Reflection: Intervention and Extension Two Digit Subtraction With Rounding - Section 2: Active Engagement


Game play is one of my favorite times to assess student thinking and application. While they are busy "playing" I can ask questions about strategy, points, problems, and also extend to modify when needed.  

In the videos above, you heard students discuss several their strategies, and I am sure you were able to define several mini-lesson teaching points. 

All too often, when students are playing math games, teachers check papers or work with small groups.  While this is necessary work, games are active teaching time and often represent some of the best opportunities to help students make meaning of their thinking. I do believe a great many lessons can be taught in a short time during the games.
