    Hi Lachlan
    What a good way of explaining how to round up to the nearest 'ty' number and then 'pay back' what you'd rounded! We really liked the way we could see each pen stroke - it was like you were actually writing in front of us. We're going to have a go at showing our strategies too on our class blog. Hopefully we'll do a good job like you did.

  2. Well done Lachlan. I believe you used "iShowU" software to make this video explaining your maths. I use that a lot too. If you wanted a free programme that you could download to use at home, you can do the same thing with Jing. You can download it at http://www.techsmith.com/jing.html
    I wonder if you know how to write up your equation using brackets?
