I am holding a release party today, Sunday September 11, 2011 to launch my newest collection of Mental Math Strategy Units. Today from 8:00 am until 10:00 pm CST you can download the 87-page "Doubles" strategy unit for FREE!
Additionally, the other three units in the collection are marked at 20% off for today only! This includes the strategy units of "Counting On," "Doubles Plus One" and "Making Ten."
In the next couple of months I will be adding to this collection with units on adjusting to make multiples of ten and subtraction strategies.
