Reflection: Conferences Hit the Target with Subtraction Number Sentences - Section 3: Independent Practice

 

For the majority of my students they found success with this practice and were able to show me six perfect number sentences.  I had a couple of students who did not attend to details and the numbers they wrote in the story problem did not match the number sentence they created, so I visited with them.  The video in the resource section is of one student who needed scaffolding to find 10-0=10. One problem I am starting to see a pattern of throughout the subtraction lessons is if the problem says 7-2=, the student may show me 7 and when I say take away 2, they put the seven down and show me 2.  They are having a difficult time thinking of larger numbers as being composites of smaller numbers, so I see that decomposing numbers is still a leap for some of my students. I plan to continue to practice this process with these students and will be providing a math center for more time on this task.

Big Idea: Blending is not just for ELA teachers! Today students will learn to "blend" (combine) two sets of dots and then compare the number to another using greater than by playing versions of previous learned activities.
