Nice. I just don't know where to start. Okay. Well, look, you've started here. That's that's cool. Yeah. C equals two B A equals d plus three. That's that's okay. Yeah. Okay. So Yeah, we've got at the moment four algebraic letters, A, B, C, D. Yeah, Yeah. Okay so we know let me see right if ball is next to an in between right? So if ball is on the inside of two items ball has b has either got to be here or here would you agree? Yeah so so we can we can sort of think about its position there right? Yeah there's a we can we can calculate the difference between these two can't we? Yeah the difference there has got to be one greater Yeah the the right hand side Yeah Yeah okay so look you've used this information that's c equals two B This you've used eight was d plus three. So the diary the diary is next to and on the immediate right of the abacus. Right, so a can be here can it? Yeah Yeah. No, and d can be here. So. So if b is here. A is here and c is there. Would you agree? Did you see what I just circled there? Right? So B B B is either here or here, right? Yeah, okay. But if b, if b were here, a cannot be there. So if it's between a and C, A would have to be here, Yeah and c would have to be here, okay. But that leaves d there. So b must be the second on the left, would you agree? Are you okay with what I'm saying? Yeah Yeah Yeah. So basically what's that what's that kind of strategy called? It's basically trialing possibilities, right? I've got two. So in terms of a math strategy, I've got two options for b. I've only got two options for b. So if I trial one option, Yeah and then I exhaust the possibiso, you say, okay, b would be here. So that means c would be here, a will be here, d will be here. Doesn't fit. So that's eliminated that possibility. So b must be second from the left. Now, does it help you? Can you do the rest? Now that you know be's there? I think if you look at this clue, you've got some more positions answered. Yeah, there's only one remaining possibility for d, isn't there? Yeah, Yeah. Okay. So we've got all the positions cbad. So what about the prices now? Oh sorry sorry I didn't mean to erase your so so it's C B D. Yeah. Because remember it's it's c plus d sorry, it's all three of those make make 20 so b plus a plus d make 20Yeah. So b plus a plus d are 20Yeah not d is 20Yeah. Oh Yeah, because it's the three presents on the right cost a total of 20. So this and this and this make 20. Is there a way of just making two equations? What's I think using this, you can make two equations with just two letters. Yeah if we try and use A, B, C and d, we've got too many letters. Are you feeling stuck or are you okay? I'm all okay. Thank you. Thank you. 拿点拿点粘土出去出去上课了,出去拿点水。Wait wait a second. Sorry. How old is she? Yeah, how old is she now? Almost almost five. Oh bessed she wants to see big brother, okay? What about substitution? What about substitution? Which would be replacement, replacing c with two b, right? What does that do? It eliminates c. It means we are no longer worried about the letter c. If we just call that two B, C is no longer there, right? And you've reduced the number of variables you have now. You don't need to worry at all about c. You just have two b and b Yeah. And a similar thing can be done here with a and d with replacement. If a is d plus three, then one of those letters can replace the other inside of an equation. Lovely. So now you've got two B, B D plus three and d. So all you've got now are two letters, two letters, and you can make two equations. Did you do simultaneous equations in class? Yeah, you did. So Yeah, once you've done that, you don't need these anymore. Just remember that d minus two b yethat's. What if you make equation one here? They all add up to what? And then make it wait. Yeah. Yeah, go ahead. 3D plus d plus three equals three b aequals. How much altogether? B plus b plus 2D plus three. Okay, but those two things are not equal, right? So Yeah Yeah so the two, the three b plus d plus three equals 19Yeah. Because look, this is the the three presents on the left cost a total of 19 pounds. Yeah. So three b plus d plus three equal 19. Three b plus d plus three. How how come do they need to be equal to set equal to each other? What what if you just did three b plus d plus three equals 19 plus the three presents on the layer? Yeah and so if you then take off the three of both sides, you've got that. Yeah and then the three presenon the right, you've got b plus two, d plus three. Equal 20Yeah because the three presents on the right are equal to 20 pounds. Yeah. And if we simplify that. It's that. What you have there is a pair of simultaneous equations. Did you do it where you multiply one equation and then you take them away. Okay. All so so now, now you don't even need the, now you don't even need the presence or anything, do you? You can just do that. Okay, so you got a value for b? Okay. So we've got d is seven, b is three. So. Yeah. Happy Yeah okay, nice all so look, it was just a a Christmas puzzle, but inside of that you've got forming equations, forming simultaneous equations, substitution, Yeah solving them obviously, and then some sort of trialing possibilities, eliminating possibilities. So there's a lot of maths inside. Just a plain old quiz about about presenokay. So let's let's talk about some more. What would you want to do algebra if you're doing lots of algebra already in school? Or do you want to look at some other stuff perhaps? Other stuff other stuff. Okay, so. Let us. Have a look at have you. Have you learned these before? Is this familiar? Let me just cut it out, put it on the board. Have you done these at all in class? No, okay, so look, let's let's start with just a pair of parallel lines. I believe you already know these, but let's just make sure we're refresh. Okay, so we've got a pair of parallel lines. Yeah. Okay, with a transversal. Yeah, you remember. Okay, so look, if I say this is 105. Firstly, how much is this hundred five? Okay, do you want to just label it for me? Then can you just put the 105 on? Lovely, okay, this would be what. 75. And there are two ways of showing that. There are two ways we can describe why that's 75. Can you see the two angle rules that work there? Can you remember them? No. Yeah, we've got a rule going on here, haven't we? Yeah angles along a straight line sum to 180. Yeah but we've also got this rule going on here. Can you remember that? Yeah that the two angles within the parallel lines also sum to 180. Okay, how much is this? 105, can you tell me at least one reason why? Why do you know that? These two are straight lines like they won't and when they cross till it stays in the same angle. So we've got the what I call the scissors rule. Yeah pair of scissors that the opposite vertically opposite angles are always equal. Yeah across to two crossing lines. Yeah so the 105 becomes a 105. Yes. But then we've also got this angle rule as well. So these are all kind of you know subsidiaries of the same rule because of the vertically opposite rule. This is also Yeah the z shape across Yeah. The z angles are equal, which the official word would be alternate angles are equal. Yeah. Nice nice okay. So have I forgotten any? I don't think I have have I that's all of our Yeah and then obviously we've got this whole you know all of these blah, blah, blah, all of these angles add up to how much? 360, right? So okay, so that those are like our kind of background rules for these, okay. Which are the circle theorems? Yeah, okay. So basically the circle theorem. So you didn't study them. Okay, the circle theorems are a set of angle rules Yeah angle rules using using circles Yeah. Okay. So the most basic, I suppose, is this one. What do you see here? A right angle triangle. A right angle triangle. Okay. And so the crucial thing here is basically that it might not be too visible, but that is a diameter. What's a diameter? The line across the circle, a straight line, a straight line across the circle. Crucially going through which point, the middle point, right? Going through the center. So it's the longest distance across the circle. Yeah, Yeah, Yeah. So we've got basically this this must be a diameter in this rule. Okay, this must be a diameter. This do you remember the name of this? This is a straight line across the circle, but it's not the diameter. That's called a chord. Yeah. Okay, Yeah so we've got a chord and then versus versus diameter. Yeah diameter would be the longest possible chord we can draw because it goes through the center. Yeah okay. So basically if you have a diameter which you do there, you know you can't see it. You can't see it. Super. Yeah. Okay. Any triangle you draw, any triangle you draw up to the circumference. Okay? So the diameter is the base and the third point, the site, the opposite vertex is on the circumference. That will always, always be a right angle. Okay. So so I could I could do this, right? And that would be a right angle. Making sense. Yeah. Okay, I could do that. And that would be a right angle. Yes. Okay. I think the next basic one is probably right next door to it. We have two pairs of angles that are the same. Yeah. Okay maybe just a as a side note this is called the angle the angle that one there the the right angle one the angle in a semicircle is a right angle sort call it yes look okay. These two which I call the bow tie roll yes. Is called angles in the same segment are equal. It's like a so they're a bit it's a bit boring the way we talk about it, but angles in the same segment are equal. What that means is this is a segment Yeah. Did you okay. So this is what we call a segment, a slice kind of slice that way of this of the circle. Like you've chopped the top of the orange. That's a segment. Yeah and the segment goes from here to here. Yeah and we can go up to the circumference and back down to the segment that way. We can go up up to the circumference, back down to the segment edge that way. Yeah so also there I could go to there and back down the other way to the to the circle edge. Yeah I could go from this segment edge up to there, back to there. All of those are gonna to be equal all of those because angles in the same segment are equal. Does that seem reasonable? Something you can Yeah to there could draw it up to there and back to there as long as I'm coming to and from the same segment. All of those angles are the same. Yeah Yeah okay. So like that, like that. This one, what do you see on the left? Can you describe what you see? What what do you see? Okay, we've got this. What's going on? Thatcenter the center. Okay, we've got an angle at the center. What else have we got on our picture? Three points on the second gment three points on the circumference. Yeah. Okay. And what else do we have? Four lines. Yeah so we've we've got straight lines. We've made an angle down to the circumference. Down to the circumference. Yeah and then and then we've drawn it back up to here. Yeah so we've made a delta shape. Are you doing latte ergreek? Ek, isn't that the letter delta? Well, that's the letter delta. We call it a delta hedoing Greek in school. No. No. Okay. All right. So so we've got a delta shape. Yeah. This angle is basically double that angle. This angle at the center is double the angle at the circumference. Yeah. You okay with that? Okay, so let me just put some values on. I'm just going to put it I'm just going to put this down here. Alright, just put a freshone on. Okay, so. Can you tell me the other two angles in there? Oh. Okay. How much is the blue angle? Yep. Nice okay. And in slightly less detail, okay, these are these are about just right angles and lengths and things. Okay. So these four don't worry about these two are the same. So. If that's 65, that is 65. Yeah. Okay, right. This is called a tangent. Have you ever heard that word? No, a tangent is a straight line which touches the circle in one place, only in one at one point. Okay. So it's a straight line basically going past your circle, but touching the circle's edge, the circumference, at a single point. So if that if that is a tangent and you draw a triangle, the angle between the tangent and the triangle and the opposite angle inside the triangle are equal. All right. So we won't do masses of detail on that one yet. But if this one is 70, the opposite yellow one is also 70. Yeah, okay. And here, just one, just one last one. If you've got two, if you've got right, do you see that these two are opposite these two angles and they are on a quadrilateral? Yeah here are the other two angles of the quadrilateral, and those two red angles are opposite each other. So you've got a quadrilateral inside of a circle touching the circle edge. Each each vertex of the quadrilateral. Yes. Yeah, Yeah. Okay. So we've got what's called a cyclic quadrilateral, which is a circle with a quadrilateral touching all four, all four corners, touching the circle, the opposites, the opposite angles. Make 180 degrees, okay? So the opposite angles make 180. So I'm going to fill in an angle for you. That's not right. That's way too big. Yeah, opposite angles make 180. So can you fill in all of the angles here? Nice. Yeah. Okay, so we'll leave that for today. And then what we'll do is next time we will revise it, I'll ask you to fill in some some questions for me. Yeah some to actually do some problem solving with it. Yeah. Okay, so we've done some angle work. We've done angle work, we've done simultaneous equations. Anything you can think of right now that you would like to work on from the school year so far that you're not sure about that might be more challenging or that you want to do more advanced work? Some like logical. Questions, by which you mean problem solving? Yeah, okay. So well, look, here's a problem solve. And whilst you do you have problem solving with have you done much? Oh, okay. Just before we do that, have you done any statistics this year so far? What is that? I mean, pie charts, histograms, line charts. Like you no using data, using data like sursurveys and representing data, was it difficult? Easy? It's like giving me a point and let me like draw a line on the graph. Okay, so easy. On okay all right okay so to look take a look at this I'm going I'm going to get you some problem solving using statistics is that okay? I'm just gonna to get it on my phone so that you can work on there at the same time Yeah Yeah. Okay, I'm just going to put them onto your chat. Okay. So any thoughts yet on this? No, but are you taking a look? You have to think, what are you feeling? Any thoughts or are you just you just taking a look? Yeah. New okay. Okay, I just added some pictures. I have no idea how to start okay what look I do you want let's let's do something else and we'll talk about this at the start next session. Yeah because let's take a look at some I think I think look sometimes my my first strategy would be to dive in and just throw some numbers at it right? Because you know it's gonna na be the digits zero through nine Yeah but I would try a little experimenting first but let's let's just do some statistical okay so look do let me just put these do you know pie charts? Yes. Did you do anything on pie charts this okay, alright, so here is a little problem solving with pie charts. Okay, so. Okay, let's let's take this one first. Here it comes, right? So. Oh, it's a bit a little, but it's not very flush. Okay, I'll try and get it a bit more going. I'm going to get it a bit more. Clear. Hold on. Hopefully, it is a bit more clear. So which pie chart goes with which graph do you think. I think a goes with f. And what's your reasoning for that? I think. Only that one, it looks like the black is more than yellow. Yeah, I think I agree that red is the smallest. Blue is slightly next small. Green is slightly next small. Yellow is Yeah. Okay. Yeah. All right. So what about b and c? Yeah, okay, nice. All right. So we're just visual problem solving there. Yeah, okay, right. So now let's take this. Which I will try and get bigger as well when we've got it on there, when we've got it on the board. Okay. All right, actually it's just it's just the first four questions. So the second, the questions 56 are not to do with this. Okay. So. These four first questions, okay? Then use the calculator if you wish. Aa. How I think you are correct first time. Yeah, okay. Aa. Yep. 82 so I'll be -26-38. Yeah Yeah okay. So you can use your calculator for these two if you wish. For 56. Not sure. No, okay, don't worry. Look, we'll continue this because I Oh Oh Yeah. I saw the 33 significant figusorry. I saw the three significant figures. Oh, okay, okay. Okay, so you did 360 divided by. 3737Yep. Okay so would be it would be 360 divided by 6.55 right? Arms. Yeah. Yeah, so still. Huin. No, no, nothing. So if you divide the 360 by the 6.55 by the number of degrees. Then it would tell you how many portions there are you. Yeah and so then it's more than 54 people, so it's 55 people Yeah. Yeah, I thought there shouldn't be I thought there shouldn't be 0.9618 person. Yeah, Yeah, Yeah. So we round it up. Yeah, because you're basically saying more than 50 quite you know, more than 54 people. Oops. Okay.
