## Reflection: Adjustments to Practice Subtraction Fluency and Vocabulary Assessment - Section 3: Independent Practice

Please look at the student test samples; Student AStudent BStudent C and you can see some of the great responses I received from my students on the vocabulary section. Yet, not every student had such great success.  Out of my 22 students who tested, I had 5 who could not supply me anything that made sense for any of the vocabulary words.  When I break it down further, of my 17 students who found success, I had 6 who only found success with 75% of the words.  There was no one word that was the most difficult for them to use, so no clear pattern of a more difficult vocabulary word over another.

What it actually came down to was my students found it difficult to "write math." I learned they could easily use these words verbally and explain math processes to me.  They found it difficult to do the same thing in writing.  For example, they could verbally say and write 7-2=5, but did not understand the same thing could be written in words; seven minus two equals five.  It really surprised me that even after reviewing and writing sentences together that they could still not make the connection.  I stopped the test for a moment and pointed out to them the same things they are saying when they state a problem to me is the same as writing the words on paper. This seemed to help and thank goodness I still had the majority of my test find some success. However, this assessment taught me that I am not having my students write enough in math.  I plan to incorporate some journal writing in future math lessons to encourage them to connect writing to math.

Adjustments to Practice: Writing is important in math

# Subtraction Fluency and Vocabulary Assessment

Unit 11: Subtraction Strategies
Lesson 7 of 7

## Big Idea: First graders need to be able to solve subtraction facts with fluency and use math vocabulary to communicate processes and explain their ideas. This assessment will allow me to see who needs further instruction or is ready for advanced material.
