Using the special bunny clock, one month in the potato fields lasts only five minutes. To support this, in The Number Devil, the number devil says, "Time runs faster here in the potato field. A month only lasts five minutes. At least when you use the special rabbit clock I just happen to have with me." This shows that with the special bunny clock, and ONLY with that clock, can a month last five minutes.
ReplyDeleteI would like to answer a question that no one has answered yet and I would like to say that the type of model he used to show the rabbits is that for example he shows 1 rabbit then 2 rabbit then 3 rabbit and so on untill you get to 21 rabbits. So thats how he showed the model.
DeleteI agree with Christopher because on page 118 it says "4,181 couples. Which means that in five minutes there will be 6,765." So this means that rabbits will keep adding up in only 5 minutes.

ReplyDeleteI agree with you but it'd be more of a stronger response if you used evidence to support this instead of bluntly responding.
DeleteTo count the number of rabbits without counting them one by one, you could think of the Finobacci sequence and count it like that. For instance, 1,1,2,3,5,8, and so on. when the sequence reaches the number 2, that's the amount of rabbits born. Then after that, in three months 2 more rabbits are born.
ReplyDeleteI agree with you
DeleteFor bonacci numbers you have to take the last two numbers and add them together and keep going down the line
ReplyDeleteThis comment has been removed by the author.
DeleteYes, Iagree but what is that you add in the equation the addend and the addend, addend or sum,or all of them together.
DeleteI agree with Derek but I think that you should add an example or state where you got your answer
DeleteDo you know the mathematical term for bonacci numbers?
Deletethe type of data display that is shown to use the rabbit problem was a table that had tittles that explained rabbit clock, the parents, the amount of children, grandchildren, great grandchildren and lastly the bonacci numbers 1,1,2,3,5,8,13,21
ReplyDeleteI agree with you because in the book the number devil states, "Let me show you the the rabbit list I've put together." Which shows how the bonacci numbers by using this rabbit scenario as Aliana pointed out.
DeleteThe number's that begin the Bonacci pattern are the numbers 1+1. The number is 1+1 because a Bonacci pattern is when you add the sum with the addend and get the same sum as the next equation.For example 1+1 is 2. Than you would add 1 and 2 to get the following equation. So the equation at the bottom would be 1+2. So if you get the pattern it would be a easy shortcut to find equations in order. The number devil also describes this pattern like hopping numbers because adding the addend and the sim every time will get you the next equation.
ReplyDeleteI agree with you Jairo because the pattern is shown through out the Bonacci numbers
DeleteI actually disagree because that's in chapter seven when Robert and the number devil build the triangular figure with the cubes which is supposed to be similar to the coconuts. To add on that wouldn't work because when you get to five, 3+1 doesn't equal 5, it equals 4 so it doesn't work with this scenario.

ReplyDeleteI would like to answer a question that no one has answered yet and I would like to say that the type of model he used to show the rabbits is that for example he shows 1 rabbit then 2 rabbit then 3 rabbit and so on untill you get to 21 rabbits. So thats how he showed the model
Why did he show the rabbits? What was his point? Be more descriptive
DeleteHe showed the rabbits to show us when rabbits give birth its like a chain reaction for example when the mother rabbit gives birth the daughter grows up and give birth and it keeps going and going like a chain reaction. By the way that was a very good question Fatoumata.
Deleteyou can calculate the number of rabbits being born by looking at the table. you would first have to figure out the pattern that is being shown form the beginning of the table to the end. In addition you would also try to figure it out by looking at the rabbit clock.
ReplyDeleteThe rabbits were telling Robert that it takes a month to grow up and then there fur turns brown. Then they want to have babies,that takes another month for the babies to be born. One boy rabbit and one girl rabbit. Two a month is enough and then it repeats. " Robert said that he has to go to school tomorrow" the number devil interrupted and said "Time runs faster here in the potato field" A month lasts only 5 minutes when you use the special rabbit clock. The hand shows months not hours, the bell rings every time a month goes past. The rabbit clock ran on and on rabbits kept on coming.
ReplyDeleteAndrew I like your answer but next time could you paraphrase it because Ms.Brown does not like when people copy directly fro the book
DeleteUsing the special rabbit clock it takes 5 minutes for a month to last. He had two large rabbit ears but only one hand. But the one hand shows months not hours, so if it is in the middle of 0 and 1 it means that it is in the middle of the month. The bell rings every time a month goes past.
ReplyDeleteI agree with you Angel because the rabbit clock takes 5 minutes for a month.
DeleteI agree with you Angel because each month is taken for 5 minutes and for each 5 minutes there are a new set of rabbits
DeleteRodolfo you could of said more things or details to support your answer just a tip.
DeleteI agree because the rabbits clock is different than a regular clock
Deletethe rabbit clock is different because it works with months instead of time

DeleteI would like to answer a question no one has answered yet the Fibonacci sequence is a set of numbers that starts with a one or a zero, followed by a one, and proceeds based on the rule that each number it is equal to the sum of the preceding two numbers
ReplyDelete2) Which number begins the Bonacci numbers? Identify the mathematical term that refers to the Bonacci numbers. The mathematical term that refers to bonacci is The Fibonacci sequence a set of numbers that starts with a one or a zero, followed by a one, and proceeds based on the rule that each number (called a Fibonacci number) is equal to the sum of the preceding two numbers. In the book it states "A capital idea! and like most good ideas, it begins with - what do you think?- a one.Or, rather, two ones 1+1= 2 . The number that begins bonacci numbers is 1
ReplyDeleteI agree with you Mia, i also liked how you answered the question you chose.
DeleteThe Fibonacci sequence is the sequence 1, 1, 2, 3, 5, 8, 13, 21,... where each at a later day term is generated by adding the two previous terms together
ReplyDeleteThe type of data display that is used to show the rabbit problem is 1,1,2,3,5,8,13,21. I say this because in the book it states "You take the last two numbers and add them together and keep going down the line" This evidence supports my claim because "1,1,2,3,5,8,13,21" has to be added by the last two numbers so this makes them Fibonacci numbers
ReplyDeleteUsing the special rabbit clock one month in the potato fields lasts only five minutes.

ReplyDeleteUsing the special rabbit clock a month lasts 5 minutes in the potato filed. I say this because in the book it states " Time runs fast her in the potato field. A month only lasts 5 minutes. At least when you use the special rabbit clock i just happen to have with me". Therefor that shows how a month only lasts 5 minutes in the potato field .
ReplyDeleteI agree with Morayma because every month lasts 5 minutes in the potato fields.
DeleteUsing the special bunny clock, one month in the potato fields lasts only five minutes.to support this in the number devil is said "Time runs faster here in the potato field. A month only lasts five minutes". He shows 1 rabbit then 2 rabbit then 3 rabbit and so on until you get to 21 rabbits. So that's how he showed the model.
ReplyDeleteThis comment has been removed by the author.
DeleteCan you explain what 1 rabbit, 2rabbit, 3 rabbits and so on until you get to 21 rabbits has to do with a month lasting 5 minutes in the potato felid
DeleteI agree with both of you but just like morayma said would you use specific evidence of what rabbits have to do next time.
DeleteA month in a potato field last five days. The special rabbit clock works like a ordinary clock but different. In the text it states "the hand shows months,not hours,"he said,"and a bell rings every time a month goes past." Also it states "when it reached one,the bell rang. A month had passed, the rabbits were much bigger and their fur had changed color-from white to brown."
ReplyDeleteBut I have a question:How do you know it's five?You didn't actually clarify why is five
DeleteThe book states " But ill have long since woken up before then. I have to go to school tomorrow morning...No problem,the number devil interrupted. Time runs faster here in the potato field. A month last only five minutes". Thank you Ibrahim for pointing that out
Delete1 begins the bonacci numbers because it starts the chain reactions and without one they are no bonacci numbers.In the beginning its 1=1 then it goes 1+1=2 and 2+3=5 and on. You see how one is in the beginning,but the mathematical term is Fibonacci numbers and the sequence I just did was called Fibonacci sequence.
ReplyDeletei agree with ibrahim i would also like to add on to make his answer stronger is a qoute from the book the number devil it states "A capital idea! And like most good ideas,it begins with-- what do you think? A one. Or rather 2 ones :1+1=2." This shows that the answer to this question is 2 ones .

DeleteI agree with ibrahima and I would like to add on that in the book the number devil it states "A capital idea! And like most good ideas,it begins with-- what do you think? A one. Or rather 2 ones :1+1=2." This shows that the answer to this question is 2 ones .
DeleteI agree with Ibrahim because the number 1 is the number that starts off the bonacci numbers.
DeleteI agree with Ibrahim and I would like to add on with the equation to get a Fibonacci number. Fn= Fn-1 + Fn-2. I think that n is equal to the number you want to get. I'm not exactly sure how to solve, because I could not find a lot of information.
DeleteI would like to answer question number 2 Which number begins the Bonacci numbers? Identify the mathematical term that refers to the Bonacci numbers. What number that begins the bonacci numbers is 1. In the story the number devil it states "A capital idea! And like most good ideas,it begins with-- what do you think? A one. Or rather 2 ones :1+1=2." This shows that the answer to this question is 2 ones .
ReplyDeleteQuestion 8: I say that the number devil used the special rabbit time watch and with this watch the time had only one hand and the numbers that it had were months. He said that every month a newborn rabbit would change its white fur from white to brown. He said that it would take another month for them to have baby rabbits. So the number devil pressed two months into the future and then the two adult rabbits had baby bunnies with white fur. Then he did the same and the kids now had kids with white fur and they had brown fur. He did that until the potato field was full of bunnies and Robert couldn't count the couples anymore. The number devil kept on doing this until robert couldn't take it anymore.
ReplyDelete
DeleteI agree with you
In book it has a special rabbit clock that each tick doesn't go by minutes it goes by month so each tick is 5 minute to a month .
ReplyDeleteI agree with Ibrahima
DeleteI agree with Ibrahima because in the book it states that a month lasts 5 minutes in the potato fields.
DeleteCan you identify a pattern? And it would be helpful if you put the question you were answering on top of your response
DeleteHow can you calculate the number of rabbits born without counting the rabbits?
ReplyDeleteYou can calculate the number of rabbits by multiplying 2 by the number of months that have passed since the mother rabbit gave birth. You're multiplying by two because rabbits only have 2 babies a month, according to one of the rabbits. For example, a scientist is studying a family of rabbits. He wants to know how many rabbits were born in the past 3 months. He can use the following equation to figure it out:
r=2m
(rabbits=2 times months)
This equation works for every situation that regards finding the number of rabbit babies born in past months.
Using the special rabbit clock, a month lasts 5 minutes in the potato field. The hand on the rabbit clock shows months, not hours and a bell rings every time a month goes past. So the bell rings every 5 minutes because that's how long a month lasts in the potato fields.
ReplyDeleteI agree with tama, and I will like to add on that in the book it states that a month lasts 5 minutes in the potato felid
Delete5) List 3 ways to generate other Bonacci numbers. Provide an example to justify your response.
ReplyDelete1. 1=1 1=2 you have to add the last two numbers add the together
2. 1+1=2 and jump one for 3 and jump another one to get 4
3. You can create a chart about the equation and the total of the bonacci number
6) Using the special rabbit clock, how long does a month last in the potato field?
ReplyDeleteAccording to page 113 of "The Number Devil" using the special rabbit clock, 1 month in the potato field lasts only a mere 5 minutes. "Time runs faster here in the potato field. A month only lasts five minutes. At least when you use the special rabbit clock I just happen to have with me."

9) Solve the tree problem on page 122.
Based on page 121 - 122 of "The Number Devil" by the time you reach the 9th line of the tree, there are 34 branches in all. The previous line, the 8th line had 21 branches. 34 is the 9th Fibonacci number and 21 is the 8th one. The tree goes on like that in both directions, for example the 6th line has the same amount of branches as the 6th Fibonacci number, 8.
I agree with you fataha
DeleteI agree with your answers Fataha. It is true that the month lasts 5 minutes using the rabbit clock. And when I counted the branches, I got the same amount that you did. Good job using text details so that it was easy to go back to prove your answer was correct.
Delete2) The numbers 1+1 begins the Bonacci numbers. When you have an equation like 1+1=2 then another, 1+2=3, you take the last two numbers and add them together and it keeps going down the line. Its like a pattern that doesn't stop.
ReplyDelete5) List 3 ways to generate other Bonacci numbers. You can use 1=1. Also, 1+1=2. And lastly, you can use a chart like its used on page 109 in The Number Devil to find the total of each equation.

ReplyDelete8) What type of data display is used to show the rabbit problem?
ReplyDeleteThe data display that is used to show the rabbit problem is a table. The table has six sections, and each section represents something different. I think this was an effective way of displaying data because the table did a good job of organizing the rabbit problem. In math class, I have used tables several times. I have used tables to organize a problem that has lots of different numbers. I have also used tables to help me solve complex problems. A table is a good math tool that helps lots of mathematicians solve challenging problems.
I agree with you Vianny. As clearly shown in the text, it is a table. I also agree when you said that tables can be used with large quantities of numbers. It is a good organization tool. I have noticed that when I don't use tables, it is harder for me to find work and I have a greater chance of getting the wrong answer. And when I use a table, I always know where my work is and I usually get an accurate answer. Also, I love your detailed answer
DeleteThe first number in Bonacci numbers is the number 1, as shown in the text. The mathematical term for a Bonacci number is a Fibonacci number. ach number equals the sum of the previous 2 numbers before it. And the sequence of the numbers is called Fibonacci sequence, according to Math is Fun.
ReplyDeleteI would like to talk about the origin of Fibonacci numbers. Math is Fun says that a man had a nickname, "Fibonacci." It means "Son of Bonacci." He invented the Fibonacci sequence and also let others know about the numbers we use today(1, 2, 3, 4...) which are called Hindu-Arabic numerals. This replaced the Roman numerals, which had no zero. So, this relates to Chapter 2 of the Number Devil, where we learned about Roman numerals.
DeleteThe terms in the Bocanni sequence are generated by adding the past 2 numbers before it. For example, the first 6 numbers in the Bocanni sequence are: 1,1,2,3,5, and 8. To get the number 8, you add 3 and 5, which are the 2 numbers that come before 8 in the sequence. A pattern I noticed is that every 3rd number is even, and the numbers in between the 6th, 9th, and 12th Bocanni numbers are odd. For example, the 3rd Bocanni number is 2, which is even. The 6th Bocanni number, 8, is also even. Finally, the 9th Bocanni number, 34, is even. The numbers in between, the 4th, 5th, 7th, and 8th Bocanni numbers are odd(3,5,13, 21). The Bocanni numbers that are a multiple of 3 in the sequence are even because the 2 numbers that come before it are odd. and an odd plus an odd equals an even. Take, the 6th Bocanni number, 8. The 2 numbers that come before it, 3 and 5, are both odd. Which is why the 6th Bocanni number becomes even. This number is true for the 12th, 15thg, 18th, and 21st Bocanni numbers, and so on for infinity.
ReplyDeleteSorry, Bonacci numbers
DeleteThe Bocannic sequence is adding the last two numbers ,& then you keep going down the line.The Bocannic sequence are (1,1,2,3,5,and 8.)
ReplyDeleteIn nature Bonacci numbers appear in the white calla lilly and trillium flowers.
ReplyDeleteOn the white calla lilly flowers there can be 2 petals and in the Bonacci sequence (1,1,2), so the calla lily's show the Bonacci sequence. Also the trillium flower can have at least 5 petals (1,1,2,3,5), so the trillium flowers show the Bonacci sequence.
ReplyDeleteUsing the rabbit clock a month only lasts 5 minutes and when the time is up one rabbit has 2 baby rabbits.You are able to count the number of rabbits there are without actually counting them by using the knowledge you already have which is every 5 minutes or a month on the rabbit clock they produce 2 babies so what you do is multiply the amount already there or born by 2 the one boy and girl.
ReplyDeleteThis comment has been removed by the author.
ReplyDeletequestion 7:In the potato fields you can calculate how many rabbits are there without having to count them by just every 5 minutes multiply that by two since the number devil said that two months last 5 minutes you multiply that by two and get the product. I also know this because in the book it stated that it took two months for a rabbit to have kids and change their fur color
ReplyDeletethe error on the singsong with the Bonacci numbers was that Robert said stop and that's why there was an error because numbers go on forever
ReplyDelete
