Everybody Add and Subtract Now!

The afternoon Grade 2 PLC asked to look at different strategies they could use to teach addition and subtraction to their class.  The group had some great discussions about the pros and cons for teaching the different strategies and also for ways to try the strategies out in the classroom.  One discussion was about how great it would be to divide up some of the strategies to make them be "must covers" for different grades.  This way, as the students progress through the grades and into higher numbers in addition and subtraction they would already have some strategies in place, and be able to add strategies to their tool kit.  See which of the strategies you are familiar with, and see which ones will be added to your tool kit.  If you want to learn more about addition and subtraction strategies I highly recommend reading "Young Mathematicians at Work:  Constructing Number Sense, Addition, and Subtraction" by Cathy Fosnot.  You can get the book from Pearson.  The ISBN is: 0-325-00353-X
