2 showed us how the seeds in sunflowers are arranged according to these numbers. I realised then that what we were learning was relevant to things like plants and wildlife. My ‘maths brain’ suddenly woke up – and I was hooked on numbers! (1) I don’t know why it took so long, though – our teachers were always organising maths activity days and things, so I’d been involved in exciting stuff before. Interviewer: And your parents like maths, too … Lucy: Yes, Mum’s a maths teacher, and Dad does advanced maths training for business people. He believes some people he meets are much better at maths than they claim they are, they just don’t feel very sure of their abilities. They’ve all learnt lots of maths by heart at school, but he thinks they’re just not keen to try and apply it in case they make a mistake. (2) Interviewer: So have your parents always helped you with maths? Lucy: Yes, and they’ve made it fun, too – even my homework! Usually, though, they try to leave me to get on with that by myself, however hard it is! I’ve learnt a lot that way. But often when we go shopping, for example, they’ll ask me to calculate the change we’ll get – that’s really improved my mental maths (3). And sometimes Dad organises evening events to promote maths to adults, which I’m hoping to attend when I’m a bit older. Interviewer: So can you explain why you love maths? Lucy: Well, in my English class recently, we all had to write a poem about a tree. And when we compared them, everyone had written something completely different – but all of us had got the task right. But that’s not the case with a maths problem. You have to find the one correct solution – and that’s what really interests me. (4) I mean, there might be lots of ways of working it out, but it doesn’t matter as long as your answer’s right. And that applies to all the different areas of maths. Interviewer: And you recently took part in an international maths competition? Lucy: Yes, in my city. I wasn’t at all sure of myself when I arrived, but my teacher told me I had an excellent chance of doing well. So that helped, and by the time I went onto the stage to answer questions, my nerves had disappeared! (5) The other people were really good, though! By the end, I’d actually got quite a high score, but I knew all along I wouldn’t win. Interviewer: So what do you think you learnt from the competition? Lucy: Well, I was looking forward to being with people who all loved maths, no matter which country they came from – and I wasn’t disappointed! I realised it really didn’t matter if we couldn’t all understand each other perfectly when we were chatting, because when you wrote a maths sum on the board, everyone knew exactly what it meant! It was also fascinating to see how other competitors worked out solutions to maths questions – there were a number of different methods, just as my teacher had told me there’d be. Interviewer: And how do you think maths with feature in your life in the future? Lucy: Well, at the moment, I just like playing around with it, doing maths puzzles online for example. But

4 Program Host: Well, what are some of the things you should keep in mind? Guest: First, you need to have the right supplies: some kind of enclosure . . . Program Host: Like, like a cage or something like that. Guest: Yeah. [Okay] A full spectrum fluorescent light bulb and a basking lamp [Okay] , branches and rocks to climb on and bask on, a food or water dish, and something to line bottom of the cage. Program Host: Okay, well, let's get down to some the basics. What are the dietary needs of a bearded dragon? It sounds like a very carnivorous beast. Perhaps, uh, they eat fiery Mexican tacos or something like that. Guest: No, bearded dragons are omnivores. . . Program Host: Now, Omnivores? What exactly is that? Guest: Uh, creatures that eat insects, vegetable, and greens, the leafy parts of plants and their stems. (8) Program Host: Okay. You mean like, for example, carrots or something like that for example. [Yeah] Okay. Guest: Young dragons like Bert can be fed small crickets twice a day, along with some greens and shredded vegetables. [Okay.] And then as your dragon grows, you can increase the amount of greens and vegetables. [Alright.] And you can also dust the vegetables and insects with a calcium supplement to promote bone growth. Program Host: Okay, and what about water? Uh, what kind of needs do they have for that? Guest: Well, since bearded dragons traditionally live in arid regions, they obtain most of their water naturally from what they eat (9), so you have to be sure to feed them plenty of vegetables that serve as good carriers of water. [Okay.] You also spray them occasionally with a water bottle or provide them with a shallow water dish. Whatever you do, but sure to keep the cage dry, [Okay.] or else mold and bacteria can grow that could make your dragon sick. Guest: [Okay.], and finally, you mentioned about lighting earlier. What do you need exactly to keep your beardie happy and healthy? Guest: Having a full spectrum light and basking lamp are pretty key to raising healthy beardies. First, they need the simulated sunlight from the ultraviolet (UV) bulb . . . Program Host: Now, is that the full spectrum light that you mentioned? Okay. Guest: . . . to absorb rays [Okay.], vital to the production of certain vitamins (10), [Okay.] and the high body temperatures of a basking light to aid in the digestive process. Program Host: Now, what kinds of temperatures are you referring to when you talk about the basking area? Guest: Like ninety to a hundred degrees. Program Host: Okay, and I don't think they need sun tan lotion, right? [No]. Program Host: Okay, uh, so, perhaps then, I could put my beardie in an aquarium and just set him by the window which gets direct sunlight? Would that work?
