## Division Strategies and Algorithms: Great Guided Math Lessons

Can you show your thinking about 250/50 in more than one way? What about your students? Can they discuss this problem with numbers, words and pictures?

Division with Virtual Manipulatives

More Division with Virtual Manipulatives (I would use real base ten blocks and then show the process with virtual manipulatives).

Short Division (Notice the use of her language? How could you help describe this process by using language that is descriptive of the actual place of the numbers?)

Be sure to look at all the Schultz videos on different strategies and algorithms for division (scroll all the way down). Also take a look at the other posts on strategies and algorithms in this series on operations. I always encourage teachers to do this type of work in small guided math groups so that students can get a chance to explain their thinking and listen to the ideas of others. Also remember that the new math common core is encouraging us to build a repertoire of strategies and algorithms for the basic operations. Of course, teach the traditional algorithm as well, but teach it with conceptual understanding as well as procedural fluency!

Happy Mathing,
