    Some interesting activities to do with the Smart board in a mathematics classroom. I tried a couple of the activities and I did like that students were asked to estimate and predict. If teachers had clickers in their classrooms, this would be a great way of getting students to predict, record and then predict again and use the clickers for more than opening bell activities.

    Great new number sense math app. Cost $0.99 at this time but uses: the capabilities of the iPhone well (motion, graphics), multiple representations including linear and circle models, decimals, fractions, percents. Is fast moving and progresses beyond 0 to 1 to have students estimating values like 0.26 on a number line from 0 to 2.

math subtraction exploration

    Here is a phenomenal lesson, accessible to any child who knows how to subtract, and compelling to everyone, up to and including professional mathematicians. Get a kid engaged in it, and they'll do hundreds of subtraction problems without complaint, because it's helping them solve an honest mathematical mystery. I've seen this idea discussed in math education circles, but I haven't found any references to it online, so I want to share it here.

      I a little scared about this so far...:( I tried something like this once with not so great results...but let's keep reading.

      I felt the same way b4 starting Lit Circles
  • the expert for each chapter recounted the key elements of the chapter to the rest of the kids, who hadn’t read it After this round of highlights from each chapter, the groups transitioned into general discussion about the five-chapter segment of the novel.

      ok confirms what I thought
  • Chapter 8 in MacDougal-Little’s The Americans covers the reform movements between1820-1850. There are four distinct strands which emerged during this period- religious renewal, abolitionism, the early women’s rights efforts, and workplace reform
  • she did want them to sample Dickens’ voice and pick up some cultural background from the era.

  • having every student read every page in the textbook may not be the only alternative

      OK: i agree...reading is not always comprehension
  • Are kids actually working, thinking, and engaged with the text we assign- or are they just imitating a sentient life form while remaining functionally unconscious?
  • But textbooks frequently can be easily subdivided

      OK - allows students to become teachers to other students, a role at which a lot of them excel.

      X I'm not sure I agree. Often with jigsaw when the "experts" get together students are more interested in "getting the answers" than truly engaging with that text (ie. asking questions, making inferences, etc) I suppose it depends on the follow-up activity and HOW they go about sharing their info.

      :) good point
  • when you have to read, write, talk, and listen, it is much harder to “fake it” than it is to slide through a textbook assignment without understanding.
