Pretending to guess…Great! I guessed a pair of socks! Am I right again! Throw in a mathmatical equation that always has the same 9 sets of answers, make all 9 sets the same gift, Add a mass of other gifts with letters and graphics that all seem to blend together. Forget how the equation to arrive at multiples of 9 works. All you need to know is, ather the basic sum is performed only one of thes numbers will be returned.
Try it. All you need to know is, after the basic sum is performed only one of thes numbers will be returned. As many of the comments show, we are a nation of math illiterates. And these people presumably vote. For those still confused do this simple test: 1 Click into the gift screen do not pick a number first. It WILL be the gift in box 90 everytime. Hey kids suprise suprise. Automatically you bring the mouse pointer to that number, the program reads this and voila! Let me explain. And nothing could be further from the truth.
You will notice that each of those nine numbers is exactly 9 more than the previous number. Now, the same holds true for each of the ten point ranges in the range of That is, if you pick something the result is 18, if you pick something the result is 27, and so on. But, as I hope I have demonstrated, no mystery here.
Therefore, the first 9 boxes of the 99 boxes are irrelevant, but they tend to add to the mystery. Numbers is numbers and people can do all kinds of tricky things with them like, er, the government. Example: 9,18,27,36,45,54,63,72,81… are all Oven Mitt or Ref. Magnet or whatever. None of the other numbers matter at all. Those will always be the same. Any two digit number, say 41, minus the digits that make the number, , will always equal a multiple of 9.
Now since Robin knows you have to calculate a multiple of 9, all the gifts that are in the numbers 9,18,27,36,45,54,63……… Are all the same gift. They just change the multiple of 9 gifts each time you play, but they are all the same gift for that play.
Try the game again and watch the gifts under these numbers. There are lots of odd number patterns , check this out!!! Tell someone that you can square any 2 digit number ending in 5 in your head faster then they can on a calculator!! Howz it work ya say?? It works from 15 to 95 quick and easy.
It actually works on all digits that end in 5 but of course becomes more complicated beyond 2 digits. The principle does still work however. Once you get the concept you can literally do the equation in your head faster then someone can with a calculator!!
Each box that is a multiple of 9 is the same gift. Robin will guess incorrectly. The math thing is a clever trick. It switches it around. Haha, untill you actually look at it, it happens seemingly fluidlike. I cannot believe the number of people that could not understand how this is done. I mean sure, many people have a hard time with algebra, but the frigging 9 times tables???
How can anyone get the answer to how it is done, then try it again and still not understand how easy it is. I think our future is not so bright after all. And somebody said something about why they need a calculator? Bobby, algebra and trigonometry, and calculus, and linear algebra, and differential equations put a lot of money into my hands, and allowed me to do some amazing things like take a dive to m in the Alvin research sub and drive around in the mud at the bottom of the ocean, for example.
We need science and math people in a big way. Secret: every 9th box is the same. Your choice will be a multiple of 9. I enjoyed the game and it was fun doing it over and over to see if the game would be wrong. It was like it was really reading your mind! The scientific explanation took the fun away.
This chart shows all possible responses for any 2 digit number. Note that each answer is a multiple of 9. You are correct on the digits 1 thru 8. Also, they included 82 thru 99 just to confuse us.
Yes, I think they did include the digits to confuse us. And your right about anything higher than 81 being impossible. Since 99 is obviously the highest two digit number, it would give you the highest possible outcome….
I believe you love math like I do. We also want to encourage collaboration in the classroom and this allows children to learn from each other and also gives them a chance to explain their reasoning and listen to others explain theirs. This dynamic helps not only with the particular problem at hand but at problem-solving and reasoning in general.
I think this is very hard to replicate in an online classroom where the discussions are disjoint and spread out over time. In the actual 4 th grade classroom, students might work on this problem individually, then work in small groups and try to clarify and connect their approaches, and then finally share their results with the class.
As this happens, the teacher would sever as the GUIDE on THE SIDE rather than the SAGE on the STAGE and help children better represent or explain their methods, use mathematical language and precision, connect various ideas and methods, and make sure all students learned the big ideas like multiples of 9 procedural , place value conceptual and explaining your reasoning problem-solving. It is difficult to connect the sharing and provide a meaningful summary in the online discussions so make sure you try to do that as we move forward with other problems and discussions.
I think that it is always a multiple of 9 because of the base 10 system. Whenever you subtract the digits in the number from that number you are going to get a multiple of 9 because 9 is the highest one digit number. Where you knew the answer but were unsure how to explain it. Working together as a group not only provides answers and methods but also many ways to explain and to enhance explanations.
Procedural fluency in mathematics. Many of the key ideas to this problem solving task and teaching with problem-solving can be seen in the implementation of the MPS—which I copied from one of your classmates:. I definitely had to persevere when solving this problem, and I had to make sense of how the base ten concepts apply to this problem and ultimately make it work. Reason abstractly and quantitatively- In this problem, I really had to attend to the meaning of the quantities of the number not just the computations.
Construct viable arguments and critique the reasoning of others- It took me a while to try and type up my solution for our first assignment with Regifting Robin as well as answer the first question of this discussion. I really had to try to be as articulate as possible when stating my opinion on why the mathematics behind this game makes it work.
Model with mathematics- In order to solve this problem, I represented the numbers with visual models, represented the number using an algebraic equation as suggested, and did simple subtraction problems. I applied what I knew using different strategies to try to solve the problem. Use appropriate tools strategically- I knew the tools that would be most useful for me when solving this problem were simply pencil and paper.
I needed to write down my thinking, draw pictures, create equations, etc. Maybe I shouldn't give away their little trick. Well, in this case it was way too easy. Maybe this will encourage them to come up with more elaborate tricks. The basic idea is: pick a 2 digit number, like 37 subtract both the number in the tens place and the number in the ones place from the original number find the number you have left on a grid of "gifts" and robin will guess what your gift was You may have seen stuff like this before and figured it out.
I know you may be saying "duh", but a lot of people gloss over this little detail. In the gift squares, there are options. Like with all Remington bolt actions, expect a lifetime of rock-solid reliability. Your artwork may even end up featured on the Toontown website. Hong Kong city breaks have to involve a trip to Victoria Harbour, where a ride on the Star Ferry will provide you with a great view of the city's sights. Partzilla also work with motorcycles, snowmobiles, speed boats and other how does regifting robin game work powerful machines that need due care and attention to keep them in working order.
