My math lessons focus on student engagement and participation. I focus on developing conceptual understanding using manipulatives, specific language and activities. My lesson plans also include differientiated tasks that cater to the varying levels in the classroom.
1) To understand how and why the long division algorithm works
2) To use mathematically specific language to describe the steps in long division with meaning (rather than “divide, multiply, subtract, pull down)
Long division is one of the most difficult algorithms in arithmetic, and it is completely forgotten by many students. Using the blocks and proper mathematical language will help bring some meaning to this procedure. Alternately, the Partial Quotient (or Repeated Subtraction) method can be used for division. I recommend doing both with students so that they can choose the method that works best for them.
