The number zero  By :Kekeli Ayivi   INVESTIGATION   Identify the Problem

A lot of people don't know about the history of zero.
Explain the Problem We need to create a PowerPoint presentation about the history of the number zero so that people who don't know about it but want or need to know about it(e.g for a assignment in school) have a resource to find out about the history of zero. Research and Analysis


 * Investigation questions the number Zero **

1. Where did the number Zero come from? Mesopotamia ( [] ) ( [] )

2. When did it spread to Europe? In the 12th century ( [] ) ( [] )

3. Name the man who brought it to Europe? Leonardo Pisano (aka Fibonacci) ( [] ) ([] )

4. What city in Italy first used the number Zero? Milan ( [] )

( [] )
5. Describe what was wrong with the roman numerals number system? They don’t have a zero, negative numbers and fractions. ( [] )

6. Why were people afraid of the new number system? They had to change the currency and where afraid of being cheated by money changers. ( Video)

7. Contrast the roman numerals to the new number system. Roman numerals are represented by letters Hindu Arabic numbers are numbers that are numerical. ( [] )

8. What difference did the new number system make in Europe?

9. Plan your own number system. 2=10 3=2 4=30 5=40 6=50 7=60… 17= 60+1=61

 * 0 || 1 || 2 || 3 || 4 || 5 || 6 || 7 || 8, 9 || 10,11 ||

10. How could the number Zero been invented in two different parts of the planet by two totally unrelated civilizations at about the same time?

i did some research about the number zero. i found out a lot about its history and how its used in different ways.i also tried to make my own number system. i think i now know how ancients used numbers and how important the zero is. E.g. the ancient Romans had a very simple number system they didn't have zero; so they didn't have fractions or negative numbers. ======

//Here are some tips to help you make an effective class presentation://

 * ====//§ Involve your classmates. Ask questions or involve your classmates in your oral presentation. This is a great way to keep them awake and get them more interested in what you have to say.//====
 * ====//§ Use pauses and vary the tone of your voice. If you speak too fast or too slow, you're sure to lose the attention of your classmates. Talk at a nice pace, use a pause before you make an important point, and vary the tone of your voice.//====
 * ====//§ Make eye contact with everyone. Focus your attention on each person in the audience. Don't look to long - just recognize each person at some point during your talk.//====
 * ====//§ Use a visual aid. Bring a poster, PowerPoint, or give out a sheet of paper with notes. A visual aid can help you promote your ideas.//====
 * ====//§ Don't read to your audience. It's okay to bring notes with you when you give a presentation - just make sure not to stare down and read them. Your notes should be a serious of brief bullet points to give you reminders or talking points. That's it.//====
 * ====//§ Be enthusiastic. The more positive and upbeat you are -- the more it can inspire the classroom.//====
 * ====//§ Practice your speech. Practice giving your speech out loud. Try to pretend like you're actually giving it.//====
 * ====//§ Summarize at the end. Make your point clear at the end. Summarize what's important about your speech so everyone remembers exactly what you spoke about.//====

I found out what makes a good presentation and i think the most important points are the ones above. I think its most important ones are: that the class doesn't get bored so you should have like a little quiz in the presentation or just ask some questions here and there. It's also important not to read from a paper and know what you are going to say or have notes so that you look at the audience and not at the papers. the most important one is i think to use visual aid. If there is only writing the class is going to get bored very easily and is probably not going to pay attention for a long time. I also found out that its good to have your one notes of course printed out but also audience notes so that the audience doesn't get bored.

Design Brief In the next four weeks I am going to design and make a PowerPoint presentation, using the research I did on presentations and how the ancients used numbers, to inform people about the history of zero. Product Specification Test Plan

CREATE  Final Product **MASTER SLIDE** On the slide master i changed the font for all slides. I also changed the background for all slides except the first. I changed transitions and animations so they are the same for every slide. i did all that so my PowerPoint presentation doesn't look messed up and you don't concentrate on animations or the background instead of what the presentation is about. **FINAL PRODUCT** media type="file" key="ZERO.swf" width="504" height="1.5; height: 378" media type="file" key="ZERO.swf" width="872" height="872" Changes made to the original Design The background of my PowerPoint is still red but its a bit different to how it is in my design. Instead of solid fill i thought it looks better if it has a gradient fill. The title of the third slide is different its "zeros of the world" instead of "who else uses zero?". I think the title is better, I took it from my second design. For the third slide I changed the design to 1 picture with all different zeros instead of 4 little pictures with zeros, because I couldn't really find pictures of zeros in different number systems. I also added 1 slide. Instead of having the introduction on the title page I made a separate slide for it because I just thought it would look better if only the title and my name were on the first page. i changed the writing instead of castellar i took Aharoni because it was easier to read. Changes made to the original Plan I pretty much followed my plan but i did it all in a bigger time frame since the deadline has been changed to the 24th. I didn't do as much work at home as i planned to because i had more time in class and didn't really need to do as much in my free time. I did all the things i planned to do but not at the same time. for the first one part of my plan i did it all how i planned it but the second and third part got mixed up a bit. i did third and fourth slide first and then got the pictures for everything in the very end. slide five and six i did at home instead of the last lesson because i used that lesson to improve my PowerPoint presentation. EVALUATE  Results of tests //**__(chantell)__**// || ==**results Kekeli**== || i don't have enough information || other comments : in the history of zero there was a fact with a place that no one knows and where it is( Mesopotamia). it would have been better with hyperlinks it was okay but not that eye catching commented by: Chantell Alfonso my product compared to my design specification is good and will be able to inform people about zero but, it's not telling people enough about it. Recommendations for improvement i could do more research so have more information on each slide and i should also do it as much as my design as possible.
 * ==**test**== || ==**results**== || ==**comments**==
 * enough pictures?,i ask if it has enough pictures || yes ||  || yes ||
 * colorful?, i ask if its colorful enough || yes || their could be more different colors but its colorful enough || yes ||
 * right amount of information?, i ask if i have too much information or not enough || no || not enough || no
 * 6 slides? ,i check if there are at least 6 slides || yes ||  || yes ||
 * not more than 10 slides?, i check if there are less than ten slides || yes ||  || yes ||
 * slides titled?, i check if all slides are titled , i ask if the titles are good || yes ||  || yes ||
 * bibliographies slide?, i check if there is a bibliography slide and if there are all the links i used || yes ||  || yes ||
 * pictures relating to the subject? ,i ask if the pictures are good for that slide || yes ||  || yes ||
 * title in old English writing? ,i check the master slide if all the titles are in //old English writing// || yes ||   || yes ||
 * writing in //castellar//?, i check the master slide if the writing is in //castellar// || no || writing in Aharoni || no ||

i think it was good that the animations for my PowerPoint were the same but maybe i should take a more interesting animation than to let it fly in because to some people it looked a bit boring. next time i should also explain more especially the places ( e.g Mesopotamia ) so that people know exactly were it is and what it is i think my PowerPoint didn't really need hyperlinks because its supposed to be presented to a class and you should only go the way the slides are, but maybe i could put a hyperlink for the next and previous page. i also did the test Chantell did and i got the same results as her so maybe when i was making my PowerPoint i could have looked more at my design specification and include everything i wanted it to have to make it better.

Self-evaluation of your execution of the design cycle ** investigate : ** i should have made way more research to have more useful information in my final product ** design : ** i spent too much time drawing my first design and then i ran out of time and didn't put as much work in the third and fourth as i did in the first. ** plan: ** i think my plan is pretty good by i should have been more exact with the dates ( they have been changed) ** create: ** i didn't look at my design specification while creating the PowerPoint, so i left out some parts ** evaluate: ** more people should look at my PowerPoint so i can get an average
