Measuring Area

This morning in maths each group had to sort objects from biggest to smallest by 
measuring the area of each object.
'Area' means the amount of flat space that an object takes up.

We discovered some interesting ideas as we worked:

You can't compare 2 objects by measuring with different units!
That wouldn't be a fair comparison.

If we choose measuring units that are too small, it takes a lot of counting!

Some of our units overlapped the object we were measuring. That made it tricky to count the number of units used!

But we worked together as teams and overcame the problems.
Yay us!

How does working as a team help us in our learning?


  1. I love that you work as teams its so much more efficient and its fun too! When one person has an idea do you find that someone else builds on it and then someone a bit more until you have something that works? The first idea might not be the greatest but is so important because it gets everyone else thinking.

  2. Dear B4,

    I like the teamwork that all of you show to solve these problems. That's such a great trait to have!

    We learned about area a little bit earlier in the year. We probably use different units of measurement than you do though. We use inches, feet, and yards. I'm guessing you use millimeters, centimeters, and meters! It's interesting how different countries use different types of measurement!

    My students created a video about area earlier this year. Hopefully it can help you as you learn about it too! Here's the link http://mravery.edublogs.org/2011/02/05/area/.

    Good luck and keep up the great work!

    Your blogging buddy,

  3. Dear Mr Avery
    You are right - we do use centimetres and metres and millimetres in New Zealand. (Did you notice we spell it differently also!)
    At the moment though, we are measuring with non-standard units. Some older children will get to use standard units also.
    When Mrs McKenzie was young we measured with inches and feet, but New Zealand changed to a metric system in the late 60s - early 70s.

    Thank you for the link to your post on area.

    Mrs McKenzie and B4

  4. We can use the blox or some cards
    or we can use some little disc or the ones or the tens or the big blox or the laego
