>   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
