L. I. To recognise fraction and decimal equivalents in the context of measures x How do you know that 1000 cm = 1 m is an error?

L. I. To recognise fraction and decimal equivalents in the context of measures Today we will be recognizing fractions and their decimal equivalents and using these to work out fractions of amounts of measures (e. g. ½ of 1 kilometre). Can you fill in the missing numbers hidden behind each blue square?

L. I. To recognise fraction and decimal equivalents in the context of measures What is each interval worth now? Hint: How many intervals (dividing lines) are there in each of the 10 boxes? How many lines are there in total? th 1/100 or 0. 01 There are 100 intervals in total. We have divided 1 litre (1000 ml) into 100 equal pieces.

L. I. To recognise fraction and decimal equivalents in the context of measures 100 ml How many ml is 1/100 th or 0. 01 of a litre? 10 ml

L. I. To recognise fraction and decimal equivalents in the context of measures 100 ml Each line or division is worth 10 ml. 1/100 th = 10 ml 2/100 th = 20 ml 3/100 th = 30 ml Carry on counting until you get past 100 ml. If you really want to annoy everyone in your household, count in hundredths all the way up to 1 litre!
