I wanted to challenge my first grade smarties to really understanding the various types of word problems we've been practicing in class. I felt that if they could name the type of problem they were working with the writing the number sentence would come a little more easily. I created this Prezi to present the info, and then we worked all week on identifying and solving the various problems: start unknown, sum unknown, difference unknown, and change unknown.
