 litres • 1 pint is just over half a litre. For example: • A litre of petrol costs 89.9p. Approximately, how much would 1 gallon cost? See Y456 examples (pages 90–1). Link to mental recall of measurement facts (pages 90–1). Use units of measurement to measure, estimate, calculate and solve problems in a range of contexts; convert between metric units and know rough metric equivalents of common imperial measures 1000 0.001 100 10 1 0.1 0.01 km cm mm m – – – 8 0 0 0 4 3 2 7 3 0 8000 m = 8 km 4 m = 400 cm = 4000 mm 37 cm = 0.37 m 230 mm = 0.23 m","PeriodicalId":211234,"journal":{"name":"Problem Solving, Reasoning and Numeracy","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131312095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
