Select and use standard metric units of measure and convert between units using decimals to two places (e.g. change 2.75 litres to 2750 ml, or vice versa) I can convert one measurement to another using a related unit. I use decimals to do this Participate in a whole-class debate using the conventions and language of debate I can take part in a whole-class debate What measurement is 10 times as big as 0.01 kg? How do you know that it is 10 times 0.01 kg? I divide a measurement by 10, and then again by 10. The answer is 0.3 m. What measurement did I start with? How do you know? The height of a model car is 6 centimetres. The height of the real car is 45 times the height of the model. What is the height of the real car? Give your answer in metres. How do I write 5 metres 6 centimetres as a decimal? Debate with the class the usefulness of various benchmarks for estimating measurements. For example, how useful is it to know that a door is roughly 2 metres tall? What other heights can be estimated using this benchmark?
