Mass

In Mathematics, year five have been learning about mass. Mass measures how much matter is in an object. The metric units for measuring mass include milligram (mg), gram (g), kilogram (kg) and tonne (t). 

Mass

Mass can be written in a number of different ways.

For example: 1600 g / 1 kg 600 g / 1.6 kg   

Take a look at Jenny Eather’s Poster below regarding metric conversions.

Capture

Gross Mass: The total weight – including the contents, packaging etc.

Net Mass: The total weight – not including the packaging etc. (contents only)

Take a look at year five learning about Mass!

What unit would you use when finding the mass of certain objects/animals and items? E.g. whale (t), paperclip (g) and person (kg).  

What are the different types of scales used to measure mass?

Ask your parents when they use mass in their daily lives and where they see g, kg and t.

    Dear Miss Azzopardi and Five White,

    I never thought that when you do mass it is not really hard when you get use to it and i can’t believe i am doing the test tomorrow.
    The different types of scales are spring scales,kitchen scale,bathroom scale,digital scale, balance scale and truck,weighbrige and rail road scale.

  2. Dear Five White and Miss Azzopardi,

    The different types of scales are spring scales, balance scales, digital scales, kitchen scales, bathrooms and truck scales/railroad scale/weight bridge scales. A Truck, car and a train can be used to be weighed in tonnes, a ant and a paperclip can be used to be weighed in grams and a human can be weighed in kilograms.

    Dear: Five white and Miss.Azzopardi,

    I have learnt a lot about Mass,
    A car can be tonnes, Paper clip can be grams and a person can be kilograms. Can you think of any other things that make grams, kilograms and tonnes?
    There are spring scales, balance scale, kitchen scale, digital scale and a bathroom scale. A truck and other heavy things are called truck scale, weigh bridge and railroad scale.

    Your sincerely,
    Alicia

  4. Dear 5W and Miss Azzopardi,
    Learning about Mass is incredibly fun! I was reminded how to convert from kilograms (kg) to tonnes (t), grams (g) to kg etc. For example when you convert tonnes to kilograms you have to multiply by 1000, and when you are converting kilograms to tonnes you divide by 1000. What did you learn interesting in Mass?

    Sincerely,
    Natalie

      Dear Natalie,

      I found it interesting that trucks have their own scale as well as a weighbridge and railroad scale. I knew that 1000 Kg is a 1 t because if 1000 g is 1 kg then 1000 kg is 1 t.

      Have a nice day,
      Grace

  5. Dear Miss Azzopardi and 5W,

    I love mass it is probably my favourite topic for maths because it is really fun and you get to put objects on scales. There are many different types of scales there is a spring scale, truck, weighbridge and rail road scale , balance scale, digital scale, kitchen scale and a bathroom scale. My mum told me that she uses mass when she is grocery shopping she uses mass because she has to find out the net mass of a can of tuna etc.

    Sincerely,
    Grace

    Dear Five White and Ms Azzopardi,

    Mass measures how much matter is in an object e.g A whale would have a large amount of matter, a pencil would have a small amount of matter.

  7. Dear Miss Azzopardi and 5 White,

    I think mass is very useful in our daily lives. The different types of scales used to measure mass are: spring scales, balance scales, digital scales, kitchen scales, bathroom scales and truck scales/weighbridge/railroad scales. My parents use mass when they go shopping and when they cook, they see g,kg and t when we go to the airport, when we see the weight of a product and when they measure spices.

    Sincerely,

      Dear Nathan,

      I think mass is very useful in our daily lives too! My mum goes to the shops and uses their kitchen scale to measure how much they weigh before my mum buys it.

  8. Dear five White and Miss Azzopardi,

    Mass is a great lesson i had it was so much fun weighing objects of scales!
    if we has to weigh a skyscraper we would use tonnes,if we had to weigh a human being it will be in kilograms and if we had to weigh an eraser it has to be in grams. In mass i learnt some new scales that i didn’t know about just to name a few the truck scale,the spring scale,bathroom scale etc.
    My mum used mass when we are weighing ingredients for making food or cakes.

    Kind regards,
    Josephine

    • Dear Josephine,
      I agree that Mass was a fun subject! If you were measuring a car you would use the measurement (kg), a house (t), a luggage (kg) an apple (g) and a table (kg).

      Sincerely,
      Natalie

      Dear Josephine,

      I also loved mass and it was super fun weighing objects with you and my mum also uses a kitchen scale if she has to find the mass of an item fr cooking or baking.

    Dear Five White and Miss Azzopardi,

    The different types of scales are balance scale, bathroom scale, digital scale, kitchen scale, spring scale and a truck/weigh bridge/ railroad scale.
    Something’s you can weigh in tonnes are trucks, trains, helicopters, cars, caravans, planes and whale’s. Something’s you can weigh in kilograms are people, some animals and food. Something’s you can weigh In grams are pin, paper clip, ant, feather and food. My dad told me that he uses mass when he is at work with his truck and my mum said that she uses mass when she is going to the airport and when she is grocery shopping. When do you use mass in your life?

    Yours Truly,

    Dear Five White and Miss Azzopardi,

    In maths we have been learning about mass. In mass we have learnt a lot of things for example the definition of mass which is mass measures how matter is in an object. We have also learnt about how to convert milligrams to grams, grams to kilograms and kilograms to tonnes. These are just some of the things we have been learning about in mass.

    Sincerely Anthony

    Dear Five White and Miss Azzopardi,

    I enjoyed learning about Mass. Mass definition : Mass measures how much matter is in an object. Scales

    * Digital scale
    * Balance scale
    * Kitchen scale
    * Truck Scale
    * Weighbridge scale
    * Railroad scale
    I cant wait to learn about our new topic and I hope I enjoy Length more than I did with Mass. Thank you Miss Azzopardi for teaching me lots !

  16. Dear Miss Azzopardi and five white,

    If you were to find the mass of something that is small e.g coins,pencils or a rubber you would use the unit grams, if you were to find the mass of something that weighed heavier such as a human or a suitcase you would use the until kilograms, if something was really heavy you measure in tonnes. this can include vehicles like cars and trucks.

    Different types of scales include:
    – A spring scale
    – A bathroom scale
    – A balance scale
    – A weighbridge scale
    – A digital scale

    My parents use mass in their daily life all the time, when cooking my mum uses grams to buy and measure ingredients. My dad uses measurements such as kilograms, to measure the amount of material he needs on his job.

    Yours Faithfully,
    Jennifer E
