> A small group of us are working on an OER for OLPC
> and have chosen the topic; Fractions
> Here is where we need your help:
> *
> * Identify Models of Fractions and how we can
> present these different models in concrete forms
> as a kind of Fraction Exploratorium
> * Identify common mis-conceptions learners have
> about fractions and using them and identify ways
> of addressing these mis-conceptions.
> * Identify Activities we can use to teach
> fractions (I spend most of my time in Etoys, but
> we should use Turtle Art, Scratch and others)
> * Identify existing lessons we can refer to or
> re-render
> (ex: http://illuminations.nctm.org/LessonDetail.aspx?ID=U152)
> * Identify virtual manipulatives needed (I have
> cuisenaire rods and pattern blocks in Etoys,
> here is a nice one at Illuminations)
> * Identify physical manipulatives that can be used
> (and id how can be easily and cheaply created by
> kids/teachers)
> * Identify no computer, concrete activities kids
> can do (ex: 1) Fold a paper in half and cut, 2)
> Label as 1 piece of X needed to make a whole
> sheet; repeat)
> * Create/Identify a lesson, manipulative, blog
> post or video each day. Okay ambitious, but
> do-able (for short sprints). It helps me keep
> the perfect from being the enemy of the good and
> gets me focused and moving. I look at it as
> the equivalent of some writers practice of
> writing something every day.
> Also am working on creating "A Fraction A Day" well
> almost everyday, and guest posts/ideas/suggestions
> for improvement etc are welcome.
> Thanks,
> Stephen
