Grade 9 Mathematics Outcomes
Add your name to the list below and pick a colour for yourself.
Add your name after an outcome of your choosing you’ll be preparing a lesson on.
Thanks to Carole Bilyk for the updated version here(as of Thursday June 18th).
Group Ideas Shared at Board Office (pre-requisite skills that mini-lessons could be prepared are mentioned as well as identifying PINCH POINTS for areas in which students need more direction on – feel free to add your ideas in your own colour of text in the strands below the appropriate outcome).
The document below was taken from:  Carole Bilyk at Manitoba Education and Training from an email attachment to S. Snyder (June, 2009)

Edutube…a new divisional project I’m a member of…

I can’t wait to record some 3 min. or less lessons on pinch points in the grade 9 curriculum document.

I will post a link to the GoogleDoc of our outcomes and highlights so far.

Go technology!
