How did you go with measuring Noah’s ark yesterday? It might have been hard for some of you to find a big enough space to do it, but perhaps you got an idea of how big it was. Perhaps you found it difficult to measure something so big, with quite a small measuring tool? 


Did you end up measuring your driveway again? Did you get the same measurement as the first time? Hopefully you realised that when we measure something, accuracy is very important. If you are using a stick, you need to place it down so that you don’t leave any gaps and you need to measure in a straight line. 

Metres, Centimetres and Millimetres

A metre – 1/10 millionth of the quadrant of the earth’s circumference from the north pole, through Paris, to the equator. On the human body, a metre is roughly an arm and a body – from the tips of your fingers with your arm outstretched, across your body to your shoulder. Most countries in the world use what is called the Metric System. It’s the system of measurement that uses metres, centimetres and millimetres. There are 100 centimetres in a metre and 1000 millimetres in a metre. 


Centimetre – 100 in a metre

Millimetre – 1000 in a metre

Draw a table in your main lesson book (large red book). Measure at least 2 things using metres, centimetres and millimetres. Of course, you can measure as many things as you like, but please do this many in your books. At the bottom of the table you will see that I have already included 3 measurements. These are measurements of things that I know you all have. See if you can work out what I have measured.


Do not copy my examples of the giraffe and the window.



Do the following sums in your Maths Practice Book (medium red or orange book). You do not need to write out the questions, just write the sum and work out the answer.


  1. The backyard wasn’t big enough to measure Noah’s ark. The width of Noah’s ark was 50 cubits and the width of the backyard is 23 cubits. How much shorter is the backyard?

  2. The length of the backyard is 50 cubits. The length of Noah’s ark was 300 cubits. How many lengths of the backyard can fit into Noah’s ark?

  3. In a two-story house, the measurement from the floor to the ceiling is 362cm on each level. The pointed roof is another 154cm. How high is the house in centimetres?

  4. There are 100 centimetres in a metre. If a tree is 800cm high, how high is it in metres?




  1. The street wasn’t long enough to measure Noah’s ark. Noah’s ark was 450 feet long and the street is 281 feet long. How much longer than the street is Noah’s ark?

  2. The backyard is 19 metres long. How long is it in centimetres?

  3. When I was measuring Noah’s ark, I got tired and stopped to rest a couple of times. I measured 139 feet, then 78 feet and finally, after another 26 feet I was too tired to keep going. How many feet had I measured altogether?

  4. A backyard is 2500 centimetres long. How long is it in metres?
