Reflection: Intervention and Extension Adding Four Three-Digit Numbers - Section 4: Independent Practice


During the independent practice section of this lesson, I support students in the A group on adding four three-digit numbers.  Many of my students in this group struggle with  number sense and need extra help to internalize strategies and explain their thinking.  When I work with my intervention group, I start by going over each of the strategies. I then have students work in partners to start the first problem.  Allowing students to work in partners helps them to "think aloud" and explain their thinking to another person.  As students work, I help individual pairs, stopping to ask them to explain their thinking or if they are struggling, reminding them of how the strategy works.  Once all of the pairs have finished, I have at least on pair share out.   This process of sharing out allows students to build confidence and helps students to internalize their strategies.  

During the second independent practice problem, my intervention group students work independently and I work one-on-one with any student who had serious problems during the first independent practice problem.  During this time, I might model the problem or have the student talk me through what they understand of the problem. 

This extra practice and support allows many of my struggling students to persevere through on-level tasks and helps me to develop their number sense in authentic ways.
