## Reflection: Solving Subtraction Number Stories- In Space - Section 2: Presentation of Lesson

I start this lesson out very basic similar to how we started with addition.  I want the students to develop a conceptual understanding of subtraction and not get confused by the similarities and differences in the symbols used in addition and subtraction equations.  I found that after the first few problems most students felt very successful after today's lesson.  My observations showed that almost every student was able to solve the problems easily.  Going into the next few lessons with this feeling of confidence and ability to succeed will make learning subtraction easier and more enjoyable for the students.
