Sports day #1 & Maths before bedtime

This morning we headed over to Derby for a Sports Day (our first of two in two days).  It started raining pretty much as we arrived and didn't stop all day.  Enthusiasm was dampened somewhat, but we did have several races before we admitted defeat.  K doesn't generally like to join in these things and true to form she didn't today, instead she started building a den in a nicely sheltered group of trees and bushes.  M joined in selectively, and was very pleased with herself when she won the 5-7 year old running race and one of the two three-legged races she took part in (with different partners neither of whom she'd met before the day).
The planned picnic lunch in the park wasn't going to happen, but happily we retreated to the house of friends along with another family who we'd met a couple of times at birthday parties but didn't really know.  All six children (4 girls, 2 boys aged between nearly 9 and about 3) played beautifully together with barely any intervention from the grown ups at all.  So the mummies got to have cups of tea and chat - a lovely unplanned afternoon of the best sort!

When I'd finally torn my girls away (It was tricky.  There was much grumping and arguing with each other and me), we got home at about 5.30pm and it was still raining, having not stopped all day!  Having realised that since our Sports Day #2 is the Fun Club one (rearranged due to rain from a couple of weeks ago - but this time we have a plan B as we can get in the hall if necessary) and I was taking the Box of Rocks to go in the resource library there.  Thinking that it's not out of the question that K &/or M would be fairly likely to suddenly show an interest as soon as the sizeable box is no longer taking up room in our house, I decided to photograph all of the specimens as a reminder.   Here's a few examples:

Granitic igneous rock

Chalk (sedimentary)

Metamorphic Schist

Rather beautiful Malachite

I also remembered (after reading a few chapters of Titus Rules OK! to K & M for bedtime - my impression of the Queen is particularly popular) that we'd borrowed something from the resource library, which K had taken a fancy to several months ago.  I couldn't remember how much we'd talked about it, so asked K if she remembered about it and we had a look together.

It's a flip thingy that shows 4 different ways to express the same thing.

Most 1/x when it comes to the fractions, but a few weren't, so we talked about simplifying fractions.  Clearly 2/4 = 1/2, so it's not to big a step to see that 6/10 = 3/5.

But far and away the favourite was the 1/3. 

The concept of 0.3 recurring was greeted with utter delight!
