 Name…………………………………………………………………………. Date …………………………………………………………….. LO: to convert weights (1) 1 kg = 1000 g so that means that… 1000 g = 1 kg 2 kg = 2000 g so that means that… 2000 g = 2 kg You carry on. Keep a check on those zeros! 3 kg = ______ so that means that… _____ = 3 kg 4 kg = ______ so that means that… _____ = 4 kg 5 kg = ______ so that means that… _____ = 5 kg ___ = 6000 g so that means that… 6000 g = ___ ___ = 7000 g so that means that… 7000 g = ___ ___ = 8000 g so that means that… 8000 g = ___ ___ = 9000 g so that means that… 9000 g = ___ ___ = 10000 g so that means that… 10000 g = ___ Name…………………………………………………………………………. Date …………………………………………………………….. LO: to convert weights (1- continued) But what happens if you only have half a kilogram? How do you write this? How do you convert it to grams? Remember 1 whole kg is 1000g, so half of 1000g is 500g. Half a kilogram is sometimes shown like this >>>> 0.5kg. So… 1.5 kg = 1500 g so that means that… 1500 g = 1.5 kg 2.5 kg = 2500 g so that means that… 2500 g = 2.5 kg You carry on. 3.5 kg = ____ g so that means that… ____ g = 3.5 kg 4.5 kg = ____ g so that means that… ____ g = 4.5 kg 5.5 kg = ____ g so that means that… ____ g = ___ kg 6.5 kg = ____ g so that means that… ____ g = ___kg _____ = 7500 g so that means that… 7500 g = ____ kg _____ = 8500 g so that means that… 8500 g = ____ kg _____ = 9500 g so that means that… _____ = ______ _____ = 10500 g so that means that… _____ = ______ Name………………………………………………………………………….

Date …………………………………………………………….. LO: to convert weights (4) 1000 g = 1 kg so that means that… 1 kg = 1000 g But what happens when you have less than 1000 g, lets say 800 g. How do you convert this to kg? Remember that 1000 g = 1 whole kg, so when you have any amounts less than a whole kg you need to use a decimal point. 100 g = 0.1 kg so that means that 0.1 kg = 100 g 200 g = _____ so that means that ____ = 200 g 300 g = _____ so that means that ____ = 300 g 400 g = _____ so that means that ____ = 400 g 500 g = _____ so that means that ____ = 500 g 600 g = _____ so that means that ____ = _____ 700 g = _____ so that means that ____ = _____ 800 g = _____ so that means that ____ = _____ 900 g = _____ so that means that ____ = _____ Name…………………………………………………………………………. Date …………………………………………………………….. LO: to convert weights (4 - continued) But what happens when you have more than 1 kg, for example 1100g. How do you convert this? Partition the number like this> 1000g and 100g. You know that 1000 g is the same as 1 whole kg = 1 kg, and from doing your work on the other sheet you know you write 100 g as 0.1 kg. So, 1 plus 0.1 = 1.1 kg. 1200 g = 1000 g + 200 g = 1 kg + 0.2 kg = 1.2 kg 2700 g = 2000 g + 700 g = 2 kg + 0.7 kg = 2.7 kg 3800 g = ____________________________________________ 4400 g = ____________________________________________ 5900 g = ____________________________________________ 9200 g = ____________________________________________ Look carefully at these next questions. Look how many whole kilograms we have to help you work out the answer. Partition the amounts. For example 1.4 kg = 1 whole kilogram and 0.4 of kilogram. You know that 1 kg = 1000g and that 0.4 kg = 400g. So add them together and your answer will be 1400 g. 2.7 kg = 2 kg + 0.7 kg = 2000 g + 700 g = 2700 g 3.6 kg = _____________________________________________ 5.6 kg = _____________________________________________ 8.1 kg = _____________________________________________ 8.3 kg = _____________________________________________ 9.4 kg = _____________________________________________
