    Hey Team, i have a quick question about the 1st perimeter task. There are 2 that have us a little confused. As for most of them, the measurement on the side e.g 4 cm matches with 4 blocks, 3 cm and there is 3 blocks and so on. one of them has a 3 but only has 2 block width and the other has a 3 but is a 4 block width. We are confused as to which we count, the number that is displayed or the amount of blocks there are and we weren't sure if this was an error with the numbers because all other measurements match the amount of blocks for those particular questions. Kind regards

    Hi Anna
    I agree this is confusing. So confusing I'm having a second go at answering your question. I think in the perimeter sheet they have carefully matched the numbers to the squares as you counting one to one right around the outside. Where as to calculate area because your strategy changes and you are multiplying the two numbers (length by width ) they have not been as accurate with their scale in matching the bricks to the numbers. You certainly go me thinking.

      Hi Trish, thank you for your response. Im unsure if you quite understood my question. Yes for area its different but in regards to my question it only relates to perimeter. If you could number them from 1 - 9, the confusion was coming from number 2 and number 8. I just wanted to know if those 2 were errors as the numbers for length did not match the number of boxes. Thanks Trish

    Oh yes for sure Anna I understand now.
    Yes they have to be errors. Number 2 should (2+5+2+5) and number 8 should be (4+3+4+3=) gold star for you guys. Thanks for all your hard work. Looks like its very busy in your bubble.
