 So we've come outside today to learn a little bit more about how computers work and what we have is this is like a super computer made out of chalk and I'm going to show you why in a moment I need six volunteers are awesome what I'm going to do is I'm going to give you a disk and you need to go and stand on the circles from the far far away one so Riley you go away from that far away one Robert you go into the next one Ali you go over to the next one Kourish can you go over there Lewis can you go into the last one okay so I've got you guys here and this is all about teamwork and it's all about organizing data so you guys are the start of the data you're coming in and you're all out of order we've got the number five number two number one number three number six and number four and so before we start going into the super computer all I need to teach you is this symbol here what does this symbol here mean what does it mean Lewis smaller than bigger what's about the mathematical terms that we could use for smaller and bigger yep less and greater than awesome so what we have is the orange line is the less than and the blue line is the greater than so let's see how this works can you all take a step into the box can you say hi to the person next to you and give them a big smile not too cheesy now what you need to do is decide have I got the bigger number or have I got the smaller number and then the bigger number follows the blue line the smaller number follows the orange line go now you need to look around and check everyone's there and then you need to say hi and give the person a big smile go now decide who's got the smaller who's got the greater number do you guys know what to do do the next time I didn't see anyone smiling and saying hello smile and say hello now make your decision go nice perfect cool so I'm gonna get guys to turn and face me this way and we're gonna see what happened to our numbers can you turn and hold up your numbers please oh wow correct what number have you got what have you got Lewis okay what just happened to our numbers we put them into our super computer that's chalk that's like a computer super computer and we processed it and what happened huh do you think they would work with everything what kind of things could we sort in order do you think yep we could sort books what else yes what else yes what else yes what else what about big numbers really big numbers could we do that
