Place Value Marshmallow Math

I downloaded this wonderful idea from Babbling Abby (she is Ah-Mazing).  After a quick review of ones and tens, I introduced hundreds by showing my students how to do this Marshmallow Math.  Be sure to explicitly show them how to set up the marshmallows and use the tooth picks appropriately beforehand.  In addition to practicing place value this lesson also provided a yummy snack in the end!
