Reflection: Adjustments to Practice Tic Tac Toe - Subtracting Mixed Numbers - Section 2: Concept development


As you can see in my video reflection, the tic toe game was a great way for my students to practice the skill of subtracting mixed numbers.  I still have a few students that struggle with a number method and also don't want to model the problem, so I need to make sure I work with these students to ensure they have a strategy they can use to subtract mixed numbers.  This lesson was an adjustment to practice and something I came up with just hours before the lesson. I didn't want to stand at the board and deliver a bunch of strategies for how to subtract mixed numbers, I really wanted the strategies to come from the students.  This game definitely allowed the strategies to come from the student and then my job was simply to elicit the strategies and guide student thinking.
