Reflection: Quizzes RTI Decomposing: Dice, Drawing and Explicit Instruction - Section 4: Quick RTI Quiz

 

With the exception of two students, the students who were practicing their dice games and the students at my back table grew and are better at mastering subtraction using decomposition skills. Of the 17, 15 passed with flying colors solving each one correctly. The two who did not master the quiz can decompose the improper fractions, but cannot compose improper fractions from mixed numbers. They do not notice the smaller fraction's placement. I need to teach them to use "math mountain" as a strategy to help them organize their thought. Math mountain is a triangular drawing with the total on the top and the addends placed at the bottom. That way, the numerator should stand out better.
