## Reflection: Problem-based Approaches Story Problems Subtraction - Section 2: Direct Instruction

Kinders have a very difficult time grasping subtraction. The best way to approach the concept is to start with story problems. If the kids can visualize the story being told, they can easily learn to represent it with dots or pictures. Once they have practiced that long enough, introduce the numbers that represent the objects and record only the numbers. Once they are able to clearly connect the objects in the story to the recorded numbers, add the signs. While you are teaching this concept, emphasize the concept that in order to subtract, the story must start with the larger number. This helps to continue to develop number sense as they learn.
