Reflection: The Block Battle-Comparing 11-20 with More - Section 4: Independent Practice and Informal Assessment

 

If you watch the video clip included with this lesson, you will hear a student ask, "What if they are equal?"  After the students responded to the problem I had posed for them, I responded to her question and told her that we would circle both.

I was so excited to observe her applying knowledge from our previous lessons on comparing quantities and numbers to this lesson.  What I think is important to note is that she did not ask what we do if the numbers are the "same", but instead she demonstrated her knowledge of mathematical academic vocabulary.

It is so important that students are exposed to academic vocabulary regularly.  It is important to scaffold the language.  When I introduce a new vocabulary word, I make sure to couple it with a word the students understand at first (for example, saying, "They are the same or equal.") Eventually, when I feel the students understand the term, I will stick with just the academic vocabulary.  This is so important, especially for English Language Learners or students with limited language exposure.  Probably one of my greatest frustrations of standardized testing is that it does not test the "skill" as much as it does the understanding of vocabulary.  I know that my students need to get exposed to a wide array academic terms to score well on these tests.  More importantly, they need the knowledge of these terms to be successful in learning mathematics in the future.
