Learning Goal: I can estimate and compare measurements
Today you are going to be looking at some Guinness World Record measurements, and finding items around your house that you can compare with these measurement! You will need some measuring equipment – a timer, a ruler/tape measure, some scales.
Watch this video to learn about your lesson activity for today:
First, draw up a table in your book like the one below:
Or download a copy to fill in on your computer or to print here: estimate and compare measurements table
|
Record measurement |
Type of measurement |
My estimate |
Actual result |
|
Fastest bowl of pasta eaten – 27 seconds |
Time/amount of food |
|
|
|
Longest fingernail on a person – 89 cm |
Length (in centimetres) |
|
|
|
Heaviest apple – 1.8 kg |
Mass/weight (in kilograms) |
|
|
|
Tallest man – 272 cm |
Length (in centimetres) |
|
|
Next, think about an item in your home that you could try and use to equal that measurement and write down your estimate.
For example, the world’s fastest time to eat a bowl of pasta was approximately 27 seconds. What is something that you think you could (sensibly and reasonably) eat in 27 seconds? My estimate was that I could eat 5 grapes in 27 seconds. I chose grapes because they are small and easy to eat, and I had some at home so I knew I would be able to test it out.
Write an estimate next to each of the records in the table. Make sure you think about what it is measuring (time, length, mass).

Then, once you have recorded all of your estimates, test them out! I got my grapes ready, then set a timer for 27 seconds. My actual result was that I could eat 8 grapes in 27 seconds.

Finally, see if you can beat your own record for skip counting! Set that timer for 1 minute and see how far you can get. Then look over your work, set the timer again and see if you can beat your first attempt!
Upload your completed table to OneNote. You might also like to share any photos of your world record matching attempts.
Meredith sent me an email with the small group timetable this week, but it said that we had Maths today. Do we do this work, or is it separate?
Meredith might talk to you about it in your group, but if you finish your other work you can go ahead and work on this independently
The measuring tape does not go as far as 727 cm so I doubt this man could have been that tall
You might need to read it again – it is 272 cm, not 727. Some measuring tapes might still not go that far so you might have to figure out how to do it!
Yikes – 🤨
Hi, I’d just like to say that I do not know how to manage this task, and am rather confused 🙁
That’s ok Maya! Don’t worry about it for today. Remember, that if you are feeling confused during the day you can email your teacher or drop into the open Webex in the afternoon to discuss it.
Hi Maya,
It would be great to see you pop in during our open session so I can support you with this.
