More clock flowers

We used the Scratch Clock Flower Project and noticed lots of things - have a look at our comments.
Then we together looked at which size jump "fitted", so that the jumps only went round once to create nice neat petals.

We scanned them and coloured them in quickly on Paint:

Meanwhile, Rose, Marie and Gabrielle volunteered to try a similar thing with Cuisenaire rods. Their line of rods had to be 60 long. Only numbers that "fitted" exactly into sixty could be added.

They did a great job. The line at the top is the twelves, made of ten+two because we don't have any twelve rods. Can you see any other big factors of sixty that are missing?

Clock Flowers on Scratch

After some class work on clock flowers last week, I wrote a little bit of code on Scratch to make some more. You can make "petals" for the flower that have jumps of between 1 and 22. Try it out. Click the green flag to begin.

Clock Flowers

We've been looking at time on analogue and digital clocks this week in Year 4, so we also did some clock counting, where, like the minutes on a clock, once you get to 59 you go back to zero again. It's a kind of round number line.

We looked at different sizes of jumps you could have going round the clock. The jumps look like petals on a flower, so we called them clock flowers. We all chose different sizes of jumps, drew them out, and then had a look to see...

What do I notice?

Mr Gregg asked Justus if his line would visit every mark around the clock. Justus saw from the vertical pattern in what he'd drawn that all the numbers would be included.

That's some great noticing!
Here's a slideshow of some of our work:
