IIS: Section II: How the IMP Curriculum Is Different - 0 views

  •  
    It is problem-centered. It is integrated. It expands the content scope of high school mathematics. It focuses on developing understanding. It includes long-term, open-ended investigations. It can serve students of varied mathematical backgrounds in heterogeneous classrooms. The IMP curriculum is problem-centered. Units of the IMP curriculum generally begin with a central problem or theme. Students explore and solve that problem over the course of the unit. How long does it take for a 30-foot pendulum to complete twelve periods? How can you predict the length of a shadow? What is the best design for a honeycomb? What is the probability that the baseball team currently in the lead will win the championship, given the current record of its closest rival? What's the best way to resolve the conflicts of a particular land-use situation within the constraints of competing political and social forces? When should a diver be released from a rotating Ferris wheel in order to land safely in a moving tub of water?

A Set of Excellent iPhone Math Apps for the Older Child | GeekDad | Wired.com - 0 views

  • These are the addition problems and method we all learned in school.
  • This app has you adding from left to right instead of starting in the ones place, which goes against everything I learned.

      "against everything I learne"...that's cuz we teach it wrong!!
  • This one is unusual, dividing up some of the numbers into their parts (whole ones, whole tens, etc.), and subtracting the parts.
  • ...2 more annotations...
  • it teaches you to subtract the tens place first, and then subtract the ones place. But in the ones place you end up with a negative number.

      Hmm, subtracting left to right ? Like we read? What a novel idea!!
  • It makes multiplying large numbers easier, and allows you to see it all visually.

      Do either of you know about lattice multiplication??
