“I think they [the Standards] are going in the right direction but they are incredibly conservative, from my point of view. But again, I’d make reservation that if one has to work within the framework for schools as they are and curriculum as it is, maybe there isn’t very much room for making radical change. One of the ways in which the council is conservative is that it does not make full use of a computer -based construction of learning. I think the would have done much better if they had originally integrated Logo in their proposals. But there is no question that an imaginative Logo-using teacher wants to follow these Standards can do it better with Logo.” Seymour Papert

Rule 2: Extract the numbers from the problem in the order in which they appear. Be on the watch for numbers written in words Rule 3: If rule 2 yields three or more numbers, the best bet for getting the answer is adding them together. Rule 4: If there are only two numbers that are approximately the same size, then subtraction should give the best results.
Rule 5: If there are only two numbers in the problem and one is much smaller than the other, then divide the smaller in to the larger if it goes evenly. Otherwise multiply.
Rule 5: If there are only two numbers in the problem and one is much smaller than the other, then divide the smaller in to the larger if it goes evenly. Otherwise multiply. Rule 6: if the problem seems like it calls for a formula, pick a formula that has enough letter to use all the numbers given in the problem.

Rule 6: if the problem seems like it calls for a formula, pick a formula that has enough letter to use all the numbers given in the problem. Rule 7: Never, never spend too much time solving problems. Remember the best student in mathematics is the one who get to the bottom of the page first. This set of rules will get you through even the longest assignments in more than ten minutes with very little thinking.

One of the problems on the NAEP secondary mathematics exam, which was administered to a stratified sample of 45,000 students nationwide, was the following: An army bus holds 36 soldiers. If 1128 soldiers are being bused to their training site, how many buses are needed?

Story #3 Fraction Darts
Story #3 Fraction Darts The object of the Fraction Darts challenge is to quot;popquot; balloons located on a number line between 0 and 1. The darts are quot;thrownquot; by entering a number in fractional form.  Here is a glimpse of a game in progress. Two darts (7/8 and 3/4) have been thrown so far. Notice that 3/4 is too small and 7/8 is too big. What is your next throw?

“...Of course, many children memorize how to perform the mumbo-jumbo and manage to get an A but because they don’t understand what they are doing once the test is over they revert back to not knowing how to add fractions. If the meaning was there they would remember. Just how successful a person is in mastering school mathematics is largely a matter of how much meaning they can construct for the symbols manipulated and the operations performed on them. The problem many people have with school arithmetic is that they never get to the meaning stage; it remains forever an abstract game of formal symbols...” The Math Instinct – Why you are a Mathematical Genius by Keith Devlin – page. 248

It is a tremendous challenge to translate knowledge about teaching with technology from schools that are currently doing extraordinary things—both on their own and in the context of school improvement projects into knowledge that is broadly usable by the majority of schools.

  • 52. “I think they [the Standards] are going in the right direction but they are incredibly conservative, from my point of view. But again, I’d make reservation that if one has to work within the framework for schools as they are and curriculum as it is, maybe there isn’t very much room for making radical change. One of the ways in which the council is conservative is that it does not make full use of a computer -based construction of learning. I think the would have done much better if they had originally integrated Logo in their proposals. But there is no question that an imaginative Logo-using teacher wants to follow these Standards can do it better with Logo.” Seymour Papert

Remember the best student in mathematics is the one who get to the bottom of the page first. This set of rules will get you through even the longest assignments in more than ten minutes with very little thinking.

  • 190. “...Of course, many children memorize how to perform the mumbo-jumbo and manage to get an A but because they don’t understand what they are doing once the test is over they revert back to not knowing how to add fractions. If the meaning was there they would remember. Just how successful a person is in mastering school mathematics is largely a matter of how much meaning they can construct for the symbols manipulated and the operations performed on them. The problem many people have with school arithmetic is that they never get to the meaning stage; it remains forever an abstract game of formal symbols...” The Math Instinct – Why you are a Mathematical Genius by Keith Devlin – page. 248

So what’s so special about a turtle drawing pictures?Why did this MIT professor and a lot other people including Alan kay inventor the personal computer and negroponti who is sharing affordable laptops with 3rd world countries got so excited about it? I heard SP called the father of Logo speak at TC at the time his book mindstorms came out while I was doing my graduate work there. He talked about his passion for gears and how they impacted his attitude towards learning math and becoming a mathematician. He wanted to help others particularly children capture that feeling about ideas and learning. His curriculum were open-ended microworlds computer based learning learning environments In that process of engaging with these microworlds where powerful ideas are imbedded inside of neat phenomenon so that Learning formal ideas becomes more concrete. (For example in the Jinx we will see the power of variables)

They take on motion and shapes all directed by the student. Watch for Seymour’s wow response and the student says neat! --------- follow up with an example from Microworlds EX or scratch!!!!

In response to building criticism of the vagueness of their message they launched C & E standards for school mathematics in 1989 It included a reference to technology that was well buried in the document.

  156. In 1990 I became interested in power of story telling for the teaching of math. One of the first examples that got me excited was a movie that I saw back in 1970 called the Weird Number. It was about an event that happened in a very unusual town somewhere “on this side of the mountains”. The inhabitants were all rational numbers. One day there was a robbery at a bakery and someone stole a part of a loaf of bread. The thief was 2/3. However the sheriff was not able to capture the culprit because he wore a disguise. Can you spot him in the photo above? If you did you know more about how 2/3 disguises himself than any of the other numbers in the photo.
